CISM study material · question 879 of 1000

Why is recovery point objective not counted as part of maximum tolerable downtime, while recovery time objective is?

  1. Because it concerns lost data rather than elapsed outage
  2. Because it applies to backups rather than to systems
  3. Because it is set by the data owner rather than the system owner
  4. Because it is measured in transactions rather than in time
Show the answer

Answer: A. Because it concerns lost data rather than elapsed outage

SP 800-34r1 states that unlike recovery time objective, recovery point objective is not considered part of maximum tolerable downtime — its concern is lost data, not the duration of the outage.
