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

1. You are migrating a database named Orders to a new server that runs Microsoft SQL Server 2012. You
attempt to add the [Corpnet\User1] login to the database. However, you receive the following error
message:
"User already exists in current database."
You need to configure the [Corpnet\User1] login to be able to access the Orders database and retain the
original permissions. You need to achieve this goal by using the minimum required permissions.
Which Transact-SQL statement should you use?

A) ALTER SERVER ROLE [sysadmin] ADD MEMBER [Corpnet\User1];
B) ALTER ROLE [db_owner] ADD MEMBER [Corpnet\User1];
C) DROP USER [User1]; CREATE USER [Corpnet\User1] FOR LOGIN [Corpnet\User1]; ALTER ROLE [db_owner] ADD MEMBER [Corpnet\User1];
D) ALTER USER [Corpnet\User1] WITH LOGIN [Corpnet\User1];

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

3. 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. You need to ensure that the backup size is as small as possible. Which backup should you perform every two hours?

A) DBO.ONLY
B) RESTART
C) CONTINUE_AFTER_ERROR
D) SIMPLE
E) CHECKSUM
F) STANDBY
G) BULK_LOGGED
H) Differential
I) SKIP
J) COPY_ONLY
K) FULL
L) NO_CHECKSUM
M) NORECOVERY
N) Transaction log

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

5. You are developing a database application by using Microsoft SQL Server 2012. An application that uses a database begins to run slowly. You discover that during reads, the transaction experiences blocking from concurrent updates. You need to ensure that throughout the transaction the data maintains the original version. What should you do?

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