Certified Information Security Manager (CISM) — Question 826

The contribution of recovery point objective (RPO) to disaster recovery is to:

Answer options

• A. eliminate single points of failure.
• B. reduce mean time between failures (MTBF).
• C. define backup strategy.
• D. minimize outage periods.

Correct answer: C

Explanation

The correct answer is C because the recovery point objective (RPO) directly informs how often data backups should occur, ensuring minimal data loss in case of a disaster. Options A and B are related to system reliability but do not pertain to RPO, while D focuses on outage duration rather than backup strategy.
