Which of the following procedures would an entity most
likely include in its computer disaster recovery plan?

(b) The requirement is to identify the most likely procedure
to be included in a computer disaster recovery plan. Answer
(b) is correct because duplicate copies of critical files will
allow an entity to reconstruct the data whose original files have
been lost or damaged. Answer (a) is incorrect because an auxiliary
power supply will provide uninterrupted electricity to avoid
the need for a recovery since it may reduce the likelihood of such
a disaster. Answer (c) is incorrect because simply maintaining
passwords will not allow the entity to reconstruct data after a
disaster has occurred. Answer (d) is incorrect because while
cryptography will enhance the security of files from unintended
uses, it is not a primary method to recover from a computer disaster.
