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 that contains a financial database hosted on a storage area network (SAN). The financial database has the following characteristics:
A data file of 2 terabytes is located on a dedicated LUN (drive D).
A transaction log of 10 GB is located on a dedicated LUN (drive E).
Drive D has 1 terabyte of free disk space.
Drive E has 5 GB of free disk space.
The database is continually modified by users during business hours from Monday through Friday between
09:00
hours and 17:00 hours. Five percent of the existing data is modified each day. The Finance department loads large CSV files into a number of tables each business day at 11:15 hours and 15:15 hours by using the BCP or BULK INSERT commands. Each data load adds 3 GB of data to the database. These data load operations must occur in the minimum amount of time. A full database backup is performed every Sunday at 10:00 hours. Backup operations will be performed every two hours (11:00, 13:00, 15:00, and 17:00) during business hours. On Wednesday at 10:00 hours, the development team requests you to refresh the database on a development server by using the most recent version. You need to perform a full database backup that will be restored on the development server. Which backup option should you use?

A) COPY_ONLY
B) Differential
C) Transaction log
D) NO_CHECKSUM
E) SKIP
F) FULL
G) 8ULK_LOGGED
H) STANDBY
I) NORECOVERY
J) SIMPLE
K) DBO ONLY
L) CONTINUE AFTER ERROR
M) RESTART
N) CHECKSUM

2. 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.)
Build List and Reorder:

3. You administer a Microsoft SQL Server 2012 instance. You need to configure a new database to support FILETABLES. What should you do? Choose all that apply.

A) Enable Contained Databases on the Server Instance.
B) Disable FILESTREAM on the Database.
C) Create a non-empty FILESTREAM file group.
D) Enable FILESTREAM on the Server Instance.
E) Set the FILESTREAM directory name on the Database.
F) Configure the Database for Partial Containment.

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) Set the Remote Connection Timeout on the Publisher to 0.
B) Set the Merge agent on the problem subscribers to use the slow link agent profile.
C) Create a snapshot publication, and reconfigure the problem subscribers to use the snapshot publication.
D) Change the Merge agent on the problem subscribers to run continuously.

5. You are developing a database application by using Microsoft SQL Server 2012. An application that uses a database begins to run slowly. Your investigation shows the root cause is a query against a read-only table that has a clustered index. The query returns the following six columns: * One column in its WHERE clause contained in a non-clustered index * Four additional columns * One COUNT (*) column based on a grouping of the four additional columns.
You need to optimize the statement. What should you do?

A) Add a FORCESCAN hint to the Attach query.
B) Add a HASH hint to the query.
C) Include a SET TRANSACTION ISOLATION LEVEL REPEATABLE READ statement before you run the query.
D) Add an INCLUDE clause to the index.
E) Cover the unique clustered index with a columnstore index.
F) Add a columnstore index to cover the query.
G) Include a SET TRANSACTION ISOLATION LEVEL SERIALIZABLE statement before you run the query.
H) Add a FORCESEEK hint to the query.
I) Include a SET STATISTICS PROFILE ON statement before you run the query.
J) Enable the optimize for ad hoc workloads option.
K) Add a LOOP hint to the query.
L) Include a SET STATISTICS SHOWPLAN_XML ON statement before you run the query.
M) Include a SET TRANSACTION ISOLATION LEVEL SNAPSHOT statement before you run the query.
N) Include a SET FORCEPLAN ON statement before you run the query.
