Options

- BIdentifying the benchmark required for restoration

Explanation
The primary purpose of testing a Disaster Recovery Plan is to validate that it will actually work as intended when a real disaster occurs, confirming that recovery objectives and procedures are achievable.
Common mistakes.
- A. Evaluating efficiency focuses on optimizing speed and resource usage, which is a secondary benefit of testing, not the primary purpose - a plan can be efficient yet still fail to restore critical systems correctly.
- B. Identifying benchmarks for restoration is an activity that should occur during the planning phase (e.g., defining RTO/RPO), not the primary reason for conducting DRP tests.
- D. The Recovery Time Objective (RTO) is defined during the Business Impact Analysis (BIA) phase before the DRP is written, so testing is not the mechanism used to determine it.
