An organization wants to conduct some of the disaster recovery plan testing with the least...

Tabletop testing is the disaster recovery testing method with the least impact on production systems. Managing Cloud guidance explains that tabletop exercises are discussion-based scenarios where stakeholders walk through response procedures without executing actual system changes.

This approach allows teams to validate roles, responsibilities, communication paths, and decision-making processes. Tabletop testing is cost-effective, low-risk, and ideal for early validation of disaster recovery and business continuity plans.

Dry runs and full tests involve actual system actions and can impact production. Unit testing focuses on individual components. Therefore, tabletop testing is the correct answer.
