CompTIA Cloud+ (CV0-002) — Question 163

Before doing a change on a VM, a systems administrator wants to ensure there is an easy and fast way to rollback if needed. The change and testing should take approximately two hours. Which of the following is the EASIEST way to meet this requirement?

Answer options

• A. Create a snapshot on the hypervisor.
• B. Make an on-demand, incremental backup to a VTL.
• C. Make an on-demand, full backup to a secondary location.
• D. Create a snapshot on a remote storage array.

Correct answer: A

Explanation

The easiest method to ensure a quick rollback is to create a snapshot on the hypervisor, as this allows immediate restoration to the previous state without extensive time or resource investment. Options B and C involve more complex backup processes that take longer and may not provide instant recovery. Option D, while also creating a snapshot, may involve additional latency due to remote access.
