Which of the following would BEST support 24/7 availability?
A.
Daily backup
B.
Offsite storage
C.
Mirroring
D.
Periodic testing
Explanation:
Mirroring of critical elements is a too! that facilitates immediate recoverability. Daily backup implies that it is
reasonable for restoration to take place within a number of hours but not immediately. Offsite storage and
periodic testing of systems do not of themselves support continuous availability.
