In which type of disaster recovery test do team members formally review the disaster recovery plan together?

1. Read-through

2. Walk-through

3. Parallel Test

4. Full interruption test

The correct answer is: Walk-through

A walk-through test is a structured activity where team members gather to review the disaster recovery plan and discuss their roles and responsibilities in case of a disaster. In this setting, participants can collaborate to ensure that everyone understands the plan, the procedures to follow, and identify any gaps or outdated information in the document. This type of testing helps foster communication among team members and reinforces their preparedness without performing any actual recovery operations. The other types of tests serve different purposes. A read-through is typically a less formal discussion of the plan without active participation or role-playing, which does not promote the same level of engagement and evaluation. A parallel test involves running backup systems alongside the primary systems to validate the recovery process rather than just reviewing it, while a full interruption test entails shutting down the primary systems and executing the full recovery plan, which is more of a practical exercise than a review. Therefore, the walk-through method stands out as the effective forum for collaborative review and analysis of the disaster recovery plan.
