Microsoft Transition Your MCTS on SQL Server 2008 to MCSA: SQL Server 2012, Part 1 Sample Questions:

1. You use Microsoft SQL Server 2012 database to develop a shopping cart application. You need to rotate the unique values of the ProductName field of a table-valued expression into multiple columns in the output. Which Transact-SQL operator should you use?

A) CROSS JOIN
B) CROSS APPLY
C) PIVOT
D) UNPIVOT

2. You use a Microsoft SQL Server 2012 database that contains two tables named SalesOrderHeader and SalesOrderDetail. The indexes on the tables are as shown in the exhibit. (Click the Exhibit button.)

You write the following Transact-SQL query:

You discover that the performance of the query is slow. Analysis of the query plan shows table scans where the estimated rows do not match the actual rows for SalesOrderHeader by using an unexpected index on SalesOrderDetail. You need to improve the performance of the query. What should you do?

A) Use a FORCESCAN hint in the query.
B) Use a FORCESEEK hint in the query.
C) Add a clustered index on SalesOrderId in SalesOrderHeader.
D) Update statistics on SalesOrderId on both tables.

3. You administer all the deployments of Microsoft SQL Server 2012 in your company. You need to ensure that an OLTP database that includes up-to-the-minute reporting requirements can be off-loaded from the primary database to another server. You also need to be able to add indexes to the secondary database. Which configuration should you use?

A) Two servers configured in different data centers SQL Server Availability Group configured in Synchronous-Commit Availability Mode One server configured as an Active Secondary
B) Two servers configured in the same data center A primary server configured to perform log-shipping every 10 minutes * A backup server configured as a warm standby
C) Two servers configured in the same data center SQL Server Availability Group configured in Asynchronous-Commit Availability Mode One server configured as an Active Secondary
D) Two servers configured in different data centers SQL Server Availability Group configured in Asynchronous-Commit Availability Mode
E) Two servers configured on the same subnet SQL Server Availability Group configured in Synchronous-Commit Availability Mode
F) SQL Server that includes an application database configured to perform snapshot replication
G) SQL Server that includes an application database configured to perform transactional replication
H) Two servers configured in a Windows Failover Cluster in the same data center SQL Server configured as a clustered instance

4. You administer several Microsoft SQL Server 2012 database servers. Merge replication has been configured for an application that is distributed across offices throughout a wide area network (WAN). Many of the tables involved in replication use the XML and varchar(max) data types. Occasionally, merge replication fails due to timeout errors. You need to reduce the occurrence of these timeout errors. What should you do?

A) Create a snapshot publication, and reconfigure the problem subscribers to use the snapshot publication.
B) Change the Merge agent on the problem subscribers to run continuously.
C) Set the Remote Connection Timeout on the Publisher to 0.
D) Set the Merge agent on the problem subscribers to use the slow link agent profile.

5. You administer a Microsoft SQL Server instance. You use a two-node SQL Server failover cluster. Node B is primary, and Node A is secondary. You need to install a security patch on both nodes. You need to ensure that the following requirements are met:
Both nodes receive the update.
Downtime is minimized.
No data is lost.
Which three actions should you perform in sequence? (To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.)
