CompTIA Server+ SK0-005 Practice Question
A systems administrator is troubleshooting a Linux server that hosts a critical web application. After a scheduled automated security patch was applied overnight, users are reporting that the application is inaccessible this morning. The administrator confirms the server is online and they can log in, but the primary web service daemon is not running. A systemctl status
command on the service only shows a generic "failed" state. To determine the root cause of the service failure, what is the most appropriate next step for the administrator to take?
Review the system's log files, such as the output from
journalctl
, for specific error messages from the web service.Attempt to replicate the issue by applying the same patch to a staging server with an identical configuration.
Consult the hardware vendor's compatibility list (HCL) to ensure the server's components are supported by the new patch.
Immediately roll back the security patch using the package manager and restart the server.
