You develop a database for a travel application. You need to design tables and other database objects. You need to store media files in several tables. Each media file is less than 1 MB in size. The media files will require fast access and will be retrieved frequently. What should you do?

• A. Use the DATETIME data type.
• B. Use the DATE data type.
• C. Use an appropriate collation.
• D. Use the DATETIME2 data type.
• E. Use the TODATETIMEOFFSET function.
• F. Use the CAST function.
• G. Use the DATETIMEOFFSET data type.
• H. Use the FORMAT function.
• I. Use a user-defined table type.
• J. Use the VARBINARY data type.

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 Merge agent on the problem subscribers to use the slow link agent profile.
• D. Set the Remote Connection Timeout on the Publisher to 0.

You administer a Microsoft SQL Server 2012 failover cluster that contains two nodes named Node A and Node B.
A single instance of SQL Server is installed on the cluster. An additional node named Node C has been added to the existing cluster. You need to ensure that the SQL Server instance can use all nodes of the cluster. What should you do?

• A. Run the Add Node to SQL Server Failover Cluster Wizard on Node C.
• B. Use Node A to install SQL Server on Node C.
• C. Run the New SQL Server stand-alone installation Wizard on Node C.
• D. Use Node B to install SQL Server on Node

You develop a Microsoft SQL Server 2012 database that contains tables named Employee and Person. The tables have the following definitions:

You create a view named VwEmployee as shown in the following Transact-SQL statement.

Users are able to use single INSERT statements or INSERT...SELECT statements into this view. You need to ensure that users are able to use a single statement to insert records into both Employee and Person tables by using the VwEmployee view. Which Transact-SQL statement should you use?

• A. CREATE TRIGGER TrgVwEmployee ON VwEmployee INSTEAD OF INSERT AS BEGIN INSERT INTO Person(Id, FirstName, LastName) SELECT Id, FirstName, LastName, FROM inserted
  INSERT INTO Employee(PersonId, EmployeeNumber)
  SELECT Id, EmployeeNumber FROM inserted
  END
• B. CREATE TRIGGER TrgVwEmployee ON VwEmployee INSTEAD OF INSERT AS BEGIN INSERT INTO Person(Id, FirstName, LastName) SELECT Id, FirstName, LastName FROM VwEmployee
  INSERT INTO Employee(PersonID, EmployeeNumber)
  SELECT Id, EmployeeNumber FROM VwEmployee
  End
• C. CREATE TRIGGER TrgVwEmployee ON VwEmployee FOR INSERT AS BEGIN INSERT INTO Person(Id, FirstName, LastName) SELECT Id, FirstName, LastName, FROM inserted
  INSERT INTO Employee(PersonId, EmployeeNumber)
  SELECT Id, EmployeeNumber FROM inserted
  END
• D. CREATE TRIGGER TrgVwEmployee ON VwEmployee INSTEAD OF INSERT AS BEGIN
  DECLARE @ID INT, @FirstName NVARCHAR(25), @LastName NVARCHAR(25), @PersonID INT, @EmployeeNumber NVARCHAR(15)
  SELECT @ID = ID, @FirstName = FirstName, @LastName = LastName,
  @EmployeeNumber = EmployeeNumber
  FROM inserted
  INSERT INTO Person(Id, FirstName, LastName)
  VALUES(@ID, @FirstName, @LastName)
  INSERT INTO Employee(PersonID, EmployeeNumber)
  VALUES(@PersonID, @EmployeeNumber
  End

You are developing a database application by using Microsoft SQL Server 2012. You have a query that runs slower than expected. You need to capture execution plans that will include detailed information on missing indexes recommended by the query optimizer. What should you do?

• A. Include a SET TRANSACTION ISOLATION LEVEL SERIALIZABLE statement before you run the query.
• B. Add a HASH hint to the query.
• C. Cover the unique clustered index with a columnstore index.
• D. Include a SET TRANSACTION ISOLATION LEVEL SNAPSHOT statement before you run the query.
• E. Add a columnstore index to cover the query.
• F. Add a FORCESEEK hint to the query.
• G. Add a LOOP hint to the query.
• H. Add an INCLUDE clause to the index.
• I. Include a SET STATISTICS PROFILE ON statement before you run the query.
• J. Enable the optimize for ad hoc workloads option.
• K. Include a SET TRANSACTION ISOLATION LEVEL REPEATABLE READ statement before you run the query.
• L. Include a SET FORCEPLAN ON statement before you run the query.
• M. Add a FORCESCAN hint to the Attach query.
• N. Include a SET STATISTICS SHOWPLAN_XML ON statement before you run the query.
