CompTIA Server+ SK0-005 Practice Question
Your organization has a three-hour maintenance window to install the latest cumulative update on a standalone Windows Server 2022 Hyper-V host that runs several mission-critical virtual machines. Change-control policy states that, if the update causes the host to become unbootable, it must be returned to its previous state within the same window. Which preparatory action will provide the fastest and most reliable rollback path while adding the least additional downtime?
Gracefully shut down the virtual machines and create snapshots of each guest before applying the update.
Export the list of installed updates with DISM /Online /Get-Packages so the patch level can be recreated later.
Record the current enabled roles and features with Get-WindowsFeature and attach the report to the change ticket.
Use Windows Server Backup to take and verify a full bare-metal image of the Hyper-V host on external storage.
