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

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 the 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.
