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 S 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.CHECKSUM
• B.DBO_ONLY
• C.FULL

• E.BULK_LOGGED
• F.COPY_ONLY
• G.Transaction log
• H.NO_CHECKSUM
