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

Question #1
You administer a SQL Server 2008 instance that will host a new database application.
You plan to design the security requirements for the application. Each application user has a unique login to
the SQL Server 2008 server.
The application database contains stored procedures to execute stored procedures in the MSDB database.
The stored procedures in the MSDB database schedule SQLAgent jobs.
You need to ensure that the stored procedures in the MSDB database are executed by using the security
context of the application user.
What should you do?

A. Add each user to the db_dtsltduser database role in the MSDB database.
B. Configure the new database to use the TRUSTWORTHY option, and then add each user to the MSDB database.
C. Configure the MSDB database to use the TRUSTWORTHY option, and then add each user to the MSDB database.
D. Add each user to the public role in the MSDB database.

Question #2
You are a professional level SQL Sever 2008 Database Administrator.
The largest table in a database is partitioned into four equal-sized parts.
The first two partitions are seldom queried, while the third partition is regularly queried by several reports. Meanwhile, the fourth partition is heavily queried and regularly modified.
The disk space of the table should be cut to the least and the query performance should be with the least impact.
What will you do? (Choose more than one.)

A. PAGE compression should be enabled for the third partition.
B. ROW compression should be enabled for the last partition.
C. ROW compression should be enabled for the third partition.
D. PAGE compression should be enabled for the first two partitions.
E. PAGE compression should be enabled for the last partition.
F. ROW compression should be enabled for the first two partitions.

Question #3
You administer a SQL Server 2008 infrastructure.
Your company requires capacity planning information.
You need to design a long-term infrastructure monitoring strategy.
Which two tasks should you include in your design? (Each correct answer presents part of the solution.
Choose two.)

A. Backup all databases every day.
B. Clear the system log and the application log every hour.
C. Review system monitor counters on a regular basis.
D. Create a maintenance plan that rebuilds indexes every week.
E. Baseline the system before you deploy production databases.

Question #4
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. Configure forced service role switching.
B. Configure automatic failover role switching.
C. Configure manual failover role switching.
D. Pause database mirroring.

Question #5
You are planning to upgrade a database application that uses merge replication.
The table currently has a column type of UNIQUEIDENTIFIER and has a DEFAULT constratin that uses
the NEWID() function.
A new version of the application requires that the FILESTREAM datatype be added to a table in the
database.
The data type will be used to store binary files. Some of the files will be larger than 2 GB in size.
While testing the upgrade, you discover that replication fails on the articles that contain the FILESTREAM
data.
You find out that the failure occurs when a file object is larger than 2 GB.
You need to ensure that merge replication will continue to function after the upgrade.
You also need to ensure that replication occurs without errors and has the best performance.
What should you do? (More than one answer choice may achieve the goal. Select the BEST answer.)

A. Place the table that will contain the FILESTREAM data type on a separate filegroup.
B. Change the DEFAULT constraint to use the NEWSEQUENTIALID() function.
C. Drop and recreate the table that will use the FILESTREAM data type.
D. Use the sp_changemergearticle stored procedure and set the @stream_blob_columns option to true for the table that will use the FILESTREAM data type.
