During a tabletop exercise, team members come together and walk through a scenario without making any changes to information systems, so that is not our correct answer here. In a parallel test, the team actually activates the disaster recovery site for testing, but the primary site remains operation-al, which is not what we are looking for. The checklist review is the least disruptive type of disaster recovery test. During a checklist review, team members each review the contents of their disaster recovery checklists on their own and suggest any necessary changes. During a full interruption test, the team takes down the primary site and confirms that the disaster recovery site is capable of handling regular operations. The full interruption test is the most thorough test but also the most disruptive, making it another incorrect answer.
