Certified Information Systems Auditor (CISA) — Question 1408

Which of the following is the BEST reason for an organization to use clustering?

Answer options

• A. To decrease system response time
• B. To improve the recovery time objective (RTO)
• C. To improve system resiliency
• D. To facilitate faster backups

Correct answer: C

Explanation

The correct answer is C because clustering enhances system resiliency by allowing multiple servers to work together, providing redundancy and failover capabilities. Options A and D focus on specific performance improvements rather than overall system reliability, while B relates to recovery processes, which, while important, do not capture the primary benefit of clustering.
