Certified in Risk and Information Systems Control (CRISC) — Question 291

Which of the following is the MOST appropriate key risk indicator (KRI) for backup media that is recycled monthly?

Answer options

• A. Time required for backup restoration testing.
• B. Change in size of data backed up.
• C. Successful completion of backup operations.
• D. Percentage of failed restore tests.

Correct answer: D

Explanation

The correct answer is D because tracking the percentage of failed restore tests directly indicates the reliability of the backup media. If restore tests fail, it suggests potential issues with the media, which is critical for ensuring data recovery. The other options, while relevant to backup processes, do not specifically address the effectiveness and reliability of the backup media itself.
