Q22. 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?

B. FULL 

C. NO_CHECKSUM 

D. CHECKSUM 

E. Differential 

F. 8ULK_LOGGED
