= Developing the test plan is the task that should be performed once a disaster recovery plan (DRP) has been developed. The test plan is a document that describes the objectives, scope, methods, and procedures for testing the DRP. The test plan should also define the roles and responsibilities of the test team, the test scenarios and criteria, the test schedule and resources, and the test reporting and evaluation. The purpose of testing the DRP is to verify its effectiveness, identify any gaps or weaknesses, and improve its reliability and usability. Testing the DRP also helps to increase the awareness and readiness of the staff and stakeholders involved in the disaster recovery process. Analyzing the business impact, defining response team roles, and identifying recovery time objectives (RTOs) are all tasks that should be performed before developing the DRP, not after. These tasks are part of the business continuity planning (BCP) process, which aims to identify the critical business functions and assets, assess the potential threats and impacts, and determine the recovery strategies and requirements. The DRP is a subset of the BCP that focuses on restoring the IT systems and services after a disaster. Therefore, the DRP should be based on the results of the BCP process, and tested after it has been developed. References = CISM Review Manual 2023, page 218 1; CISM Practice Quiz 2
