Customers are already managing more than 100,000 virtual machines using the software as part of an early access program, Satya Nadella, president of Microsoft's Server and Tools Business, said during a video conference about the news.

Using System Center, an organization can manage its internal private cloud as well as applications and services it is running in public clouds. This hybrid approach -- where a company may run an application in a public cloud but retain the corresponding database on a private cloud, for example -- is increasingly common.

System Center 2012 combines eight former products into one and addresses one common complaint customers have, said Brad Anderson, corporate vice president of Microsoft's Management and Security Division. "We hear a lot that licensing is complex," he said. System Center 2012 aims to simplify licensing by combining several former products into one and by offering just two different versions.

In addition, Microsoft bases its license on a slightly different model than its competitors, he said. Customers pay for System Center 2012 on a per-server basis, rather than a per-virtual machine basis. That can keep costs down for people who are running many virtual machines per server.

During the video conference about the release, Microsoft showcased a few companies that have already been using System Center. They include Luftansa, T. Rowe Price and Unilver. Those companies said that System Center 2012 has let them quickly expand their infrastructure and automate the management of their systems.

Microsoft says that using a tool like System Center can help organizations more efficiently manage their cloud environments. The company typically hears from customers who have full time IT administrators managing 30 to 40 servers. But Microsoft itself, which operates huge data centers to run services like Bing, Azure and Hotmail, finds that each of its IT workers, using System Center 2012, manages as many as 5,000 servers.

System Center 2012 has also expanded to allow IT administrators to manage non-Microsoft devices, including mobile phones. Rather than thinking of devices as being at the center of the management process, System Center 2012 puts the user in the middle, said Anderson. That means a manager can set policies for an employee that applies no matter what device the employee is using, including Android phones, iPhones or a variety of tablets.

The release candidate of System Center 2012 is available immediately. Provided users don't find any major bugs, the next step should be general availability of the software.

QUESTION 1
You work as a database administrator at Certkingdom.com. You are in the process of preparing the
deployment of a new database that will have 45 gigabytes storage space for the transaction log
file, and 280 gigabytes storage space for the database data file.
There are approximately six 120 GB disk drives available for the database in the storage array.
Certkingdom.com contains a RAID controller that supports RAID levels 0, 1, 5 and 10. The disks are on
the RAID controller. You have received an instruction from the CIO to make sure that the
transaction log’s write performance runs at optimum. The CIO has also instructed you to make
sure that in the event of a drive failure, the database and transaction log files are protected.
To achieve this goal, you decide to configure a storage solution.
Which of the following actions should you take?

A. You should consider using a RAID 1 volume as well as a RAID 5 volume in your storage configuration.
B. You should consider using a RAID 1 volume as well as a RAID 10 volume in your storage configuration.
C. You should consider using a RAID 3 volume as well as a RAID 5 volume in your storage configuration.
D. You should consider using a RAID 1 volume as well as a RAID 3 volume in your storage configuration.

Answer: A

Explanation:


QUESTION 2
You work as a database administrator at Certkingdom.com. Certkingdom.com has a database server named ABCDB04
with a SQL Server 2008 instance that includes an extensive mission-critical database that is
constantly being used ABC-DB04 has a quad-core motherboard with four CPUs.
When it is reported that ABC-DB04 often encounters CPU pressure, you receive an instruction
from management to make sure that the accessible CPU cycles are not exhausted by online index rebuilds.
Which of the following actions should you take?

A. You should make use of the affinity I/O mask option.
B. You should make use of the optimize for ad hoc workloads option.

Answer: D

Explanation:


QUESTION 3
You work as a database administrator at Certkingdom.com. Certkingdom.com has a database server named ABCDB01
with a SQL Server 2008 instance.
During routine monitoring on ABC-DB01, you discover that the amount of CXPACKET waits
experienced by the instance is low, while the amount of lazy writer waits is abundant.
You have been instructed to enhance the operation of the instance to ensure productivity.
Which of the following actions should you take?

A. You should consider setting up the Windows System Monitoring tool to better the performance.
B. You should consider setting up the Asynchronous database mirroring to better the performance.

QUESTION 4
You work as a database administrator at Certkingdom.com. Certkingdom.com has a database server named ABCDB01.
ABC-DB01 is configured with 4 quad-core processors, 80 gigabytes of RAM, and multiple
independent raid volumes.
You are in the process of using a transactional database on the instance. It is anticipated that the
transactional database will have a significant amount of INSERT, UPDATE, and DELETE
activities, which incorporates the creation of new tables.
You receive an instruction from management to minimize the contention in the storage allocation
structures so that database performance is optimized, and the disk bandwidth maximized.
Which of the following actions should you take?

A. You should consider enabling Server Auditing.
B. You should consider using multiple data files for the database.
C. You should consider using row-level compression.
D. You should consider using the checksum page verify option.

Answer: B
