Certified Information Security Manager (CISM) — Question 477

Which is the BEST method to evaluate the effectiveness of an alternate processing site when continuous uptime is required?

Answer options

• A. Full interruption test
• B. Tabletop test
• C. Parallel test
• D. Simulation test

Correct answer: C

Explanation

The correct answer is C, as a parallel test allows for the backup site to be operational while the primary site is still running, ensuring continuous uptime. The other options, such as a full interruption test, would halt operations at the primary site, making it unsuitable for scenarios requiring constant availability.
