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

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

2. You administer a SQL Server 2008 infrastructure. You plan to design an infrastructure for a new application.
The application has the following requirements:
Users can connect to an instance named SQLSERVER1.
SQLSERVER1 is linked to a server named SQLSERVER2.
SQLSERVER1 and SQLSERVER2 run on different computers.
The SQL Server instances use only Windows authentication.
You need to configure the infrastructure to ensure that the distributed queries are executed in the Windows security context of the login.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

A) Use the local computer account as a service account for SQLSERVER1 and SQLSERVER2.
B) Ensure that the two instances use the same Windows account for the Microsoft SQL Service. Create the link so that each account uses the current security context.
C) Configure all servers to use the Shared Memory network protocol.
D) Create a map for each SQL login from SQLSERVER1 to SQLSERVER2 and use the impersonate option.
E) Register a server principal name (SPN) for SQLSERVER1 and SQLSERVER2.

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

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

5. You administer a SQL Server 2008 infrastructure.
An instance contains a database that includes a large table named OrderDetails. The application queries
only execute
DML statements on the last three months data. Administrative audits are conducted monthly on data older
than three months.
You discover the following performance problems in the database. The performance of the application
queries against the
OrderDetail table is poor. The maintenance tasks against the database, including index defragmentation,
take a long time.
You need to resolve the performance problems without affecting the server performance.
What should you do?

A) Create an additional table named OrderDetailsHistory for data older than three months. Create a SQL Server Agent job that runs the following Transact-SQL statement every month. INSERT INTO OrderDetailsHistory SELECT * FROM OrderDetails WHERE DATEDIFF( m,OrderDate,GETDATE ()) > 3
B) Create an additional table named OrderDetailsHistory for data older than three months. Partition the OrderDetails and OrderDetailsHistory tables in two parts by using the OrderDatecolumn. Create a SQL Server Agent job that runs every month and uses the ALTER TABLE...SWITCH Transact-SQL statement to move data that is older than three months to the OrderDetailsHistory table.
C) Create an additional table named OrderDetailsHistory for data older than three months. Use the following Transact-SQL statement. CREATE TRIGGER trgMoveData ON OrderDetails AFTER INSERT AS INSERT INTO OrderDetailsHistory SELECT * FROM OrderDetails WHERE DATEDIFF( m,OrderDate,GETDATE ()) > 3
D) Create a database snapshot for the OrderDetails table every three months. Modify the queries to use the current snapshot.
