Microsoft 070-450 Exam Syllabus Topics:

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

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

2. You are designing a new SQL Server instance that will support a Web application.
The Web application is hosted on a Web farm that contains 32 nodes.
The server has 128 GB of memory and 16 processor cores. The application contains two databases and supports both online analytical processing (OLAP) and online transaction processing (OLTP) workloads.
When testing the application, you discover that some queries run extremely slow and some queries run very fast.
You need to ensure that the server processes database queries as fast as possible . What should you do? (More than one answer choice may achieve the goal. Select the BEST answer.)

A) Use SQL Profiler to identify queries that experience CXPACKET waits. Add (OPTION MAXDOP 1) to each query
B) Execute the following command on the server: exec_sp_configure 'maximum degree of parallelism', 8
C) Use SQL Profiler to identify queries that experience CXPACKET waits. Add (OPTION MAXDOP 8) to each query
D) Execute the following command on the server: exec_sp_configure 'maximum degree of parallelism', 1

3. You are a professional level SQL Sever 2008 Database.
A new database application is hosted by the instance. The security requirements should be designed for the application. A unique login to the SQL Server 2008 server is assigned to each application user. Stored procedures are included by the application database to execute stored procedures in the MSDB database. SQLAgent jobs are scheduled by the stored procedures in the MSDB database.
Since you are the technical support, you are required to confirm that the stored procedures in the MSDB database should be executed by utilizing the security context of the application user.
Which action should you perform?

A) The new database should be set to utilize the TRUSTWORTHY option, and then each user should be added to the MSDB database.
B) The MSDB database should be set to utilize the TRUSTWORTHY option, and then each user should be added to the MSDB database.
C) Each user should be added to the db_dtsltduser database role in the MSDB database.
D) Each user should be added to the public role in the MSDB database.

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

5. 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, software non-uniform memory access (soft-NUMA) should be configured.
C) To accomplish the goal, the Resource Governor should be configured.
D) To accomplish the goal, the Windows System Resource Manager should be configured.
