Which of the following is the most complete disaster recovery plan test type, to be performed after successfully
completing the Parallel test?

A.
Full Interruption test

B.
Checklist test

C.
Simulation test

D.
Structured walk-through test

Explanation:
Full-interruption tests operate like parallel tests, but they involve actually shutting down operations at the
primary site and shifting them to the recovery site. After a parallel test has been completed the next step is to
perform a full-interruption test.
Incorrect Answers:
B: The checklist test is one of the simplest tests to conduct. You should perform it before, after, you perform a
Parallel test.
C: Simulation tests are similar to the structured walk – through tests, and should be performed before parallel
test, after parallel tests.
D: Parallel tests represent the next level in testing compared to a structured walk-through test, not vice versa.
