database has the following backup strategies: A full database backup is performed once
a week. A differential backup is performed every day. A transaction log backup is
performed every hour. You plan to execute an end-of-year batch process that takes two
hours to run. The batch process will modify about five percent of data within the database.

batch operation can be rolled back in minimum possible time. What should you do prior to
starting the batch process?

A.
Perform a differential backup.

B.
Create a database snapshot.

C.
Create a marked transaction. Perform a transaction log backup.
