Cisco Training In Your Own Home Considered

If Cisco training is your aspiration, and you’ve not yet worked with routers or network switches, you should first attempt CCNA certification. This will provide you with knowledge and skills to work with routers. The internet is made up of hundreds of thousands of routers, and large commercial ventures with many locations also need routers to allow their networks to keep in touch.

It’s very probable you’ll get a job with an internet service provider or a big organisation which is located on multiple sites but still wants secure internal data communication. These jobs are well paid and in demand.

Getting your Cisco CCNA is perfectly sufficient to start with; don’t be cajoled into attempting your CCNP. Once you’ve got a few years experience behind you, you will have a feel for whether you need to train up to this level. If so, your experience will serve as the background you require to take on your CCNP – which is quite a hard qualification to acquire – and mustn’t be entered into casually.

One thing you must always insist on is 24×7 round-the-clock support with trained professional instructors and mentors. Too many companies only seem to want to help while they’re in the office (9am till 6pm, Monday till Friday usually) and nothing at the weekends.

Never buy certification programs which can only support trainees through a message system after 6-9pm in the evening and during weekends. Trainers will give you every excuse in the book why you don’t need this. The bottom line is – support is required when it’s required – not when it’s convenient for them.

We recommend that you search for training programs that have multiple support offices across multiple time-zones. Each one should be integrated to give a single entry point together with access round-the-clock, when you want it, with no fuss.

Never make do with a lower level of service. Direct-access 24×7 support is the only way to go when it comes to IT study. Maybe late-evening study is not your thing; often though, we’re working when traditional support if offered.

Beginning with the idea that it makes sense to home-in on the employment that excites us first, before we can even mull over which development program fulfils our needs, how can we choose the right direction?

Because without any solid background in computing, how should we possibly understand what someone in a particular job does?

Arriving at a well-informed resolution really only appears from a methodical analysis of several shifting key points:

* Personalities play an important part – what things get your juices flowing, and what are the areas that put a frown on your face.

* What time-frame are you looking at for your training?

* How highly do you rate salary – is it the most important thing, or is job satisfaction higher up on your priority-list?

* Understanding what the main IT roles and markets are – and what makes them different.

* Taking a cold, hard look at the level of commitment, time and effort you can give.

To be honest, it’s obvious that the only real way to investigate these matters tends to be through a good talk with an advisor or professional who has years of experience in IT (as well as it’s commercial requirements.)

Commercial certification is now, undoubtedly, beginning to replace the traditional academic paths into IT – but why is this?

As we require increasingly more effective technological know-how, the IT sector has moved to the specialised core-skills learning only available through the vendors themselves – in other words companies such as Microsoft, CISCO, Adobe and CompTIA. This frequently provides reductions in both cost and time.

Many degrees, for example, become confusing because of a lot of background study – with much too broad a syllabus. Students are then prevented from getting enough core and in-depth understanding on a specific area.

What if you were an employer – and you required somebody who had very specific skills. What is easier: Trawl through loads of academic qualifications from several applicants, trying to establish what they know and which vocational skills they’ve acquired, or choose particular accreditations that specifically match what you’re looking for, and make your short-list from that. Your interviews are then about personal suitability – rather than on the depth of their technical knowledge.

A study programme must provide a nationally accepted exam as an end-result – and not some unimportant ‘in-house’ diploma – fit only for filing away and forgetting.

All the major commercial players like Microsoft, Cisco, Adobe or CompTIA all have nationally recognised proficiency programmes. Huge conglomerates such as these will make your CV stand-out.

QUESTION 1:

You work as the network administrator at Certkingdom.com The Certkingdom.com
network consists of a single Active Directory domain named Certkingdom.com All
servers on the Certkingdom.com network run Windows Server 2003 and all client
computers run Windows XP Professional. The Certkingdom.com network contains a
print server named Certkingdom -PR01 that has a built-in network interface.
A Certkingdom.com user named Andy Reid is a member of the Research and
Development department. Andy Reid complains that he cannot print to a print
device attached to Certkingdom -PR01.
You have received instruction to ensure that Andy Reid can print to the print
device. First you verify that the IP address for Certkingdom -PR01 is correct and that
the latest drivers for the print device are installed. You now want to verify that the
print jobs are being sent to the correct MAC address for Certkingdom -PR01.
What should do?

A. On Certkingdom -PR01, run the net session command.
B. On Certkingdom -PR01, run the netstat command.
C. On Certkingdom -PR01, run the netsh command.
D. On Certkingdom -PR01, run the netcap command.

Answer: D

Explaination: Netstcap.exe is a command line tool that could be used to capture the
network traffic. A filter can be created to be used during the capture to determine the
MAC address the print jobs are being sent to. The Network Monitor Capture Utility (
Netcap.exe) can be used to capture network traffic in Network Monitor. Netcap provides
capture abilities only from a command prompt; to open the resulting capture (.cap) files,
you must use the full Network Monitor interface. Netcap is installed when you install the
Support tools that are on the Windows XP CD-ROM. Netcap provides capture abilities
that are similar to the version of Network Monitor that is included with the Windows
Server products; however, you must use Netcap at a command prompt. Netcap installs
the Network Monitor driver and binds it to all adapters when you first run the Netcap command.
Incorrect Options:
A: The net session command can be used to view the computer names and user names of
users on a server, to see if users have files open, and to see how long each user’s session
has been idle. Net session manages server computer connections – used without
parameters, net session displays information about all sessions with the local computer.
B: The netstat command is not a utility to use when troubleshooting NetBIOS names, but
is used to display TCP/IP and port information.
C: The Network Shell utility (Netsh.exe) can perform a wide range of system
configuration tasks. You can use commands in the Netsh Interface IP context to
configure the TCP/IP protocol (including addresses, default gateways, DNS servers, and
WINS servers) and to display configuration and statistical information.

QUESTION 2:

You work as the network administrator at Certkingdom.com The Certkingdom.com
network consists of two subnets. All servers on the Certkingdom.com network run
Windows Server 2003 and all client computers run Windows XP Professional. All
servers are located in a central data center that uses a single IP subnet and all client
computers are located in one subnet.
The data center contains two routers named Certkingdom -SR01 and
Certkingdom -SR02, two domain controllers named Certkingdom -DC01 and
Certkingdom -DC02, and two file servers named Certkingdom -SR03 and
Certkingdom -SR04. The IP addresses of these servers are indicated in the table
below.

Host name IP address
Certkingdom-DC01 10.10.10.1
Certkingdom -DC02 10.10.10.2
Certkingdom -SR01 10.10.1.1
Certkingdom -SR02 10.10.1.2
Certkingdom -SR03 10.10.11.1
Certkingdom -SR04 10.10.11.2

You have received instruction from the CIO to install a new database server in the
data center. You install Windows Server 2003 on a new server computer named
Certkingdom -DB01 and hand it over to a database administrator named Dean
Austin. Dean Austin installs Microsoft SQL Server 2005 and makes some changes to
the TCP/IP settings on Certkingdom -DB01 as shown in the following table.

Parameter Value
IP address 10.10.1.3
Subnet mask 255.255.255.0
Default gateway 10.10.1.2

Later, Dean Austin complains that Certkingdom -DB01 cannot communicate with the
other servers in the data center. All other servers in the data center can
communicate with the other servers as well as the client computers. You log on to
Certkingdom -DB01 and attempt to ping Certkingdom -DC01 but you receive the
following error message: “Destination host unreachable”.
What should you do to ensure that Certkingdom -DB01 can communicate with the
other computers in the Certkingdom.com network?

A. Configure Certkingdom -DB01 with a default gateway of 10.10.1.1.
B. Configure Certkingdom -DB01 with a subnet mask of 255.255.0.0.
C. Configure Certkingdom -DB01 with an IP address of 10.10.10.3.
D. Configure Certkingdom -DB01 with an IP address of 10.10.11.3.

Answer: B

Explaination: Large networks are subdivided to create smaller subnetworks to reduce
overall network traffic by keeping local traffic on the local subnet and sending all
nonlocal traffic to the router. In order to create a subnetwork, we need to have a system
for addressing that allows us to use the network ID and host ID within the class-based
system. This is accomplished through the use of a subnet mask. To determine the
appropriate custom subnet mask (typically referred to simply as subnet mask) for a
network, you must first:
1. Determine the number of host bits to be used for subnetting.
2. Determine the new subnetted network IDs.
3. Determine the IP addresses for each new subnet.
4. Determine the appropriate subnet mask.
Incorrect Answers:
A: You need to assign the correct subnet mask to ensure connectivity.
C, D: The problem in this scenario is not a faulty IP address. It is the appropriate subnet
mask that has to be determined to enable connectivity.

QUESTION 3:

You work as the network administrator at Certkingdom.com The Certkingdom.com
network consists of two subnets named Subnet A and Subnet B. Subnet A and
Subnet B are connected by a router. All computers on the Certkingdom.com network
are configured with static IP addresses. All network servers run Windows Server
2003 and all client computers run Windows XP Professional.
Certkingdom.com hires a new Sales manager named Amy Wilson. You install a new
client computer named Certkingdom -WS291 for Amy Wilson. You then add
Certkingdom -WS291 to Subnet A. The relevant portion of the network is configured
as shown in the exhibit.

However, Amy Wilson complains that Certkingdom -WS291 cannot communicate
with other hosts on the network.
What should you do to ensure that Certkingdom -WS291 can communicate with all
local and remote computers on the Certkingdom.com network?

A. Configure Certkingdom -WS291 with a default gateway of 192.168.28.84.
B. Configure Certkingdom -WS291 with a default gateway of 192.168.2.1.
C. Configure Certkingdom -WS291 with a subnet mask of 255.255.255.128.
D. Configure Certkingdom -WS291 with a subnet mask of 255.255.255.192.

Answer: C

Explaination: It is evident from the exhibit that the file server and
Certkingdom -WS291 have a different subnet mask. This is the reason why they
cannot communicate with each other. You must therefore change the subnet mask
of Certkingdom -WS291 to 255.255.255.128.
Incorrect Answers:
A, B: The problem is not the gateway IP address that is faulty, but rather the subnet
mask.
D: This option suggests the correct object that has to be changed, but it gives the wrong
subnet mask.

QUESTION 4:

You work as the network administrator at Certkingdom.com The Certkingdom.com
network consists of a single Active Directory domain named Certkingdom.com
Certkingdom.com has its headquarters in Chicago and branch offices in Dallas and
Miami. All servers on the Certkingdom.com network run Windows Server 2003 and all
client computers run Windows XP Professional. You work in the Miami branch
office.
The network at the Miami branch office consists of 25 different subnets, each with a
maximum of six computers. The network administrator at headquarters has
allocated the 192.168.3.0/24 network address to the Miami branch office.
You install a new server named Certkingdom -SR21 in the Miami branch office. You
need to configure the Internet Protocol (TCP/IP) properties for Certkingdom -SR21.
You configure Certkingdom -SR21 with an IP address of 192.168.3.44. What subnet
mask should you use?

A. A subnet mask of 255.255.255.0.
B. A subnet mask of 255.255.255.128.
C. A subnet mask of 255.255.255.192.
D. A subnet mask of 255.255.255.240.
E. A subnet mask of 255.255.255.248.

Answer: E

Explaination: The network address is: 192.168.2.0/24, which means
11111111.11111111.11111111.0 in binary.
Therefore, you can use the last octet to configure the 30 subnets and 6 hosts in each
subnet
You need only six host PCs. When you convert to binary, it is: 00000111. As a result,
you use 3 bits.
This leaves 5 bits for the subnets 11111000 converted to decimal:
128+64+32+16+8=248, therefore the subnet mask will be: 255.255.255.248.

QUESTION 5:

You work as the network administrator at Certkingdom.com The Certkingdom.com
network consists of a single Active Directory domain named Certkingdom.com
Certkingdom.com has its headquarters in Chicago and a branch office in Dallas. All
servers on the Certkingdom.com network run Windows Server 2003 and all client
computers run Windows XP Professional. You work in the Dallas branch office.
The network at the Dallas branch office consists of a single subnet that contains 150
client computers and 12 servers. The network administrator at headquarters has
allocated the 10.10.0.0/16 network address to the Dallas branch office.
You have received instruction from your manager to place all servers at the Dallas
branch office into a separate subnet that uses the 192.168.10 public addressing
scheme. Your manager asks you to make allowance for a maximum of 30 servers in
the new subnet.
Which subnet mask should you use for the new subnet?

A. 255.255.255.224
B. 255.255.255.240
C. 255.255.255.248
D. 255.255.255.252
E. 255.255.255.254

Answer: A

Explaination: A 255.255.255.224 subnet mask gives five host address bits, so the
maximum number of host addresses is 2 ^ 5 – 2 = 30 host addresses. Thus
255.255.255.224 is the only subnet mask that will allow for sufficient IP addresses in
case of further growth, whilst still conserving as many current addresses as possible.

QUESTION 6:

DRAG DROP
You work as the network administrator at Certkingdom.com The Certkingdom.com
network consists of a single Active Directory domain named Certkingdom.com All
servers on the Certkingdom.com network run Windows Server 2003 and all client
computers run Windows XP Professional.
You have installed a new server named Certkingdom -SR06 on the network. The
relevant portion of the network is shown on the exhibit.

You want to configure Certkingdom -SR06 with a valid static IP configuration.
Certkingdom -SR06 must be able to communicate with all hosts on the network and
on the internet. You also need to configure Certkingdom -SR06 to use the DNS server
on the local subnet for name resolution. In addition, you must configure redundancy
for name resolution.
How should you configure Certkingdom -SR06?
To answer drag the appropriate IP addresses and Subnet masks to the appropriate
places.

Answer:

Explaination:
The Class C address 192.168.0.100 has to be the IP address to enable
Certkingdom -SR06 to communicate with all hosts on the network and on the internet
as 192.168.0.1, 192.168.0.2 and 192.168.0.110 are already in use. 192.168.5.2 and
192.168.5.100 are on the wrong subnet, and besides, 192.168.5.12 is already in use.
The subnet mask for this Class C address is 255.255.255.0. The default gateway
should be 192.168.0.1. To configure redundancy for name resolution, configure the
preferred DNS server/primary address as 192.168.0.2, and the alternate DNS
server/secondary address as 192.168.5.2.

QUESTION 7:

You work as the network administrator at Certkingdom.com The Certkingdom.com
network consists of a single Active Directory domain named Certkingdom.com All
servers on the Certkingdom.com network run Windows Server 2003 and all client
computers run Windows XP Professional. Certkingdom.com has its headquarters in
Chicago and branch offices in Dallas and Miami. You work in the Miami branch
office.
The Miami branch office has a file server named Certkingdom -SR25 that hosts
critical documents. Certkingdom -SR25 is configured with a DHCP client reservation.
Certkingdom.com users from all three offices download documents from
Certkingdom -SR25.
One day Certkingdom.com users complain that they cannot access the documents on
Certkingdom -SR25. You discover that the DHCP server has failed. The DHCP server
is located at headquarters.
You have received instruction from the CIO to ensure that Certkingdom -SR25 is
available even if it is unable to obtain or renew a lease from the DHCP server.
How could you accomplish this task?

A. On the DHCP server, increase the DHCP lease period.
B. Configure alternate IP settings for Certkingdom -SR25 on the Alternate Configuration
tab of the Internet Protocol (TCP/IP) properties.
C. Configure the DHCP scope in the 169.254.0.1. – 169.254.255.254 range.
D. On the DHCP server, configure the DHCP 001 Resource Location Servers reservation
option for Certkingdom -SR25.

Answer: B

Explaination: Windows Server 2003 includes the Alternate Configuration feature.
The Windows Server 2003 servers can be configured to use an alternate static IP
configuration if a DHCP server is unavailable. When a DHCP client determines that
the DHCP server is unavailable, it will automatically change over and also configure
the TCP/IP stack with the static address information specified on the Alternate
Configuration tab of the Internet Protocol (TCP/IP) properties.
Incorrect Answers:
A: Increasing the lease period would result in DHCP clients requesting leases less
frequently, but won’t guarantee that Certkingdom -SR25 will be available when the DHCP
server is down.
C: Modifying the DHCP scope to the 169.254.0.1. – 169.254.255.254 range will still be
reliant on the DHCP server.
D: Configuring the DHCP 001 Resource Location Servers reservation option for
Certkingdom -SR25 on the DHCP server will not ensure that Certkingdom -SR25 will
receive an IP address or have the IP address renewed.

QUESTION 8:

You work as the network administrator at Certkingdom.com The Certkingdom.com
network consists of a single Active Directory domain named Certkingdom.com All
servers on the Certkingdom.com network run Windows Server 2003 and all client
computers run Windows XP Professional. The Certkingdom.com network contains a
server named Certkingdom -SR34. Certkingdom -SR34 is configured as a DHCP server
and has been authorized in Active Directory. The Telnet service has been installed
and started on Certkingdom -SR34.
One day Certkingdom.com users complain that they cannot access network resources.
Your investigations reveal that the DHCP Server service on Certkingdom -SR34 has
stopped. You install the administrative tools on a client computer named
Certkingdom -WS291 and log on to the computer. When you open the DHCP console
on Certkingdom -WS291 and attempt to connect to Certkingdom -SR34, you receive an
error message that states: “Cannot find the DHCP Server.” You then attempt to
ping Certkingdom -SR34 but fail.
How can you connect to the DHCP Server service on Certkingdom -SR34 by using the
DHCP console on Certkingdom -WS291?

A. Establish a Telnet session to Certkingdom -SR34 and then run the net start dhcp
command.
B. Establish a Telnet session to Certkingdom -SR34 and then run the net start dhcpserver
command.
C. Establish a Telnet session to Certkingdom -SR34 and then run the ipconfig /renew
command.
D. On Certkingdom -WS291, run the netsh dhcp server\\ Certkingdom -SR34 show server
command.

Answer: B

Explaination: You can start the DHCP Server service by executing the Net Start
Dhcpserver command at the command prompt.
Telnet is a protocol that enables an Internet user to log on to and enter commands on a
remote computer linked to the Internet, as if the user were using a text-based terminal
directly attached to that computer. Telnet is part of the TCP/IP suite of protocols. The
term telnet also refers to the software (client or server component) that implements this
protocol.
Given the fact that you can ping Certkingdom -SR34 you should then establish a Telnet
session to Certkingdom -SR34 and then run the appropriate command.

located in the perimeter network. Certkingdom -SR21 contains antivirus software
that checks for new virus definitions on Certkingdom -SR25 every hour. You can also
access Certkingdom -SR25 through a virus update Web page to perform manual
virus definition updates.
Certkingdom -SR03 suffers a catastrophic failure and is removed from the network.
Due to budgetary constraints, a replacement for Certkingdom -SR03 will only be
acquired in the next financial year. You need to redesign network addressing
scheme, and change the IP addresses for Certkingdom -SR01 to the addresses shown
in the Network Topology exhibit.
Certkingdom -SR02 contains the new host (A) resource records for
Certkingdom -SR01.
You receive reports about a new virus threat and want to protect the network
immediately by manually downloading the new virus definitions to
Certkingdom -SR21. you log on to Certkingdom -SR21 but discover that you cannot
access the virus update Web page on Certkingdom -SR25. The static TCP/IP
configuration on Certkingdom -SR21 uses Certkingdom -SR02 as the preferred DNS
server.
You confirm that Certkingdom -SR01 is configured properly. On Certkingdom -SR21,
you view the Internet Explorer LAN settings that are shown in the LAN Settings
exhibit.
What should you do to allow Certkingdom -SR21 to connect to Certkingdom -SR25?

A. At a command prompt on Certkingdom -SR21, run the ipconfig /flushdns command.
B. In the LAN settings of Internet Explorer on Certkingdom -SR21, select the
Automatically detect settings check box.
C. At a command prompt on Certkingdom -SR01, run the ipconfig / flushdns command.
D. At a command prompt on Certkingdom -SR01, run the ipconfig /registerdns command.

Answer: A

Explaination: Running the ipconfig /flushdns command will flush and reset the DNS
resolver cache which is necessary to allow connection. Run this command on
Certkingdom -SR21 to connect to Certkingdom -SR25.
Incorrect Answers:
B: Selecting the “Automatically detect settings” checkbox is not going to allow
Certkingdom -SR21 to connect to WWW.
C: The ipconfig /flushdns command flushes and resets the DNS resolver cache. This is
not what is necessary.
D: The ipconfig /registerdns command refreshes all DHCP leases and registers any related
DNS names. This option is available only on Windows 2000 and newer computers that
run the DHCP Client service. This is not going to allow Certkingdom -SR21 to connect to
WWW when it is run on Certkingdom -SR01.

QUESTION 11:

You work as the network administrator at Certkingdom.com The Certkingdom.com
network consists of a single Active Directory domain named Certkingdom.com All
servers on the Certkingdom.com network run Windows Server 2003 and all client
computers run Windows XP Professional. The Certkingdom.com network contains a
DHCP server named Certkingdom -SR15 that is configured with a single scope.
Certkingdom.com hires a new Sales manager named Andy Reid. You install a new client
computer named Certkingdom -WS291 for Andy Reid. You connect
Certkingdom -WS291 to the network by plugging the network cable into the network
adapter on Certkingdom -WS291 and attempt to connect to Certkingdom -SR25.
However, you cannot access any of the servers on the network. When you open a
command prompt on Certkingdom -WS291 and run the ipconfig /renew command,
you receive the following response.

You log on to a client computer named Certkingdom -WS292 and run the ipconfig
/renew command successfully.
What should you do to ensure that Certkingdom -WS291 can receive its IP address
configuration from the Certkingdom -SR25?

A. Restart the DHCP service on Certkingdom -SR25.
B. Restart Certkingdom -WS291.
C. Restart Certkingdom -SR25.
D. Add additional IP addresses to the scope on Certkingdom -SR25.

Answer: B

Explaination: It is probable that the TCP/IP stack has a problem because the
computer is unable to send a DHCP discover broadcast packet. This can happen
when you insert a network cable after the PC has been started. You should restart
the client PC to successfully obtain a new IP address.
Incorrect Answers:
A, C, D: This is unnecessary because Certkingdom -WS292 did obtain an IP address from
the DHCP server, thus indicating that the DHCP server configuration is not the issue.

QUESTION 12:

You work as the network administrator at Certkingdom.com The Certkingdom.com
network consists of a single Active Directory domain named Certkingdom.com All
servers on the Certkingdom.com network run Windows Server 2003 and all client
computers run Windows XP Professional. Certkingdom.com has its headquarters in
Chicago and branch offices in Dallas and Miami. The Certkingdom.com network
contains a DHCP server named Certkingdom -SR01. The relevant portion of the
network is shown in the following network diagram.

You work at headquarters. A Certkingdom.com employee named Andy Booth is one of
three employees that are relocated to headquarters from the Dallas office. Andy
Booth uses a portable client computer named Certkingdom -WS291. Andy Booth
complains that when he plugs Certkingdom -WS291 into the LAN connection in his
new cubicle, he cannot connect to network resources on the LAN or the Internet.
None of the other employees are experiencing the same problem.
When you run the ipconfig command from a command prompt on
Certkingdom -WS291, you see the output as shown in the exhibit.

What should you do to allow Certkingdom -WS291 to connect to network resources
on the LAN or the Internet?

A. Configure Certkingdom -WS291 with a subnet mask of 255.255.240.0.
B. Configure Certkingdom -WS291 with a default gateway of 192.168.3.12.
C. Configure Certkingdom -WS291 with a primary DNS suffix of Certkingdom.com
D. Configure Certkingdom -WS291 to automatically lease an IP address from
Certkingdom -SR01.

Answer: D

Explaination: The client computers on the subnet use DHCP to obtain their IP
configurations. Certkingdom -WS291 has a static IP address, and therefore cannot
obtain a valid IP configuration from the DHCP server.
Incorrect Answers:
A: By changing the subnet mask you will not ensure that Certkingdom -WS291 will
connect to other computers and the Internet.
B: Changing the default gateway will not enable Certkingdom -WS291 LAN connection.
Besides, 192.168.3.12 is the IP address of the DHCP server.
C: Adding a primary DNS suffix means that only domain names listed in that window
will be tried for resolution purposes. Both the connection-specific and primary DNS
suffix are ignored.

QUESTION 13:

You work as the network administrator at Certkingdom.com The Certkingdom.com
network consists of a single Active Directory domain named Certkingdom.com All
servers on the Certkingdom.com network run Windows Server 2003 and all client
computers run Windows 2000 Professional. Certkingdom.com has headquarters in
London and branch offices in Paris, Berlin, Milan, Madrid, Stockholm, Warsaw,
Minsk, and Athens. Each branch office has a server that provides DHCP Server
services and between two to twenty client computers. A client computer in each
branch office is configured with a shared dial-up connection. You work at
headquarters.
The Berlin branch office has only two client computers named Certkingdom -WS291
and Certkingdom -WS292. A Certkingdom.com user named Kara Lang works in the
Berlin office. One morning Kara Lang complains that the shared dial-up connection
on Certkingdom -WS291 is no longer working.
Your investigation reveals that Certkingdom -WS292 can connect to shared folders
on Certkingdom -WS291 and that Certkingdom -WS291 can connect to the network at
headquarters. However, Certkingdom -WS292 cannot connect to resources on the
network at headquarters.
What should you do to ensure that both Certkingdom -WS291 and
Certkingdom -WS292 can connect to resources on the network at headquarters?

A. Reconfigure Internet Connection Sharing on Certkingdom -WS291.
B. Configure the shared dial-up connection on Certkingdom -WS291 so that automatic
dialog is enabled.
C. Configure Certkingdom -WS292 to receive an IP lease from a DHCP server.
D. Configure Certkingdom -WS292 to use Certkingdom -WS291 for DNS name resolution.

Answer: C.

Explaination: The problem is most likely caused by an incorrect or non-existent
default gateway setting on Certkingdom -WS292. If you configure
Certkingdom -WS292 to use DHCP to obtain IP addressing information,
Certkingdom -WS292 will receive the correct settings from the ICS service on
Certkingdom -WS291.
Incorrect Answers:
A: The question refers to a shared dial-up connection on Certkingdom -WS291 not
working. If the dial-up connection is shared, then Internet Connection Sharing is enabled
already.
B: The question states that Certkingdom -WS291 automatically connects to the network at
the main office whenever the user on Certkingdom -WS291 attempts to access resources
located on the main office network. This indicates that automatic dial-up is already
configured.
D: Certkingdom -WS291 is not a DNS server. The ICS service has a DNS proxy that
would pass DNS requests to whichever DNS server Certkingdom -WS291 is using.

QUESTION 14:

You work as the network administrator at Certkingdom.com The Certkingdom.com
network consists of a single Active Directory domain named Certkingdom.com All
servers on the Certkingdom.com network run Windows Server 2003 and all client
computers run Windows NT Workstation 4.0. The network contains 2,500 client
computers that are configured with static IP addresses.
Certkingdom.com issues a new network policy that requires all network computers to
have dynamically assigned IP configurations. You enable the DHCP Server service
on a member server named Certkingdom -SR25. Three network support technicians
have been instructed to configure the IP properties on all client computers to
receive a DHCP lease from Certkingdom -SR25.
It is estimated that the change over will take two weeks to complete. You need to
ensure that the DHCP server will not lease an IP address that is statically
configured on a computer that the network support technicians have not yet seen to.
What should you do?

A. On Certkingdom -SR25, configure Conflict detection attempts to 1.
B. On Certkingdom -SR25, configure Conflict detection attempts to 3.
C. On Certkingdom -SR25, configure client reservations for each client computer’s MAC
address.
D. On Certkingdom -SR25, activate and reconcile the scopes.

Answer: A

Explaination: When conflict detection attempts are set, the DHCP server uses the
Packet Internet Groper (ping) process to test available scope IP addresses before
including these addresses in DHCP lease offers to clients. A successful ping means
that the IP address is in use on the network. This results in the DHCP server not
offering to lease the address to a client.
If the ping request fails and times out, it indicates that the IP address is not in use on the
network. In this case, the DHCP server offers to lease the address to a client. Each
additional conflict detection attempt delays the DHCP server response by a second while
waiting for the ping request to time out. This in turn increases the load on the server. A
value of no greater than two (2) is recommended for ping attempts.
Incorrect Answers:
B: Due to the latency involved in ping attempts, the higher the conflict detection value is
set, the longer the lease process will be for every client that uses the DHCP server.
C: Configuring client reservations for each client computer MAC address will involve a
physical visit to each and every client computer if you do not ping it successfully.
D: The scope would already be activated in this scenario.

QUESTION 15:

You work as the network administrator at Certkingdom.com The Certkingdom.com
network consists of a single Active Directory domain named Certkingdom.com All
servers on the Certkingdom.com network run Windows Server 2003 and client
computers run Windows XP Professional, Windows 2000 Professional, or Windows
NT Workstation. All client computers are configured with default settings.
The Certkingdom.com network contains a server named Certkingdom -SR31 that
functions as a DHCP and DNS server, and a server named Certkingdom -SR38 that
contains antivirus server software. All DNS zones on Certkingdom -SR31 are enabled
for DNS dynamic updates. The computer account for each client computer is the
owner of its own DNS host record. No other server provides DNS services.
What must you do to ensure that Certkingdom -SR38 can contact client computers by
using fully qualified domain names (FQDNs) to propagate virus definition updates?

A. On Certkingdom -SR31, modify the Dynamically update DNS A and PTR records only
if requested by the DHCP clients option.
B. On Certkingdom -SR38, modify the Always dynamically update DNS A and PTR
records option.
C. On Certkingdom -SR31, modify the Discard A and PTR records when lease is deleted
option.
D. On Certkingdom -SR31, modify the Dynamically update DNS A and PTR records for
DHCP clients that do not request dynamic updates (for example, clients running
Windows NT 4.0) option.

Answer: D

Explaination: Dynamically Update DNS A And PTR Records For DHCP Clients That
Do Not Request
Updates – This checkbox lets you handle these older clients graciously by making the
updates using a separate mechanism. When checking this check box you will ensure that
Certkingdom -SR38can resolve FQDNs for all client computers on the network under the
given circumstances and the role that Certkingdom -SR31 plays.
Incorrect Answers:
A: Dynamically Update DNS A And PTR Records Only If Requested By The DHCP
Clients – This radio button (which is on by default) tells the DHCP server to register the
update only if the DHCP client asks for DNS registration. When this button is active,
DHCP clients that aren’t hip to DDNS won’t have their DNS records updated. However,
Windows 2000, XP, and Server 2003 DHCP clients are smart enough to ask for the
updates.
B: Always Dynamically Update DNS A And PTR Records – This radio button forces the
DHCP server to register any client to which it issues a lease. This setting may add DNS
registrations for DHCP-enabled devices that don’t really need them, like printer servers;
however, it allows other clients (like Mac OS, Windows NT, and Linux machines) to
have their DNS information automatically updated. This is not what is required.
C: Discard A And PTR Records When Lease Is Deleted – When a DHCP lease expires,
what should happen to the DNS registration? Obviously, it would be nice if the DNS
record associated with a lease vanished when the lease expired; when this checkbox is
checked (as it is by default), that’s exactly what happens. If you uncheck this box, your
DNS will contain entries for expired leases that are no longer valid; when a particular IP
address is reissued on a new lease, the DNS will be updated, but in between leases you’ll
have incorrect data in your DNS-always something to avoid.

Facebook Help Center Community Forum overrun with spam

Spammers have attacked the Facebook Help Center Community Forum over the Thanksgiving holiday weekend in the US. Most of the spam consists of links for live streaming American sporting events.

The Facebook Help Center’s page for asking questions about various help topics has been overrun with spam. All 22 sections of the Community Forum, as well as each of their subsections, have been attacked by spammers.

There are multiple Facebook accounts being used in the attack: some are asking questions and others are answering them. It’s not yet clear if these are bogus accounts created for just this purpose or if the perpetrators have compromised already-existing Facebook accounts.

The spammers are trying to lure users with the usual nonsense: most are links for streaming live sports matches (boxing, football, hockey, and so on), but the usual weight loss offers are also present. Some of them are just text, but most include a link to a third-party website.

Almost all of the links lead to a webpage asking you for your e-mail address, although some just take you to a bogus website with ads. It doesn’t appear any of these webpages contain malware, but spammers can always change where the links redirect you to. Do not click on any of these links.

It’s possible the spammers are taking advantage of the Thanksgiving holiday weekend in the US. I’m not sure whether more users check out the Community Help Topics during this time, but it’s very likely Facebook has fewer staff working to get rid of threats like this one.

This attack has rendered the self-help support community effectively useless. Legitimate questions are being pushed down towards the bottom; on most of the sections, the first page only contains spam. I have contacted Facebook with this issue and will update you if I hear back.

Update: “Protecting the people who use Facebook from spam and malicious content is a top priority for us, and we are always working to improve our systems to isolate and remove material that violates our terms,” a Facebook spokesperson said in a statement. “Recently, our Help Center Community Forum experienced an increase in spam claiming to offer streaming video of American sporting events. We are taking steps to address the issue and encourage people to protect themselves by never clicking on strange or suspicious links.”

CompTIA Hardware Support Multimedia Certification Courses - The Inside Track

CompTIA A+ computer training covers four specialised areas - you'll have to qualify in two of these areas to reach the level of competent in A+. This is why, many training establishments limit their course to 2 of the 4 sectors. We think this is selling you short - yes you'll have qualified, but knowledge of every section will prepare you more fully for when you're in industry, where you'll need a more comprehensive understanding. So that's why you should train in everything.

Comptia A+ Training, Comptia A+ certification

Best comptia A+ Training, Comptia A+ Certification at Certkingdom.com



A+ computer training courses cover diagnostics and fault finding - via hands on and remote access, as well as building computers and repairing them and working in antistatic conditions. If you're considering being the kind of individual who is a member of a large organisation - in network support, add Network+ to your CompTIA A+, or consider the Microsoft networking route (MCSA - MCSE) to give you a better comprehension of how networks work.

The perhaps intimidating chore of finding your first job can be eased by some companies, via a Job Placement Assistance programme. But don't place too much emphasis on it - it's quite easy for their marketing department to overstate it's need. Ultimately, the still growing need for IT personnel in the United Kingdom is what will make you attractive to employers.

You would ideally have help and assistance with preparing a CV and getting interviews though; also we would encourage all students to get their CV updated right at the beginning of their training - don't procrastinate and leave it for when you're ready to start work. A good number of junior support roles are offered to people who are in the process of training and haven't even passed a single exam yet. This will at the very least get you on your way. If it's important to you to find work near your home, then you'll probably find that a local IT focused recruitment consultancy might work much better for you than a national service, for they are much more inclined to have insider knowledge of what's available near you.

A slight frustration for a number of course providers is how hard men and women are focused on studying to pass exams, but how little effort that student will then put into getting the role they've studied for. Get out there and hustle - you might find it's fun.

A knowledgeable and specialised advisor (as opposed to a salesman) will talk through your current situation. There is no other way of working out your starting level of study. With some real-world experience or qualifications, you may find that your starting point is very different to someone completely new. If this is going to be your first effort at an IT exam then you should consider whether to start out with some basic Microsoft package and Windows skills first.

Quite often, students have issues with a single training area which is often not even considered: The way the training is divided into chunks and physically delivered to you. Drop-shipping your training elements one stage at a time, as you pass each exam is the usual method of releasing your program. Of course, this sounds sensible, but you must understand the following: How would they react if you didn't complete each and every module at the proposed pace? Often the staged order won't fit you as well as another different route may.

To avoid any potential future issues, many trainees now want to make sure that every element of their training is sent immediately, and not in a piecemeal fashion. That means it's down to you how fast or slow and in what order you'd like to work.

How LAN problems can impact on your firewalls

Last week seems to have been a firewall issue week for me. I worked on incidents in two large networks where problems on the LAN managed to bring down firewalls at the edge of the network. Firewalls have come a long way since the original stateless varieties, which were little more than a collection of access control lists. These were superseded by stateful firewalls which kept track of the state of network connections. Modern firewalls are now application aware, you can do things like block access to certain applications or prevent users from using applications like Bittorrent.

MCTS Certification, MCITP Certification

Best Avaya Certification Training and Avaya Exams Training and more Cisco exams log in to examkingdom.com



However, these firewalls don't come without their problems. They require lots of computing power to analyze and filter applications as they pass through. On some networks it can be a challenge getting the right balance of application awareness and traffic throughput. The more features you enable, the more stressed your firewall becomes. A lot of firewalls are priced on throughput: the greater the throughput, the greater the price. As a result of this, I see some networks with firewalls that are just about coping due to the costs involved of upgrading to the next model.

One incident I worked on last week was with an Internet service provider (ISP). A couple of their corporate firewalls, which linked their staff networks to the Internet, were resetting themselves. They suspected a resource issue on the firewalls and installed extra memory, but this seemed to make the problem worse. We discovered the source of the problem by looking at the network traffic going from the network core to the firewalls.

We found that large volumes of syslog traffic was being routed to an external IP address. This was unusual as syslog is normally used for managing local networks. We looked at the external IP addresses and saw that they were from an IP range that was once owned by the ISP. They sold it off and updated routing tables. However, nobody checked if any remaining systems were exporting data to this old subnet. Once routing tables were updated the syslog traffic was now sent out via their firewall. This caused an overload and the firewalls reset themselves.

It's an interesting problem caused by the lack of IPV4 address space. A block of addresses is very valuable. For example, earlier this year Microsoft paid $7.5 million to purchase a block of 666,624 IPv4 addresses. If you are looking to change IP addressing on your network, make sure you have monitoring in place so that you can identify what is using the IP addresses and for what reason.

The second incident I looked at involved a large university in Scotland. The connection rate limit on their main firewalls was peaking. This resulted in complaints from network users that connections were dropping or that downloading and uploading was slow.

Networks within educational campuses are typically more open than they would be in a corporate environment. This means that even things like what's on the TV schedules can affect network performance. Applications like Bittorrent can generate large numbers of connections as it downloads small pieces of data from lots of other clients on the Bittorrent network. In the case of this university network, users on their WiFi networks were tunnelling Bittorrent over TCP port 80. This resulted in large amounts of traffic and connections. The firewall rules were updated to only allow 80 parallel connections per IP address and the firewalls stabilized.

I do like the way application aware firewalls are evolving, more awareness of traffic coupled with clever management interfaces. However, no matter what firewall you choose you should be able to see what is going in and out of your network perimeter. Try and do this independently of the firewall, no point in trying to switch on logging or extra diagnostics if it's already stressed out. Knowing what is going in and out of your network can also help prevent network breaches.

Physicians using tablets to treat patients

Within the next year, almost half of all doctors will be using tablets and other mobile devices to perform everyday tasks, such as accessing patient information in electronic medical records (EMRs), according to the survey by the Computing Technology Industry Association (CompTIA), a nonprofit group.

MCTS Certification, MCITP Certification

Microsoft Commptia A+ Training , Comptia A+ Certification and over 2000+
Exams with Life Time Access Membership at http://www.actualkey.com


Today, a quarter of healthcare providers surveyed say they're using tablets in their practice. Another 21% indicated they expect to do so within a year.

CompTIA's Third Annual Healthcare IT Insights and Opportunities study was based on two seperate online surveys: One focused on 350 doctors, dentists and other healthcare providers or administrators; the other polled 400 IT firms with healthcare IT practices. Both were conducted in late July and early August.

The study shows that more than half of healthcare professionals currently use a smartphone for work, and about a third use their smartphones or tablets to access EMR systems. Another 20% expect to start mobile usage with EMRs within the next year.

The U.S. government is pressing all medical facilities to roll out EHRs by 2016, but the going has been slow so far. By the end of next year, 58% of small physician practices are expected to have EHR systems in place.

By 2014, the federal government wants more than half of all healthcare facilities to use EHRs.

Facilities that roll out the systems -- and prove their meaningful use, according to federal standards -- can receive tens of thousands of dollars in reimbursement money under the American Recovery and Reinvestment Act of 2009. Some facilities, depending on their size, could get millions.

EHRs are also expected to promote the use of standardized medical practices.

CompTIA's survey also showed EMR system adoption is on the rise, with 38% of healthcare providers indicating they have a comprehensive system in place and 17% saying they have a partial system or module. Sixty-one percent of the EMR said they're generally satisfied with their comprehensive systems.

"That's a respectable figure, but one that also indicates there's room for improvement in areas such as greater ease of use; better interoperability with other systems; faster speeds; improved remote access and mobility features; and more training," CompTIA said.

Doctors have reported feeling like data-entry clerks when typing their own notes into EMR systems. Others are unfamiliar with the technology and see it as yet one more learning curve to conquer in their jobs.

"We're a teaching hospital, so on one end of the spectrum we have residents born with a computer in their hand and so they look at this as an opportunity to move forward; on the other side of the spectrum are the physicians [who] are in their 60s and the very idea of signing onto a computer is a big question mark to them," said Bill Fawns, director of IT services at Kern Medical Center in Bakersfield, Calif.

Late last year, Kern Medical Center, a 222-bed acute-care teaching hospital, deployed an OpenVista EMR system from Medsphere Systems Corp.

"As mobile devices and applications have become more user-friendly, affordable and powerful, the appeal to businesses of all types, including healthcare providers, has grown exponentially," Tim Herbert, vice president of research at CompTIA, said in a statement.

The survey also touched on the adoption of cloud computing in the healthcare industry. The results showed cloud computing is clearly in its early stages, with 57% indicating they were not very familiar with the technology and just 5% stating they were using cloud services.

"It's worth noting, though, that some healthcare providers are likely using cloud-based applications, like software-as-a-service, and not thinking of it as cloud computing," the report stated.

The potential for its growth is strong. A key component of EMR meaningful use standards is the ability to share information, either through proprietary networks or through regional Health Information Exchanges, which will include many of the elements of cloud computing.

Adoption of telemedicine, where physicians consult with patients with teleconferencing, is still a ways off, the report said. Recent studies have shown that patients can be just as effectively treated through telemedicine as through traditional in-person visits. In fact, studies have shown telemedicine actually improves patient-physician communication.

Hoewever, just 14% of healthcare professionals reported actively following news and trends in telemedicine, according to CompTIA's survey.

Those surveyed indicated they saw the greatest benefits of telemedicine in the areas of continuing medical education (61%), specialist referral services (44%) and patient consultations (37%). Only one in 10 healthcare providers surveyed say they intend to use video conferencing for patient interaction within the next 12 months.

The next generation of live support chat software

Although it may be hard to believe, life support software that allows customers and browsers to chat to each other over the web has actually been around for almost 15 years now. The main difference is the fact that now more companies are using it which has helped raise the profile of live support chat software a great deal as business people are realizing that it is still one of the top tools for communicating with consumers and offering them instant support as well as the satisfaction of knowing they are working with a real agent.

Cisco CCNA Training, Cisco CCNA Certification

Best HP Certification Training and HP Exams Training and more Cisco exams log in to Certkingdom.com



In fact, live support software is so popular that the US Army even uses a live support chat software device in order to help answer potential recruits’ questions as well as military families that are looking for help with reassignment, deployment, and assistance questions. With this much success backing live support chat software, it should come as little surprise then that there is now a new generation of live support chat software that is slowly rolling out helping to make the software much easier to utilise from a business point of view and much more pleasing to use from a customer’s point of view.


The major problems with live support software right now is that in some instances it still lacks the human touch despite the fact that humans are actually the one’s doing the chatting. This is due to the fact that most companies want to optimise the agents that they hire to staff their live support chat software, therefore they have agents that handle five or more conversations at a time which can lead to inaccuracies in grammar and delayed responses. This can leave some more picky browsers disgruntled with live support software and the entire experience.

However, the new generation of live support chat software aims to solve this by cutting out live agents altogether thereby somewhat making the name ironic, but getting the job done in a much more efficient manner. In the place of live agents on the other side of the live support software is a virtual employer that relies on virtual intelligence to answer questions and get the job done with the programming to make sure that the customer gets perfect grammar every time along with a rapid fast response. Surprisingly enough, this software seems to be catching on as those who use live support chat software with this option seem quite pleased with the results.


From a business point of view, the use of a virtual agent that is able to be programmed to respond like a live human agent is obvious. The average chat over a live support software service will last 18 minutes, out of which five minutes are spent by the customer waiting for the next available representative. However, a virtual agent can respond right away eliminating the need for any wait and allowing the live support chat software to live up to its rep as an instant form of customer service.

Next, continuing the business point of view, bear in mind that you do not have to pay the virtual agent anything for its time, reducing the costs of actual hiring agents to staff your live support software or attempting to man it on your own. For those who receive a high volume of chat requests, this is an excellent choice given the average cost of a chat is considered to be five dollars per session all things considered. Plus, as always, if the virtual agent gets stuck the live chat can be turned over to a real human so that you do have to worry about losing a customer but can easily streamline the live support software service in most cases on your website cheaply and effectively.

QUESTION 1
You work as a network administrator for Certkingdom.com. The Certkingdom.com network consists of a single
Active Directory domain named Certkingdom.com. There are currently 120 Web servers running Windows
2000 Server and are contained in an Organizational Unit (OU) named ABC_WebServers
Certkingdom.com management took a decision to uABCrade all Web servers to Windows Server 2003.
You disable all services on the Web servers that are not required. After running the IIS Lockdown
Wizard on a recently deployed web server, you discover that services such as NNTP that are not
required are still enabled on the Web server.
How can you ensure that the services that are not required are forever disabled on the Web
servers without affecting the other servers on the network? Choose two.

A. Set up a GPO that will change the startup type for the services to Automatic.
B. By linking the GPO to the ABC_WebServers OU.
C. Set up a GPO with the Hisecws.inf security template imported into the GPO.
D. By linking the GPO to the domain.
E. Set up a GPO in order to set the startup type of the redundant services to Disabled.
F. By linking the GPO to the Domain Controllers OU.
G. Set up a GPO in order to apply a startup script to stop the redundant services.

Answer: B,E

Explanation: Windows Server 2003 installs a great many services with the operating system, and
configures a number of with the Automatic startup type, so that these services load automatically
when the system starts. Many of these services are not needed in a typical member server
configuration, and it is a good idea to disable the ones that the computer does not need. Services
are programs that run continuously in the background, waiting for another application to call on
them. Instead of controlling the services manually, using the Services console, you can configure
service parameters as part of a GPO. Applying the GPO to a container object causes the services
on all the computers in that container to be reconfigured. To configure service parameters in the
Group Policy Object Editor console, you browse to the Computer Configuration\Windows
Settings\Security Settings\System Services container and select the policies corresponding to the
services you want to control.

QUESTION 2
You are working as the administrator at Certkingdom.com. Certkingdom.com has headquarters in London and
branch offices in Berlin, Minsk, and Athens. The Berlin, Minsk and Athens branch offices each
have a Windows Server 2003 domain controller named ABC-DC01, ABC-DC02 and ABC-DC03
respectively. All client computers on the Certkingdom.com network run Windows XP Professional.
One morning users at the Minsk branch office complain that they are experiencing intermittent
problems authenticating to the domain. You believe that a specific client computer is the cause of
this issue and so need to discover the IP address client computer.
How would you capture authentication event details on ABC-DC02 in the Minsk branch office?

A. By monitoring the logon events using the SysMon utility.
B. By recording the connections to the NETLOGON share using the SysMon utility.
C. By recording the authentication events with the NetMon utility.
D. By monitoring the authentication events using the Performance and Reliability Monitor.

Answer: C

Explanation: The question states that you need to find out the IP address of the client computer
that is the source of the problem. Using Network Monitor to capture traffic is the only way to do
this.

QUESTION 3
You are working as the administrator at Certkingdom.com. Part of you job description includes the
deployment of applications on the Certkingdom.com network. To this end you operate by testing new
application deployment in a test environment prior to deployment on the production network.
The new application that should be tested requires 2 processors and 3 GB of RAM to run
successfully. Further requirements of this application also include shared folders and installation of
software on client computers. You install the application on a Windows Server 2003 Web Edition
computer and install the application on 30 test client computers.
During routine monitoring you discover that only a small amount of client computers are able to
connect and run the application. You decide to turn off the computers that are able to make a
connection and discover that the computers that failed to open the application can now run the
application.
How would you ensure that all client computers can connect to the server and run the application?

A. By running a second instance of the application on the server.
B. By increasing the Request Queue Limit on the Default Application Pool.
C. By modifying the test server operating system to Window Server 2003 Standard Edition.
D. By increasing the amount of RAM in the server to 4GB.

Answer: C

Explanation: Although Windows Server 2003 Web Edition supports up to 2GB of RAM, it
reserves 1GB of it for the operating system; only 1GB of RAM is available for the application.
Therefore, we need to install Window Server 2003 Standard Edition or Enterprise Edition to
support enough RAM.


QUESTION 4
You are an Enterprise administrator for Certkingdom.com. All servers on the corporate network run
Windows Server 2003 and all client computers run Windows XP.
The network contains a server named ABC-SR01 that has Routing and Remote Access service
and a modem installed which connects to an external phone line.
A partner company uses a dial-up connection to connect to ABC-SR01 to upload product and
inventory information. This connection happens between the hours of 1:00am and 2:00am every
morning and uses a domain user account to log on to ABC-SR01.
You have been asked by the security officer to secure the connection.
How can you ensure that the dial-up connection is initiated only from the partner company and that
access is restricted to just ABC-SR01? Choose three.

A. Set up the log on hours restriction for the domain user account to restrict the log on to between
the hours of 1:00am and 2:00am.
B. Set up a local user account on ABC-SR01. Have the dial-up connection configured to log on
with this account.
C. Set up the remote access policy on ABC-SR01 to allow the connection for the specified user
account between the hours of 1:00am and 2:00am.
D. Set up the remote access policy with the Verify Caller ID option to only allow calling from the
phone number of the partner company modem.
E. Set up the remote access policy to allow access to the domain user account only.

Answer: B,C,D

Explanation: To allow only the minimum amount of access to the network, ensure that only the
partner's application can connect to your network over the dial-up connection, you need to first
create a local account named on ABC-SR01. You need to then add this account to the local Users
group and direct the partner company to use this account for remote access.
You can use a local account to provide remote access to users. The user account for a standalone
server or server running Active Directory contains a set of dial-in properties that are used
when allowing or denying a connection attempt made by a user. You can use the Remote Access
Permission (Dial-in or VPN) property to set remote access permission to be explicitly allowed,
denied, or determined through remote access policies.
Next, you need to configure a remote access policy on ABC-SR01 to allow the connection for only
the specified user account between 1 AM and 2 AM.
In all cases, remote access policies are used to authorize the connection attempt. If access is
explicitly allowed, remote access policy conditions, user account properties, or profile properties
can still deny the connection attempt.
You need to then configure the policy to allow only the specific calling station identifier of the
partner company's computer. When the Verify Caller ID property is enabled, the server verifies the
caller's phone number. If the caller's phone number does not match the configured phone number,
the connection attempt is denied.

QUESTION 5
You are an Enterprise administrator for Certkingdom.com. The company consists of an Active Directory
domain called ad.Certkingdom.com. All servers on the corporate network run Windows Server 2003. At
present there is no provision was made for Internet connectivity.
A server named ABC2 has the DNS server service role installed. The DNS zones on ABC2 are
shown below:



The corporate network also contains a UNIX-based DNS A server named ABC-SR25 hosts a
separate DNS zone on a separate network called Certkingdom.com. ABC-SR25 provides DNS services to
the UNIX-based computers and is configured to run the latest version of BIND and the Certkingdom.com
contains publicly accessible Web and mail servers.
The company has a security policy set, according to which, the resources located on the internal
network and the internal network's DNS namespace should never be exposed to the Internet.
Besides this, according to the current network design, ABC-SR25 must attempt to resolve any
name resolution requests before sending them to name servers on the Internet.
The company plans to allow users of the internal network to access Internet-based resources. To
implement the security policy of the company, you decided to send all name resolution requests
for Internet-based resources from internal network computers through ABC2. You thus need to
devise a name resolution strategy for Internet access as well as configuring ABC2 so that it will
comply with the set criteria and restrictions.
Which two of the following options should you perform?

A. Have the Cache.dns file copied from ABC2 to ABC-SR25.
B. Have the root zone removed from ABC2.
C. ABC2 should be set up to forward requests to ABC-SR25.
D. Install Services for Unix on ABC2.
E. The root zone should be configured on ABC-SR25.
F. Disable recursion on ABC-SR25.

Answer: B,C

Explanation: To plan a name resolution strategy for Internet access and configure ABC2 so that it
sends all name resolution requests for Internet-based resources from internal network computers
through ABC2, you need to delete the root zone from ABC2. Configure ABC2 to forward requests
to ABC-SR25
A DNS server running Windows Server 2003 follows specific steps in its name-resolution process.
A DNS server first queries its cache, it checks its zone records, it sends requests to forwarders,
and then it tries resolution by using root servers.
The root zone indicates to your DNS server that it is a root Internet server. Therefore, your DNS
server does not use forwarders or root hints in the name-resolution process. Deleting the root
zone from ABC2 will allow you to first send requests to ABC2 and then forward requests to ABCSR25
by configuring forward lookup zone. If the root zone is configured, you will not be able to use
the DNS server to resolve queries for hosts in zones for which the server is not authoritative and
will not be able to use this DNS Server to resolve queries on the Internet.

Cisco created the game for the company’s network certification site, the Learning Network. That site features a number of computer games such as The Cisco Mind Share Game that let you play and learn the content of the CCENT/ CCNA exam. If that’s possible.

From the company’s Web site: “In myPlanNet v1.0, we included some events that present players with challenges or opportunities. Think of these like Chance or Community Chest cards in Monopoly. Events include things like threats from competitors, initiating marketing programs, and even coping with disasters. These events may affect cash amounts, population size, happiness, service adoption, among other things. We admit that what's in there is a little basic, so there's lots of room for improvement. That's where you come in.”

The game begins when you download a 40mb file to a Windows only machine. On the myPlanNet site the company says it has no plans right now to offer a Linux or other version of the game.

It's a startling technology that uses a small projector and a depth-sensitive camera to project a user interface onto a wall, your hand, or anything at all and let a user interact with it.

Now you don't even need to go through the trouble of taking your phone out of your pocket to dial a number.

(The drawback is that you have to wear a big camera pack on your shoulder, making the technology vastly more cumbersome than an actual touchscreen.)
