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.
NORECOVERY

B.
FULL

C.
NO_CHECKSUM

D.
CHECKSUM

E.
Differential

F.
BULK_LOGGED

G.
STANDBY

H.
RESTART

I.
SKIP

J.
Transaction log
K.
DBO ONLY
L.
COPY_ONLY
M.
SIMPLE
N.
CONTINUE AFTER ERROR

Explanation:
Minimally, you must have created at least one full backup before you can create any log backups. After that, the
transaction log can be backed up at any time unless the log is already being backed up.
