Microsoft Transition Your MCTS on SQL Server 2008 to MCSA: SQL Server 2012, Part 1 Sample Questions:

Question 1

You administer a Microsoft SQL Server 2012 server. One of the databases on the server supports a highly active OLTP application. Users report abnormally long wait times when they submit data into the application. You need to identify which queries are taking longer than 1 second to run over an extended period of time. What should you do?

A. Use SQL Profiler to trace all queries that are processing on the server. Filter queries that have a Duration value of more than 1,000.
B. Run the sp_who command from a query window.
C. Run the DBCC TRACEON 1222 command from a query window and review the SQL Server event log.
D. Use sp_configure to set a value for blocked process threshold. Create an extended event session.
E. Use the Job Activity monitor to review all processes that are actively running. Review the Job History to find out the duration of each step.

Question 2

You administer a Microsoft SQL Server 2012 database named ContosoDb. The database contains a table named Suppliers and a column named IsActive in the Purchases schema. You create a new user named ContosoUser in ContosoDb. ContosoUser has no permissions to the Suppliers table. You need to ensure that ContosoUser can delete rows that are not active from Suppliers. You also need to grant ContosoUser only the minimum required permissions. Which Transact-SQL statement should you use?

A. CREATE PROCEDURE Purchases.PurgeInactiveSuppliers AS DELETE FROM Purchases.Suppliers WHERE IsActive = 0
GO
GRANT EXECUTE ON Purchases.PurgeInactiveSuppliers TO ContosoUser
B. GRANT SELECT ON Purchases.Suppliers TO ContosoUser
C. CREATE PROCEDURE Purchases.PurgeInactiveSuppliers WITH EXECUTE AS USER = 'dbo' AS DELETE FROM Purchases.Suppliers WHERE IsActive = 0 GO GRANT EXECUTE ON Purchases.PurgelnactiveSuppliers TO ContosoUser
D. GRANT DELETE ON Purchases.Suppliers TO ContosoUser

Question 3

You have a Microsoft SQL Server 2012 database that contains tables named Customers and Orders. The tables are related by a column named CustomerID. You need to create a query that meets the following requirements:
Returns the CustomerName for all customers and the OrderDate for any orders that they have placed.
Results must include customers who have not placed any orders.
Which Transact-SQL query should you use?

A. SELECT CustomerName, OrderDate FROM Customers RIGHT OUTER JOIN Orders ON Customers.CustomerID = Orders.CustomerID
B. SELECT CustomerName, CrderDate FROM Customers JOIN Orders ON Customers.CustomerID = Orders.CustomerID
C. SELECT CustomerName, OrderDate FROM Customers LEFT OUTER JOIN Orders ON Customers.CustomerID = Orders.CustomerID
D. SELECT CustomerName, OrderDate FROM Customers CROSS JOIN Orders ON Customers.CustomerID = Orders.CustomerID

Question 4

You develop a Microsoft SQL Server 2012 database that has two tables named SavingAccounts and LoanAccounts. Both tables have a column named AccountNumber of the nvarchar data type. You use a third table named Transactions that has columns named TransactionId, AccountNumber, Amount, and TransactionDate. You need to ensure that when multiple records are inserted in the Transactions table, only the records that have a valid AccountNumber in the SavingAccounts or LoanAccounts are inserted. Which Transact-SQL statement should you use?

A. CREATE TRIGGER TrgValidateAccountNumber ON Transactions INSTEAD OF INSERT AS BEGIN
INSERT INTO Transactions SELECT TransactionID,AccountNumber,Amount,TransactionDate FROM inserted WHERE AccountNumber IN (SELECT AccountNumber FROM LoanAccounts UNION SELECT AccountNumber FROM SavingAccounts)) END
B. CREATE TRIGGER TrgValidateAccountNumber ON Transactions INSTEAD OF INSERT AS BEGIN
IF EXISTS (
SELECT AccountNumber FROM inserted EXCEPT
(SELECT AccountNumber FROM LoanAccounts
UNION SELECT AccountNumber FROM SavingAccounts))
BEGIN
ROLLBACK TRAN
END
END
C. CREATE TRIGGER TrgValidateAccountNumber ON Transactions FOR INSERT AS BEGIN
IF EXISTS (
SELECT AccountNumber FROM inserted EXCEPT
(SELECT AccountNumber FROM LoanAccounts
UNION SELECT AccountNumber FROM SavingAccounts))
BEGIN
ROLLBACK TRAN
END
END
D. CREATE TRIGGER TrgValidateAccountNumber ON Transactions FOR INSERT AS BEGIN
INSERT INTO Transactions SELECT TransactionID,AccountNumber,Amount,TransactionDate FROM inserted WHERE AccountNumber IN (SELECT AccountNumber FROM LoanAccounts UNION SELECT AccountNumber FROM SavingAccounts)) END

Question 5

You administer a Microsoft SQL Server 2012 instance that has several SQL Server Agent jobs configured.
When SQL Server Agent jobs fail, the error messages returned by the job steps are truncated. The
following error message is an example of the truncated error message:
"Executed as user CONTOSO\ServiceAccount. ...0.4035.00 for 64-bit Copyright (C) Microsoft Corp 1984-
2011. All rights reserved. Started 63513 PM Error 2012-06-23 183536.87 Code 0XC001000E Source
UserImport Description Code 0x00000000 Source Log Import Activity Descript... The package execution
fa... The step failed."
You need to ensure that all the details of the job step failures are retained for SQL Server Agent jobs.
What should you do?

A. Configure event forwarding.
B. Disable the Limit size of job history log feature.
C. Expand agent logging to include information from all events.
D. Configure output files.
