CISM study material · question 878 of 1000

Which quantity does recovery point objective express?

  1. The interval between backups
  2. Tolerable downtime, as the total length of the outage that the business process owner is willing to accept
  3. The time that is taken to restore an affected resource back into service after the outage has begun
  4. Tolerable data loss, as the point in time before the outage to which data can be restored
Show the answer

Answer: D. Tolerable data loss, as the point in time before the outage to which data can be restored

SP 800-34r1 fixes the recovery point objective at a moment before the disruption — how far back the data can be brought from backup — making it a statement about data lost, not time lost.
