Which of the following best describes a full backup?
A.
All datafiles of a database
B.
All datafiles, archive logs, and control files
C.

Explanation:

“Full backup: Makes a copy of each data block that contains data and that is within the files being backed up.”
“A full backup contains all used data file blocks.”
“A full backup is different from a whole database backup.”
