Answer: C
Explanation:
The first step to using media verification is selecting at least one tape drive in your library as a media verification drive. You should have at least two drives to ensure that there are no false positives due to a faulty tape drive. Tapes that fail verification are retried on the second drive, if available, before they are reported as faulty.
