CompTIA Server+ SK0-005 Practice Question
A systems administrator has just completed an in-place upgrade of the operating system on a server that hosts a critical, custom-developed business application. After the mandatory post-upgrade reboot, the administrator discovers that the application's primary service will not start, preventing users from accessing it. Initial checks show the OS itself is running without errors, and network connectivity is fine. The administrator confirmed a snapshot of the virtual server was taken just before the upgrade process began. Which of the following is the MOST appropriate next action to restore service?
Attempt to reinstall the custom application on the newly upgraded OS.
Edit the application's configuration files to point to new OS library paths.
Revert the server to the snapshot taken immediately before the upgrade.
Contact the application vendor's technical support for an immediate patch.
