The recovery time objective (RTO) is reached at which of the following milestones?

A.
Disaster declaration

B.
Recovery of the backups

C.
Restoration of the system

D.
Return to business as usual processing

Explanation:

The recovery time objective (RTO) is based on the amount of time required to restore a system;
disaster declaration occurs at the beginning of this period. Recovery of the backups occurs shortly
after the beginning of this period. Return to business as usual processing occurs significantly later

than the RTO. RTO is an “objective,” and full restoration may or may not coincide with the RTO.
RTO can be the minimum acceptable operational level, far short of normal operations.
