CompTIA CASP+ (CAS-004) — Question 481

In support of disaster recovery objectives, a third party agreed to provide 99.999% uptime. Recently, a hardware failure impacted a perimeter firewall, without service degradation. Which of the following resiliency concepts was most likely in place?

Answer options

• A. Clustering
• B. High availability
• C. Redundancy
• D. Replication

Correct answer: C

Explanation

Redundancy ensures that if one component fails, another can take over, preventing service disruption. In this case, since the firewall experienced a hardware failure without any service degradation, redundancy was likely in place. Clustering, high availability, and replication may enhance uptime but do not specifically address the hardware failure scenario as effectively as redundancy does.
