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

2. You administer a SQL Server 2008 infrastructure.
You plan to design a maintenance strategy for a mission-critical database that includes a large table named Orders. The design plan includes index maintenance operations.
You must design the strategy after considering the following facts:
The Orders table in the database is constantly accessed.
New rows are frequently added to the Orders table.
The average fragmentation for the clustered index of the Orders table is less than 2 percent.
The Orders table includes a column of the xml data type.
You need to implement the strategy so that the performance of the queries on the table is optimized.
What should you do?

A) Drop the clustered index of the Orders table.
B) Rebuild the clustered index of the Orders table offline once a month.
C) Reorganize the clustered index of the Orders table by decreasing the fill factor.
D) Exclude the clustered index of the Orders table from scheduled reorganizing or rebuilding operations.

3. Your SQL Server 2008 database contains two tables named Customer and Order inside the Sales schema.
The Sales schema is defined as follows:
It has a stored procedure named SetCustomerStatus that reads from Order and modifies Customer.
It is owned by a user named SalesUser.
Another user named marketingUser wants to be able to call SetCustomerStatus and change the status of Customer.
You need to assign the least permission necessary to MarketingUser.
What should you do? (More than one answer choice may achieve the goal. Select the BEST answer.)

A) Set only Execute on SetCustomerStatus.
B) Perform the following tasks:
Set Select on Customer.
Set Update on Order.
C) Set only Take Ownership on ustomer and Order.
D) Perform the following tasks:
Set Execute on SetCustomerStatus.
Set Select on Customer.
Set Update on Order.

4. You administer a SQL Server 2008 instance.
The instance hosts a database that is used by a Web-based application. The application processes 15,000 transactions every minute. A table in the database contains a column that is used only by the application. This column stores sensitive data.
You need to store the sensitive data in the most secure manner possible.
You also need to ensure that you minimize the usage of memory space and processor time.
Which encryption type should you use?

A) Symmetric key encryption
B) Transparent data encryption
C) Certificate-based encryption
D) Asymmetric key encryption

5. You administer a SQL Server 2008 infrastructure.
You implement log shipping for several databases on three SQL Server instances. The logs are shipped to a fourth SQL Server instance. You plan a manual failover.
You need to ensure that the database applications use the secondary server after failover. You also need to ensure that users can access the most recent data.
Which three tasks should you perform? (Each correct answer presents part of the solution. Choose three.)

A) Redirect client computers to the secondary instance.
B) Back up all databases on the secondary instance.
C) Copy all log shipping network shares to the secondary instance.
D) Apply any unapplied transaction log backups in sequence to each secondary database by using the WITH RECOVERY option on the last log.
E) Back up the tail of the transaction log of primary databases by using the WITH NORECOVERY option.
