Microsoft 70-457 Exam Syllabus Topics:

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

1. You administer a Microsoft SQL Server 2012 instance. The instance contains a database that supports a retail sales application. The application generates hundreds of transactions per second and is online 24 hours per day and 7 days per week. You plan to define a backup strategy for the database. You need to ensure that the following requirements are met:
No more than 5 minutes worth of transactions are lost.
Data can be recovered by using the minimum amount of administrative effort.
What should you do? Choose all that apply.

A) Create a DIFFERENTIAL database backup every 24 hours.
B) Configure the database to use the SIMPLE recovery model.
C) Create a LOG backup every 5 minutes.
D) Create a FULL database backup every 24 hours.
E) Create a DIFFERENTIAL database backup every 4 hours.
F) Configure the database to use the FULL recovery model.

2. 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 FILE = 'd:\TDE_Certificate.cer';
B) ALTER DATABASE Master SET ENCRYPTION OFF;
C) CREATE CERTIFICATE TDE_Certificate WITH SUBJECT = 'TDE Certificate'; USE Orders; CREATE DATABASE ENCRYPTION KEY
WITH ALGORITHM = AES_256
ENCRYPTION BY SERVER CERTIFICATE TDE_Certificate;
D) CREATE CERTIFICATE TDE_Certificate FROM FILE = 'd:\TDE_Certificate.cer' WITH PRIVATE KEY (FILE = 'D:\TDE_Certificate.key', DECRYPTION BY PASSWORD = 'MyPassword1!');

3. You use Microsoft SQL Server 2012 to create a stored procedure as shown in the following code segment. (Line numbers are included for reference only.)

The procedure can be called within other transactions. You need to ensure that when the DELETE statement from the HumanResourcesJobCandidate table succeeds, the modification is retained even if the insert into the Audit.Log table fails. Which code segment should you add to line 14?

A) IF @@TRANCOUNT = 1
B) IF (XACT_STATE ( ) ) = 1
C) IF (XACT_STATE ( ) ) = 0
D) IF @@TRANCOUNT = 0

4. 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) Run the sp_who command from a query window.
B) Use sp_configure to set a value for blocked process threshold. Create an extended event session.
C) 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.
D) Run the DBCC TRACEON 1222 command from a query window and review the SQL Server event log.
E) 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.

5. You administer a Microsoft SQL Server 2012 database. All database traffic to the SQL Server must be encrypted by using secure socket layer (SSL) certificates or the connection must be refused. Network
administrators have deployed server certificates to the Windows store of all Windows servers on the
network from a trusted Certificate Authority. This is the only Certificate Authority allowed to distribute
certificates on the network.
You enable the Force Encryption flag for the MSSQLServer protocols, but client computers are unable to
connect. They receive the following error message:
"A connection was successfully established with the server, but then an error occurred during the pre-login
handshake, (provider: SSL Provider, error: 0 - The certificate chain was issued by an authority that is not
trusted.) (Microsoft SQL Server)"
You notice the following entry in the SQL Server log:
"A self-generated certificate was successfully loaded for encryption."
You need to configure SQL Server to encrypt all client traffic across the network. You also need to ensure
that client computers are able to connect to the server by using a trusted certificate. Which three actions
should you perform in sequence? (To answer, move the appropriate actions from the list of actions to the
answer area and arrange them in the correct order.)
