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.)
You are a professional level SQL Sever 2008 Database Administrator in an international corporation named Wiikigo.
A 32-bit version is utilized by the instance on a Windows Server 2008 64-bit server. You activate the awe enabled option. A predictable increase in query activity will be experienced by the instance. You are required to figure out the most proper and beneficial time to have the databases migrated to a 64-bit SQL Server 2008 server on the same hardware.
A data collector type that proper information is provided should be identified.
What kind of collector should you utilize?
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.)
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?
You are the database administrator for a SQL Server that hosts an application defined as follows:
The database consists of 4 data files and one log file.
The physical server has 16 CPUs and 64 GB of memory.
Hardware non-uniform memory access (NUMA) is not available on this server platform.
Users of the application report that it is responding slowly. You use SQL Server Profiler to find out that the I/
O
performance issue is related to the lazywriter process.
You need to improve the performance of the application by reducing the I/O performance issue.
