The BEST way to evaluate the effectiveness of a disaster recovery plan (DRP) is to review the test plan and the results of past tests. Option A is, therefore, the correct answer.
Explanation: A disaster recovery plan (DRP) is a documented process or set of procedures that help an organization to recover from an unexpected disaster or disruption. DRP is a critical part of business continuity planning (BCP), which ensures that a company can continue to operate even after an adverse event. The primary objective of DRP is to minimize the negative impact of a disaster or disruption on the organization's critical business functions.
To ensure that a DRP is effective, it must be tested regularly. A test plan outlines the testing approach and the steps that must be followed during the testing process. The test plan also describes the expected outcomes of the test, including the recovery time objectives (RTO) and recovery point objectives (RPO).
To evaluate the effectiveness of a DRP, an IS auditor should review the test plan and the results of past tests. This will help the auditor to determine whether the DRP is up-to-date and whether it meets the organization's recovery objectives. The IS auditor should also check whether the testing process is comprehensive enough to identify potential weaknesses in the plan.
Option B, plans and procedures in the business continuity plan (BCP), is incorrect because the question is specifically asking about the evaluation of the DRP, not the BCP. While a DRP is a part of BCP, the question is concerned only with the DRP.
Option C, capacity of backup facilities, is incorrect because it is only one part of the DRP, and reviewing this alone would not provide a comprehensive evaluation of the effectiveness of the DRP.
Option D, hardware and software inventory, is incorrect because it is not directly related to the evaluation of a DRP's effectiveness. While hardware and software inventory can be important in the context of a DRP, reviewing this alone would not provide a comprehensive evaluation of the effectiveness of the DRP.
