CAS-004 Practice Online

Dion Training is analyzing their student practice exam experience. During the analysis, the staff measured the current resiliency of the system by calculating the MTTR and MTBF for the system. The MTTR was measured at 9.1 hours and the MTBF was measured at 3.2 years. Susan, the Chief Operations Officer, stated that the MTTR should be at most 4 hours and the MTBF should be at least 4 years. The team at Dion Training will use all of these measurements and goals to create a technical implementation plan to reach Susan’s requirements. Based on the measurements and goals provided, which of the following types of analysis has the team at Dion Training just performed?
