Question 860
Original unofficial RHEL 10 RHCSA skill-check scenario: An administrator uses `systemctl isolate rescue.target` for an urgent task and assumes the persistent default target changed. Which ongoing practice best prevents a recurrence?
Explanation
Correct Answer
In this RHEL 10 system administration case: An administrator uses `systemctl isolate rescue.target` for an urgent task and assumes the persistent default target changed. Underlying reason: Isolating a target changes runtime services without automatically selecting the next boot's target. The most direct, approved resolution is: Distinguish a one-time target isolation from `systemctl set-default` and set only the intended permanent default. Confirm it by checking: The system's current and next-boot target behavior match the approved plan. Sustain the fix by: Record temporary target switches separately from permanent defaults. 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
Capture desired default target in baseline compliance checks. That is not sufficient for the reported RHEL task, because isolating a target changes runtime services without automatically selecting the next boot's target.
Document the runtime identity for scheduled operations. That is not sufficient for the reported RHEL task, because isolating a target changes runtime services without automatically selecting the next boot's target.
Monitor synchronization status and time-source failures. That is not sufficient for the reported RHEL task, because isolating a target changes runtime services without automatically selecting the next boot's target.
