Explanation: A checklist test is a test in which the disaster recovery checklists are distributed to the members of the disaster recovery team. All members are asked to review the assigned checklist. The checklist test is a simple test and it is easy to conduct this test. It allows to accomplish the following three goals: It ensures that the employees are aware of their responsibilities and they have the refreshed knowledge. It provides an individual with an opportunity to review the checklists for obsolete information and update any items that require modification during the changes in the organization. It ensures that the assigned members of disaster recovery team are still working for the organization. Answer: B is incorrect. A simulation test is a method used to test the disaster recovery plans. It operates just like a structured walk- through test. In the simulation test, the members of a disaster recovery team present with a disaster scenario and then, discuss on appropriate responses. These suggested responses are measured and some of them are taken by the team. The range of the simulation test should be defined carefully for avoiding excessive disruption of normal business activities. Answer: A is incorrect. A parallel test includes the next level in the testing procedure, and relocates the employees to an alternate recovery site and implements site activation procedures. These employees present with their disaster recovery responsibilities as they would for an actual disaster. The disaster recovery sites have full responsibilities to conduct the day-to-day organization’s business. Answer: C is incorrect. A full-interruption test includes the operations that shut down at the primary site and are shifted to the recovery site according to the disaster recovery plan. It operates just like a parallel test. The full-interruption test is very expensive and difficult to arrange. Sometimes, it causes a major disruption of operations if the test fails.
