Which of the following provides the GREATEST assurance that data can be recovered and restored in a timely manner in the event of data loss?
A . Backups of information are regularly tested.
B . Data backups are available onsite for recovery.
C . The recovery plan is executed during or after an event
D . full data backup is performed daily.

Answer: A

Explanation:

The feature that provides the GREATEST assurance that data can be recovered and restored in a timely manner in the event of data loss is that backups of information are regularly tested. This is because testing backups helps to ensure that they are valid, complete, and usable, and that they can be restored within the expected time frame and without errors or corruption. Testing backups also helps to identify and resolve any issues or problems with the backup process, media, or software. The other options are not features that provide the greatest assurance that data can be recovered and restored in a timely manner in the event of data loss, but rather different aspects or factors that affect the backup process, such as availability (B), execution C, or frequency (D) of backups.
