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

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

2. You administer a Microsoft SQL Server 2012 database. The database contains a table named Employee. Part of the Employee table is shown in the exhibit. (Click the Exhibit button.)


Confidential information about the employees is stored in a separate table named EmployeeData. One record exists within EmployeeData for each record in the Employee table. You need to assign the appropriate constraints and table properties to ensure data integrity and visibility. On which column in the Employee table should you a create a unique constraint?

A) LastName
B) EmployeeNum
C) JobTitle
D) DateHired
E) FirstName
F) MiddleName
G) ReportsToID
H) DepartmentID
I) EmployeelD

3. You administer a Microsoft SQL Server 2012 database. You configure Transparent Data Encryption (TDE) on the Orders database by using the following statements:
CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'MyPassword1!';
CREATE CERTIFICATE TDE_Certificate WITH SUBJECT = 'TDE Certificate';
BACKUP CERTIFICATE TDE_Certificate TO FILE = 'd:\TDE_Certificate.cer'
WITH PRIVATE KEY (FILE = 'd:\TDE_Certificate.key', ENCRYPTION BY PASSWORD =
'MyPassword1!');
CREATE DATABASE ENCRYPTION KEY
WITH ALGORITHM = AES_256
ENCRYPTION BY SERVER CERTIFICATE TDE_Certificate;
ALTER DATABASE Orders SET ENCRYPTION ON;
You attempt to restore the Orders database and the restore fails. You copy the encryption file to the original location. A hardware failure occurs and so a new server must be installed and configured. After installing SQL Server to the new server, you restore the Orders database and copy the encryption files to their original location. However, you are unable to access the database. You need to be able to restore the database. Which Transact-SQL statement should you use before attempting the restore?

A) CREATE CERTIFICATE TDE_Certificate FROM EXECUTABLE FILE = 'd:\TDE_Certificate.cer'
B) CREATE CERTIFICATE TDE_Certificate FROM FILE = 'd:\TDE_Certificate.cer' WITH PRIVATE KEY (FILE = 'd:\TDE_Certificate.key', DECRYPTION BY PASSWORD 'MyPassword1!');
C) CREATE ASSEMBLY TDE_Assembly FROM 'd:\TDE_Certificate.cer' WITH PERMISSION_SET = SAFE;
GO
CREATE CERTIFICATE TDE_Certificate
FROM ASSEMBLY TDE_Assembly;
D) DECLARE @startdate date SET @startdate = GETDATE() CREATE CERTIFICATE TDE_Certificate FROM FILE = 'd:\TDE_Certificate.cer' WITH START_DATE = @startdate;

4. 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) Change the Merge agent on the problem subscribers to run continuously.
B) Create a snapshot publication, and reconfigure the problem subscribers to use the snapshot publication.
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.

5. You administer a Microsoft SQL Server 2012 database named ContosoDb. Tables are defined as shown in the exhibit. (Click the Exhibit button.)

You need to display rows from the Orders table for the Customers row having the CustomerId value set to 1 in the following XML format.
<CUSTOMERS Name="Customer A" Country="Australia"> <ORDERS OrderID="1" OrderDate="2001-01-01" Amount="3400.00" /> <ORDERS OrderID="2" OrderDate="2002-01-01" Amount="4300.00" />
</CUSTOMERS>
Which Transact-SQL query should you use?

A) SELECT OrderId, OrderDate, Amount, Name, Country FROM Orders INNER JOIN Customers ON Orders.CustomerId = Customers. CustomerId WHERE Customers.CustomerId = 1 FOR XML RAW, ELEMENTS
B) SELECT OrderId, OrderDate, Amount, Name, Country FROM Orders INNER JOIN Customers ON Orders.CustomerId = Customers. CustomerId WHERE Customers.CustomerId = 1 FOR XML AUTO
C) SELECT Name AS 'Customers/Name', Country AS 'Customers/Country', OrderId, OrderDate, Amount FROM Orders INNER JOIN Customers ON Orders.CustomerId = Customers. CustomerId WHERE Customers.CustomerId = 1 FOR XML PATH ('Customers')
D) SELECT Name, Country, OrderId, OrderDate, Amount FROM Orders INNER JOIN Customers ON Orders.CustomerId = Customers. CustomerId WHERE Customers.CustomerId = 1 FOR XML AUTO, ELEMENTS
E) SELECT Name AS '@Name', Country AS '@Country', OrderId, OrderDate, Amount FROM Orders INNER JOIN Customers ON Orders.CustomerId = Customers. CustomerId WHERE Customers.CustomerId = 1 FOR XML PATH ('Customers')
F) SELECT OrderId, OrderDate, Amount, Name, Country FROM Orders INNER JOIN Customers ON Orders.CustomerId = Customers. CustomerId WHERE Customers.CustomerId = 1 FOR XML AUTO, ELEMENTS
