An organization having a number of offices across a wide geographical area has developed a disaster
recovery plan. Using actual resources, which of the following is the MOST cost-effective test of the
disaster recovery plan?

A.
Full operational test

B.
Preparedness test

C.
Paper test

D.
Regression test

Explanation:
A preparedness test is performed by each local office/area to test the adequacy of the preparedness
of local operations for disaster recovery. A paper test is a structured walk-through of the disaster
recovery plan and should be conducted before a preparedness test. A full operational test is
conducted after the paper and preparedness test. A regression test is not a disaster recovery
planning (DRP) test and is used in software maintenance.
