Certified Information Systems Auditor (CISA) — Question 703

Which of the following BEST addresses the availability of an online store?

Answer options

• A. Online backups
• B. A mirrored site at another location
• C. Clustered architecture
• D. RAID level 5 storage devices

Correct answer: C

Explanation

The correct answer, clustered architecture, provides high availability by distributing workloads across multiple servers, ensuring that if one fails, others can take over. While online backups, mirrored sites, and RAID level 5 enhance data protection and recovery, they do not directly ensure continuous availability like clustered architecture does.
