Which of the following disaster recovery tests includes the operations that shut down at the primary site, and are shifted to the recovery site according to the disaster recovery plan?

A structured walk-through test involves reviewing the disaster recovery plan with relevant personnel to identify gaps or inconsistencies, without actually performing any system cutovers.

A full-interruption test, also known as a cutover test, involves completely shutting down the primary site's operations and shifting all production activities to the designated recovery site. This rigorous test validates the entire disaster recovery plan, including data restoration, application recovery, and failover procedures, under conditions that closely mimic a real disaster scenario.

A parallel test involves running critical systems concurrently at both the primary and recovery sites, allowing for comparison of outputs without disrupting primary operations.

A simulation test involves simulating a disaster scenario without actually stopping primary operations, where personnel react as if a disaster occurred and follow the plan's steps up to a certain point without actual system failover.
