QUESTION 163

You have been hired as a Database Consultant by ABC.com to design a SQL Server 2012 database solution. You are tasked with designing a scale-out and high-availability SQL Server 2012 Online Transaction Processing (OLTP) database solution that will maintain copies of data across two server instances.

You should include two servers configured in an Active-Active SQL Server 2012 Cluster

B.

You should include a primary SQL Server 2012 database that uses transactional replication to replicate

data to a secondary database.

C.

You should include two servers configured in an Active-Passive SQL Server 2012 Cluster.

D.

You should include two servers in an Asynchronous-Commit Availability Mode Availability Group.

E.

You should include two servers in a Synchronous-Commit Availability Mode Availability Group

 

Correct Answer: B

 

 

QUESTION 164

You are a database developer of a Microsoft SQL Server 2012 database. You are designing a table that will store Customer data from different sources. The table will include a column that contains the CustomerID from the source system and a column that contains the SourceID. A sample of this data is as shown in the following table.

Reference a user-defined function within the computed column.

B.

Create a BEFORE trigger that maintains the state of the computed column.

C.

Add a default constraint to the computed column that implements hard-coded values.

QUESTION 169

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.)

 

clip_image015

 

You write the following Transact-SQL query:

 

clip_image017

 

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?

 

< tr style="mso-yfti-irow: 3; mso-yfti-lastrow: yes">

A.

Use a FORCESCAN hint in the query.

B.

Add a clustered index on SalesOrderId in SalesOrderHeader.

C.

Use a FORCESEEK hint in the query.

D.

Update statistics on SalesOrderId on both tables.
