Certified Information Systems Auditor (CISA) — Question 280

Which of the following is an IS auditor's BEST recommendation to help an organization increase the efficiency of computing resources?

Answer options

• A. Hardware upgrades
• B. Real-time backups
• C. Virtualization
• D. Overclocking the central processing unit (CPU)

Correct answer: C

Explanation

The correct answer is C, as virtualization allows multiple virtual machines to run on a single physical server, maximizing resource utilization and efficiency. Options A (hardware upgrades) may increase performance but are not as efficient as virtualization in resource management. Option B (real-time backups) ensures data safety but does not directly enhance resource efficiency, while option D (overclocking) can lead to potential hardware damage and instability rather than improving overall resource utilization.
