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

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

2. You are a professional level SQL Sever 2008 Database Administrator.
A mission-critical database is shared by the five sites.
According to the business requirements, the users at each site should be enabled to access and change data on all sites with minimal latency. In addition, data loss should be minimized if a server fails. A high-availability solution should be designed, and the business requirements should be satisfied.
Which action should be included in your solution?

A) Asynchronous database mirroring without a witness server should be included.
B) Peer-to-Peer replication should be included.
C) Failover clustering should be included.
D) Log shipping to servers at two of the sites to offer read-only replications of data should be included.

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

4. You are a professional level SQL Sever 2008 Database Administrator.
The security requirements should be designed for a new database application, and the application will be deployed to the instance. A table is consisted by the new database, and the table is created by utilizing the following code segment:
TABLE EmpBonusPlan
Since you are the technical support, you should utilize the maximum secure method to protect the BonusPlan column from the access of unauthorized users.
Which action will you perform to finish the task?

A) To finish the task, the Trustworthy option for the database should be utilized.
B) To finish the task, the NTFS file system security should be utilized and the access of the database files should be limited to the SQL Server 2008 Service account.
C) To finish the task, Transparent data encryption should be utilized.
D) To finish the task, the Advanced Encryption Standard encryption should be utilized on all columns in the database.

5. 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 forced service role switching.
C) Configure automatic failover role switching.
D) Configure manual failover role switching.
