Q71. You develop a Microsoft SQL Server 2012 database that contains tables named Employee and Person. The tables have the following definitions:
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 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
B. 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

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

Q72. You administer two Microsoft SQL Server 2012 servers named ProdSrv1 and ProdSrv2. ProdSrv1 is configured as a Distributor. Both servers are configured to use the Windows NT Service virtual accounts for all SQL Services.
You are configuring snapshot replication from ProdSrv1 to ProdSrv2 by using ProdSrv2 as
a pull subscriber.
The distribution agent on ProdSrv2 regularly fails, displaying the following error message:
