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.

You need to ensure that the table has no duplicate CustomerID within a SourceID. You also need to ensure that the data in the table is in the order of SourceID and
then CustomerID. Which Transact- SQL statement should you use?

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.
Your solution must provide scale-out of read operations by distributing the reads from clients across two SQL Server 2012 nodes. The data in both SQL Server
nodes needs to be indexed.
What should you include in your solution?

You administer a Microsoft SQL Server 2012 database.
You have a SQL Server Agent job instance that runs using the service account. You have a job step within the job that requires elevated privileges.
You need to ensure that the job step can run using a different user account.
What should you use?

You administer a Microsoft SQL Server 2012 database instance. You create a new user named UserA.
You need to ensure that UserA is able to create SQL Server Agent jobs and execute SQL Server agent jobs owned by UserA
To which role should you add UserA?

You administer a Microsoft SQL Server 2012 instance named SQL2012. You are in the process of migrating a database from a SQL Server 2008 instance named
SQL2008 to the SQL2012 instance.
You have upgraded a database from the SQL2008 instance by using the side-by-side migration technique.
You need to migrate the SQL Server logins from the SQL2008 instance to the SQL2012 instance.
What should you do?

You plan to install a Microsoft SQL Server 2012 instance.
The instance will support a database that has the following requirements:
Store Excel workbooks on the file system.
Access the workbooks through Transact-SQL.
Include the workbooks in database backups.
During installation, you need to ensure that the requirements will be met.
Which feature should you use?

You plan to install Microsoft SQL Server 2012 for a web hosting company.
The company plans to host multiple web sites, each supported by a SQL Server database.
You need to select an edition of SQL Server that features backup compression of databases, basic data integration features, and low total cost of ownership.
Which edition should you choose?

You administer a Microsoft SQL Server 2012 database named Contoso on a server named Server01.

You need to collect data for a long period of time to troubleshoot wait statistics when querying Contoso. You also need to ensure minimum impact to the server.
What should you create?

You administer a Microsoft SQL Server 2012 database named Contoso on a server named Server01.
You need to track all SELECT statements issued in the Contoso database only by users in a role named Sales.
What should you create?

You administer a Microsoft SQL Server 2012 environment. One of the SQL Server 2012 instances contains a database named Sales.
