Which type of disaster recovery test is conducted to check the functionality of the disaster recovery plan without disrupting operations?

  1. Full interruption test

  2. Parallel Test

  3. Simulation

  4. Walk-through

The correct answer is: Parallel Test

The choice of a parallel test is significant because it allows organizations to validate the functionality of their disaster recovery plan in a manner that does not interfere with daily operations. In a parallel test, the recovery processes are executed in a controlled environment that runs alongside the active system, enabling the testing team to observe and assess the effectiveness of the recovery procedures without impacting normal business activities. This approach is particularly beneficial because it mimics a real disaster recovery scenario while still ensuring that the primary operations continue to run smoothly. Consequently, any issues that arise during the test can be identified and addressed without risking the operational integrity of the organization. In contrast, certain other testing types may involve disruption to services. For instance, a full interruption test would involve shutting down the primary system to simulate a disaster, directly impacting ongoing operations. A simulation test is a theoretical exercise or role-play scenario where team members participate in a disaster recovery situation without actual implementation, which may also not yield practical validation of the plan. A walk-through typically involves a review of the plans and procedures but does not execute any aspect of the disaster recovery process, thus lacking the operational testing component. Therefore, a parallel test stands out as the most effective method to ensure that the disaster recovery plan can be deployed successfully without
