Microsoft PRO:MS SQL Serv 08,Design,Optimize, and Maintain DB Admin Solu Sample Questions:
1. You administer a SQL Server 2008 infrastructure.
A financial application uses several instances across multiple servers. The majority of queries require distributed transactions across all servers.
The application administrator reports that the application experiences excessive deadlocks.
You need to design a data collector type that provides the appropriate information for remote servers.
What collector should you use?
A) Performance Counters collector
B) Query Activity collector
C) T-SQL Query collector
D) A custom Query collector that uses WMI
2. 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) Certificate-based encryption
C) Transparent data encryption
D) Symmetric key encryption
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) Review system monitor counters on a regular basis.
B) Clear the system log and the application log every hour.
C) Baseline the system before you deploy production databases.
D) Create a maintenance plan that rebuilds indexes every week.
E) Backup all databases every day.
4. You are a professional level SQL Sever 2008 Database Administrator.
They are respectively named Ins01, Ins02, Ins03 and Ins04. A single database application is hosted by each instance. All four instances should be removed to a new SQL Server failover cluster. You can see the configuration of the four instances from the table listed below:
All the four instances are sufficiently optimized, and there are no spare CPU cycles or extra memory in
the instances.
All four databases will be hosted by the new cluster on a single virtual cluster IP address.
Since you are the technical support, you are required to set the new cluster to handle the workload of all the database applications with the least amount of hardware resources.
From the four cluster configuration, which one should be utilized?
A) Four-node active/active/active/passive cluster should be utilized and a minimum of 18 processors and a 50-GB memory are contained by each node.
B) Two-node active/passive cluster should be utilized and a minimum of 18 processors and a 50-GB memory are contained by each node.
C) Two-node active/active cluster should be utilized and a minimum of 9 processors and a 25-GB memory are contained by each node.
D) Four-node active/active/active/active cluster should be utilized and a minimum of 9 processors and a 25-GB memory are contained by each node.
5. You administer a SQL Server 2008 instance that hosts a large database.
The following backup strategy is used for the database:
A full database backup is performed at 02:00 hr every Monday.
A differential backup is performed at 23:00 hr every day.
A transaction log backup is performed on an hourly basis.
A power failure on Thursday causes the SQL Server 2008 server to restart at 09:15 hr.
Fifteen minutes after the server restarts, the users report that they are unable to execute certain queries
that access
customer data. You discover that the customer data is unmodified after the power failure.
When you execute the DBCC CHECKDB command on the database, you receive the following error
message:
Object ID 2814307832, index ID 2, partition ID 83127819437122157, alloc unit ID 82134587923221126
(type In-row data): Page (3421:169) could not be processed. See other errors for d etails.
Table error: Object ID 2814307832, index ID 2, partition ID 83127819437122157, alloc unit ID
82134587923221126 (type In-row data), page (3421:169). Test (IS_OFF (BUF_IOERR, pBUF- > bstat))
failed. Values are 16928422 and -8.
CHECKDB found 0 allocatio n errors and 2 consistency errors in table 'tbl_Customer' (object ID
2814307832).
When you execute the sp_help 'tbl_customer' stored procedure you receive the following result set:
index_name index_description
PK clustered located on PRIMARY
NCIX nonclustered located on PRIMARY
You need to ensure that the data is available as quickly as possible with minimal effect on users.
What should you do?
A) Drop and recreate the NCIX index.
B) Restore the latest full database backup. Restore the latest differential backup. Restore all transaction log backups from the latest differential backup.
C) Restore the latest full database backup. Restore all transaction log backups from the latest full database backup.
D) Drop and recreate the PK index.
