Certified Information Systems Security Professional (CISSP) — Question 15

A security architect is reviewing plans for an application with a Recovery Point Objective (RPO) of 15 minutes. The current design has all of the application infrastructure located within one co-location data center. Which security principle is the architect currently assessing?

Answer options

• A. Disaster recovery (DR)
• B. Availability
• C. Redundancy
• D. Business continuity (BC)

Correct answer: B

Explanation

The correct answer is B, Availability, because the architect must ensure the application can be accessed and operational within the defined RPO. While Disaster recovery (A), Redundancy (C), and Business continuity (D) are important aspects of overall security, they do not specifically address the immediate need for the application's availability within the 15-minute timeframe.
