Certified Information Systems Auditor (CISA) — Question 419

An IS auditor learns the organization has experienced several server failures in its distributed environment. Which of the following is the BEST recommendation to limit the potential impact of server failures in the future?

Answer options

• A. Failover power
• B. Clustering
• C. Parallel testing
• D. Redundant pathways

Correct answer: B

Explanation

Clustering is the most effective method to ensure high availability and minimize downtime during server failures, as it allows multiple servers to work together to handle workloads. Failover power and redundant pathways provide backup for power and connectivity but do not address application availability directly. Parallel testing is unrelated to server reliability and focuses on validating changes before implementation.
