CompTIA CASP+ (CAS-004) — Question 218

A significant weather event caused all systems to fail over to the disaster recovery site successfully. However, successful data replication has not occurred in the last six months, which has resulted in the service being unavailable. Which of the following would BEST prevent this scenario form happening again?

Answer options

• A. Performing routine tabletop exercises
• B. Implementing scheduled, full interruption tests
• C. Backing up system log reviews
• D. Performing department disaster recovery walk-throughs

Correct answer: B

Explanation

Implementing scheduled, full interruption tests (B) ensures that the entire system can be effectively switched to the disaster recovery site, including data replication processes. The other options, while useful, do not directly address the need for tested and reliable data replication during actual disaster scenarios.
