• Question 1160:

  The management team has instituted a 48-hour RTO as part of the disaster recovery plan. Which of the following procedures would meet the policy's requirements?

  A. Recover all systems to a loss of 48 hours of data.

  B. Limit the network downtime to a maximum of 48 hours per year.

  C. Recover all systems within 48 hours.

  D. Require 48 hours of system backup maintenance.

  Correct Answer: C

  Recovery time objective (RTO) is the period following a disaster that an individual IT system may remain offline. This represents the maximum amount of time allowed to identify that there is a problem and then perform recovery (restore from backup or switch in an alternative system, for instance).
