Support Vendor's Server Hard Drive Replacement Time: Analysis and Conclusions

AD.

In this scenario, the security analyst is updating a Business Impact Analysis (BIA) document. The BIA document helps organizations to identify critical systems, processes, and functions, and prioritize them based on their importance to the organization. The BIA also helps organizations to understand the impact of a disruption or outage to these critical systems, processes, and functions.

The security analyst noticed that the support vendor's time to replace a server hard drive has improved from eight hours to two hours. Based on this information, the following conclusions can be made:

1. The Mean Time To Repair (MTTR) has improved/faster: MTTR is a measure of the average time it takes to repair a system or component after it has failed. In this scenario, the time it takes to replace a server hard drive has reduced from eight hours to two hours. This means that the MTTR has improved, which is good news for the organization.

2. The Recovery Time Objective (RTO) has decreased: RTO is the maximum amount of time it takes for a business process to be restored after a disruption. In this scenario, the time it takes to replace a server hard drive has reduced from eight hours to two hours. This means that the RTO has decreased, which is also good news for the organization.

Therefore, the correct conclusions are that the MTTR has improved/faster, and the RTO has decreased. Option A and D are the correct answers.

MTTF (Mean Time To Failure) is a measure of the average time it takes for a component or system to fail. There is no information given in the scenario about MTTF, so options E and F are not applicable.
