Exam Name: PRO: Designing, Optimizing and Maintaining a Database Administrative Solution Using Microsoft SQL Server 2008

QUESTION 1

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?
