You use Microsoft SQL Server 2012 to develop a database application. You need to create an object that meets the following requirements:
Takes an input variable
Returns a table of values
Cannot be referenced within a view
Which object should you use?

• A.Stored procedure
• B.User-defined data type
• C.Scalar-valued function
• D.Inline function

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 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
• D.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

You develop a database for a travel application. You need to design tables and other database objects. You create the Airline_Schedules table. You need to store the departure and arrival dates and times of flights along with time zone information. What should you do?

• A.Add a LOOP hint to the query.
• B.Include a SET FORCEPLAN ON statement before you run the query.
• C.Add a FORCESCAN hint to the Attach query.
• D.Add a columnstore index to cover the query.
• E.Add a FORCESEEK hint to the query.
• F.Add a HASH hint to the query.
• G.Include a SET STATISTICS PROFILE ON statement before you run the query.
• H.Cover the unique clustered index with a columnstore index.
• I.Add an INCLUDE clause to the index.
• J.Enable the Optimize for ad hoc workloads option.

You administer two Microsoft SQL Server 2012 servers named ServerA and ServerB. You use a database named AdventureWorks. You need to prepare the AdventureWorks database for database mirroring.
