Which of the following is the MOST important to ensure a successful recovery?
A.
Backup media is stored offsite
B.
Recovery location is secure and accessible
C.
More than one hot site is available
D.
Network alternate links are regularly tested
Explanation:
Unless backup media are available, all other preparations become meaningless. Recovery site location and security are important, but would not prevent recovery in a disaster situation. Having a secondary hot site is also important, but not as important as having backup media available. Similarly, alternate data communication lines should be tested regularly and successfully but, again, this is not as critical.
