In which of the following tests of the recovery plan are the industry workers mobilized to an alternative site to perform actual recovery process?

The correct choice relates to a functional drill/parallel test, which is specifically designed to evaluate the recovery plan in a realistic setting. In this test, industry workers are mobilized to an alternative site to actively engage in the recovery process as it would occur in a real disaster scenario. This hands-on approach allows participants to apply their knowledge, identify any gaps, and make necessary adjustments to the recovery plan, ensuring readiness in the event of an actual incident.

In contrast, other options do not facilitate the same level of practical experience. A full-interruption/full-scale test simulates a complete interruption to operations but often involves a considerable amount of time and resources, making it impractical for frequent use. A tabletop exercise/structured walk-through test primarily focuses on discussion and review rather than physical mobilization or performance of actual recovery tasks. Lastly, a walk-through drill/simulation test is more about theoretical understanding, with less emphasis on executing the recovery in a real-world scenario. Therefore, the functional drill/parallel test is the choice that best represents the mobilization of personnel to an alternative site to practice recovery processes effectively.
