CISSP – Information Systems Security Architecture Professional (ISSAP) — Question 34

Which of the following is the duration of time and a service level within which a business process must be restored after a disaster in order to avoid unacceptable consequences associated with a break in business continuity?

Answer options

• A. RCO
• B. RTO
• C. RPO
• D. RTA

Correct answer: B

Explanation

The correct answer is RTO (Recovery Time Objective), which defines the maximum allowable downtime before significant impact occurs. RCO (Recovery Cost Objective) relates to the cost of recovery, RPO (Recovery Point Objective) focuses on data loss tolerance, and RTA (Recovery Time Actual) is not a standard term used in this context.
