Which of the following BEST helps to ensure disaster recovery staff members are able to complete their assigned tasks effectively during a disaster?

Performing parallel disaster recovery testing validates the systems and processes, but does not focus as directly on staff training and decision-making skills as tabletop exercises.

Documenting the order of system and application restoration provides a critical reference, but it doesn't ensure staff comprehension or ability to execute the steps effectively without practice.

Involving disaster recovery staff members in risk assessments contributes to their understanding of risks but is not the primary mechanism for hands-on preparation for DRP execution.

Tabletop exercises and scenario analysis provide a controlled environment for staff to walk through the DRP, understand their roles, practice decision-making, and identify potential gaps without the pressure of a real event. This practice significantly enhances their preparedness, coordination, and ability to respond effectively when a disaster strikes.
