Which testing approach represents a realistic end-to-end drill that may involve red teams?

• A. Full Simulation
• B. Tabletop
• C. Mock
• D. Checklist Review

Answer: (A)

A full simulation is a live, end-to-end drill that tests the entire incident response chain—from initial detection through containment, eradication, and recovery—under realistic conditions. It often involves red teams acting as attackers to mimic real adversaries, pushing people, processes, and technology to respond as they would in a real incident. This level of realism validates how well runbooks are followed, how escalation and communications work, and how tools and teams coordinate under pressure, giving a true measure of readiness.

Tabletop exercises are discussion-based and don’t involve active systems or live operations, so they don’t test actual responses in a real environment. Mock scenarios can be limited in scope and may not exercise the full sequence of events or cross-team collaboration. Checklist reviews focus on whether controls exist on paper rather than on how they perform in practice.
