Certified Information Security Manager (CISM) — Question 696

An organization has just updated its backup capability to a new cloud-based solution. Which of the following tests will MOST effectively verify this change is working as intended?

Answer options

• A. Simulation testing
• B. Tabletop testing
• C. Parallel testing
• D. Black box testing

Correct answer: C

Explanation

Parallel testing is the most effective way to verify the new cloud-based backup solution because it involves running the new system alongside the old one to ensure both are functioning correctly. Simulation testing, tabletop testing, and black box testing are useful in their own contexts but do not provide the direct comparison and validation of data integrity that parallel testing offers.
