Microsoft PRO:MS SQL Serv 08,Design,Optimize, and Maintain DB Admin Solu Sample Questions:

1. You are a professional level SQL Sever 2008 Database Administrator.
An instance runs on a computer, and the computer has eight quad-core processors and 128-GB RAM. The instance is utilized by four different applications. Not only a low number of CXPACKET waits but also a large number of lazy writer waits are experienced by the instance. The performance of the instance should be optimized.
Which action will you perform to accomplish the goal?

A) To accomplish the goal, software non-uniform memory access (soft-NUMA) should be configured.
B) To accomplish the goal, the Windows System Resource Manager should be configured.
C) To accomplish the goal, an increase should be configured in the maximum degree of parallelism option.
D) To accomplish the goal, the Resource Governor should be configured.

2. You administer a SQL Server 2008 instance that hosts a large database.
The database experiences high volumes of queries and transactions that are processor-intensive. You plan to implement an incremental backup strategy for the database. You also plan to use backup compression.
You need to ensure that the backup jobs have a minimal effect on the performance of the server.
What should you do?

A) Use database snapshots.
B) Spread the database backup across multiple backup devices.
C) Use the Resource Governor.
D) Reconfigure the Affinity I/O Mask configuration option.

3. You administer a SQL Server 2008 infrastructure.
An instance hosts a business-critical database that must be continuously available to the users without data loss. The database includes Filestream data.
You need to implement a high-availability solution for the site.
Which solution should you use?

A) Failover clustering
B) Synchronous database mirroring with a witness server
C) Asynchronous database mirroring
D) Database snapshot

4. You deploy a new database application to a SQL Server 2008 instance on a server that has 4 processor
cores and 64 GB of RAM. The application uses partitioned tables.
During testing, deadlocks occasionally occur on queries that are attempting to read data.
You find out that the deadlocks are related to the table partitions.
You need to ensure that the application executes without deadlocks for the read queries.
You also need to ensure that dirty reads do not occur.
What should you do? (More than one answer choice may achieve the goal. Select the BEST answer.)

A) Add additional database files to each partitioned table.
B) Disable partition-level lock escalation.
C) Move the clustered indexes for the partitioned tables to a separate filegroup.
D) Move each partitioned table to its own filegroup.

5. You are a professional level SQL Sever 2008 Database Administrator.
A database is hosted by the instance and the database is configured by utilizing high-safety mirroring operation mode along with a witness server. A memory failure is experienced by the witness server; therefore the server will be offline for five hours. The mirroring strategy should be reset to cut the risk of database unavailability to the least level.
Which action should you perform to finish the task?

A) To finish the task, database mirroring should be removed.
B) To finish the task, database mirroring should be paused.
C) To finish the task, asynchronous operating mode should be utilized.
D) To finish the task, the witness server should be moved from the mirroring session.
