A failure recovery drill should simulate recovery procedures and what else?

• A. Rerouting communications to maintain operations.
• B. Extended maintenance downtime.
• C. Additional redundant hardware procurement.
• D. Recovery procedures and rerouting.

Answer: (D)

In a failure recovery drill, you’re testing both how you restore normal operations and how you keep services running while that restoration happens. The best choice combines recovery procedures with rerouting, because real outages require not only fixing the systems but also redirecting communications or traffic to alternate paths so users aren’t left waiting. This dual focus verifies that you can recover services quickly while maintaining continuity.

The other options miss the full scope: extending maintenance downtime doesn’t simulate actual recovery, since it delays restoration; procuring additional redundant hardware is about future capacity rather than practicing a live drill; and testing rerouting alone doesn’t confirm that the recovery steps themselves can be carried out effectively within the needed timelines.
