Final answer:
Tabletop exercises and full-scale rehearsals are two simulations used to test a risk response plan.
Step-by-step explanation:
When testing a risk response plan, two simulations that can be used are tabletop exercises and full-scale rehearsals.
Tabletop exercises are discussions held in a conference room where participants talk through a potential scenario and identify how they would respond to it. The exercise is focused on discussing strategies and plans of action rather than performing actual actions.
Full-scale rehearsals, on the other hand, involve actually implementing the response plan in a real-life scenario. This can include simulating a crisis situation, activating resources, and evaluating the effectiveness of the response plan.
