Certified Information Systems Auditor (CISA) — Question 1051

Which of the following practices associated with capacity planning provides the GREATEST assurance that future incidents related to existing server performance will be prevented?

Answer options

• A. Duplicating existing disk drive systems to improve redundancy and data storage
• B. Reviewing results from simulated high-demand stress test scenarios
• C. Performing a root cause analysis for past performance incidents
• D. Anticipating current service level agreements (SLAs) will remain unchanged

Correct answer: B

Explanation

Option B is the correct answer because reviewing results from simulated high-demand stress tests allows for proactive identification of potential performance issues under stress. Options A, C, and D do not directly address future performance under anticipated demands, thus providing less assurance in preventing incidents.
