CompTIA Server+ SK0-005 Practice Question
A systems administrator is responsible for a fleet of virtual servers. After receiving approval from the Change Advisory Board (CAB), the administrator successfully applies a critical operating system patch to a production web server during a scheduled maintenance window. Post-change testing confirms that the server is online and web services are functioning as expected. What is the final and most crucial step the administrator must perform to complete the change management process?
Initiate a new vulnerability scan to confirm the patch resolved the security issue.
Update all relevant documentation, including the server's configuration baseline and the change management record.
Send a closure notification to all stakeholders and end users.
Decommission the pre-change snapshot of the virtual machine.
