You are a professional level SQL Sever 2008 Database Administrator.
A solution will be implemented to have hardware configurations obtained. The hardware configuration obtained should include the number of processors on a computer and the processor type of all SQL Server 2008 computers. The requirements listed below should be satisfied by the solution. The solution should be hosted on the central computer. And the hardware configurations for multiple servers should be verified bythe solution.
A technology should be selected to satisfy the requirements, and the least amount of development effort should be utilized.
Which action should you perform to finish the task?

• A.To finish the task, you should utilize the ExecuteSql function to define policies based on conditions.

You are a professional level SQL Sever 2008 Database Administrator.
A large financial database is hosted by the instance. The backup strategies listed below are contained by
the database:
First, the performance of a full database backup is implemented once a week.
Secondly, the performance of a differential backup is implemented every day.
Thirdly, the performance of a transaction log backup is implemented every hour.
An end-of-year batch process should be implemented, and the process takes two hours to run.
About five percent of data within the database will be changed by the batch process.
Since you are the technical support, you are required to make sure that the batch operation can be rolled
back
in the shortest time, if the batch process is not approved by the Finance department.
What should you do first before start the batch process?

• A.You should create a database snapshot.
• B.You should record the time before the batch operation. And then you should perform a transaction log
• C.You should create a marked transaction. And then you should perform a transaction log backup.
• D.You should perform a differential backup.

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

You are designing a database solution by using SQL Server 2008.
The database has a large number of tables that have columns that contain sensitive data. The sensitive data must be protected.
You need to choose an encryption strategy that has the minimum effect on the performance of the server.
What should you do? (More than one answer choice may achieve the goal. Select the BEST answer.)

• A.Use Bitlocker Encryption.
• B.Use Cell-Level Encryption.
• C.Use Encrypting File System.
• D.Use Transparent Data Encryption (TDE).

You administer a SQL Server 2008 instance. You plan to design a high-availability solution by using database mirroring.
The current application includes programming logic that will retry transactions if a failover occurs.
You need to configure a strategy that will provide the minimum amount of latency for committed transactions.
What should you do?

• A.Pause database mirroring.
• B.Configure automatic failover role switching.
• C.Configure forced service role switching.
• D.Configure manual failover role switching.
