You administer a SQL Server 2008 infrastructure.
The instance contains a database required for the day-to-day business of your company. Users experience slow response time when they execute reports.
You plan to design a performance monitoring strategy that captures and stores the following data:
Executed Transact-SQL statements and query activity.
Blocking and deadlock information.
Counters for disk, CPU, and memory.
You need to implement the monitoring process by using the minimum amount of administrative effort.
What should you do?

• A. Use the data collector
• B. Use the client-side profiler trace.
• C. Use the dynamic management views.
• D. Use the System Monitor counter log trace.

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

You are a professional level SQL Sever 2008 Database Administrator.
A new database should be deployed, and the capacity requirements listed below should be satisfied.
There should be 275 GB for the database data file, while there should be 50 GB for the transaction log file. There are six 100-GB disk drives which are accessible for the database in the storage array. The six disks are attached to a redundant array of independent disks (RAID) controller, and the controller supports
RAID levels 0, 1, 5, and 10.
Since you are the technical support, you are required to maximize the write performance of the transaction
log. In addition, you should protect the database and transaction log files,
when a drive fails.
The storage system should be designed.
From the following four storage configuration, which one should you utilize?

• A. A single RAID 5 volume should be utilized.
• B. A RAID 1 volume and a RAID 5 volume should be utilized.
• C. A single RAID 10 volume should be utilized.
• D. A RAID 0 volume and a RAID 5 volume should be utilized.

You are a professional level SQL Sever 2008 Database Administrator.
A large database is hosted by the instance. The company utilizes the following backup strategy for the
database.
First, the performance of a full database backup is implemented at 02:00 hr every Monday.
Secondly, the performance of a differential backup is implemented at 23:00 hr every day.
Thirdly, the performance of a transaction log backup is implemented on an hourly basis.
A reboot is caused on the SQL Server 2008 server by a power failure at 09:15 hr, Thursday.
Fifteen minutes after the reboot of the server, it is reported that certain queries that access customer data
cannot be executed. You find that the customer data remains unvaried after the power failure.
When the DBCC CHECKDB command is executed on the database, the following error message is
received.
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 details.
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 allocation errors and 2 consistency errors in table
'tbl_Customer' (object ID 2814307832).
When the sp_help 'tbl_customer' stored procedure is executed, the following result set is received:
index_name index_description
PK clustered located on PRIMARY NCIX nonclustered located on PRIMARY
Since you are the technical support, you are required to make sure that the data should be accessible in the shortest time. And the impact on users should be cut to the least.
Which action will you perform to finish the task?

• A. To finish the task, the PK index should be dropped and recreated.
• B. To finish the task, the latest full database backup should be recovered. And then, the latest differential backup should be recovered. At last, all transaction log backups should be recovered from the latest differential backup.
• C. To finish the task, the NCIX index should be dropped and recreated.
• D. To finish the task, the latest full database backup should be recovered. And all transaction log backups should be recovered from the latest full database backup.

You administer a SQL Server 2008 infrastructure.
You plan to upgrade a Microsoft SQL Server 2005 instance to SQL Server 2008 by using an in-place
upgrade.
All user databases use the simple recovery model and have the PAGE_VERIFY option turned off.
You need to ensure that the database engine can identify I/O path errors and memory corruptions for the
data in tables.
Which two actions should you perform before the upgrade? (Each correct answer presents part of the
solution. Choose two.)

• A. Set the database recovery model to FULL.
• B. Rebuild the nonclustered indexes.
• C. Rebuild the clustered indexes and heaps.
• D. Set the PAGE_VERIFY database option to CHECKSUM.
• E. Execute the DBCC CHECKDB command by using the DATA_PURITY option.
• F. Set the PAGE_VERIFY database option to TORN_PAGE_DETECTION.
