Question 840
Original unofficial RHEL 10 RHCSA skill-check scenario: An operator changes a service drop-in file but restarts the daemon without reloading systemd's unit definitions. Which ongoing practice best prevents a recurrence?
Explanation
Correct Answer
In this RHEL 10 system administration case: An operator changes a service drop-in file but restarts the daemon without reloading systemd's unit definitions. Underlying reason: Systemd uses loaded unit metadata that may be stale after file edits. The most direct, approved resolution is: Reload the systemd manager before restarting the affected unit under change control. Confirm it by checking: The effective unit properties reflect the new drop-in and the service starts cleanly. Sustain the fix by: Include `daemon-reload` when changing unit configuration. This is the INTENDED response for the best ongoing operational safeguard. It is a knowledge-check explanation, not a verified hands-on Red Hat exam answer;
Incorrect Answers
Validate executable locations in unit deployment tests. That is not sufficient for the reported RHEL task, because systemd uses loaded unit metadata that may be stale after file edits.
Review schedules when decommissioning scripts. That is not sufficient for the reported RHEL task, because systemd uses loaded unit metadata that may be stale after file edits.
Require a job-list check before canceling scheduled work. That is not sufficient for the reported RHEL task, because systemd uses loaded unit metadata that may be stale after file edits.
