Which of the following disaster recovery tests includes the operations that shut down at the primary site, and are shifted to the recovery site according to the disaster recovery plan?

A. B. C. D.C.
The disaster recovery test that involves shutting down operations at the primary site and shifting them to the recovery site according to the disaster recovery plan is called a "Full-interruption test."
A Full-interruption test is also known as a "Cutover Test" or "Disaster Recovery Exercise." It is the most comprehensive and complex type of disaster recovery test and involves the complete shutdown of primary operations to verify that the recovery site can handle the full workload. The goal of this test is to simulate a complete disaster scenario, and assess the ability of the recovery site to take over the operations, restore the systems, and continue operations in the event of a disaster.
During a Full-interruption test, all primary operations are suspended, and the recovery site takes over all functions, including data processing, transaction processing, and communications. The test may last from a few hours to several days, depending on the scope and complexity of the systems and processes involved.
The Full-interruption test is a critical component of the disaster recovery planning process, as it helps to identify potential issues and vulnerabilities in the disaster recovery plan, including operational risks, data loss, and security breaches. By conducting this test, organizations can evaluate the effectiveness of their disaster recovery plan and make necessary adjustments to ensure that they can quickly and effectively recover from a disaster.
In contrast, the other disaster recovery tests listed in the question are:
A. Structured walk-through test - a test that involves the review of the disaster recovery plan by a team of experts to identify potential issues, gaps, and deficiencies.
B. Simulation test - a test that involves the simulation of a disaster scenario to assess the effectiveness of the disaster recovery plan and the readiness of the recovery team.
D. Parallel test - a test that involves running both primary and recovery site simultaneously to ensure that the recovery site can handle the workload and maintain data consistency.
