RedHat EX200 Practice Test 85

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?

  1. Validate executable locations in unit deployment tests.
  2. Review schedules when decommissioning scripts.
  3. Include `daemon-reload` when changing unit configuration.
  4. Require a job-list check before canceling scheduled work.

Explanation

Correct Answer

C:

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

A:

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.

B:

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.

D:

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.

Question 841

Original unofficial RHEL 10 RHCSA skill-check scenario: A service fails repeatedly with a wrong executable path while the team blames the network firewall. Which action best addresses this situation?

  1. Stop the unit for current state and disable it separately if it must not start automatically.
  2. Check both the timer activation and the triggered service's journal and exit status.
  3. Verify subscription or content access status and configure the authorized repository source before updating.
  4. Inspect `systemctl status` and `journalctl -u` to correct the unit's executable path.

Explanation

Correct Answer

D:

In this RHEL 10 system administration case: A service fails repeatedly with a wrong executable path while the team blames the network firewall. Underlying reason: A unit's ExecStart path must resolve before networking policy matters. The most direct, approved resolution is: Inspect `systemctl status` and `journalctl -u` to correct the unit's executable path. Confirm it by checking: The service starts and no executable-not-found errors appear. Sustain the fix by: Validate executable locations in unit deployment tests. This is the INTENDED response for the best approved troubleshooting or configuration action. It is a knowledge-check explanation, not a verified hands-on Red Hat exam answer;

Incorrect Answers

A:

Stop the unit for current state and disable it separately if it must not start automatically. That is not sufficient for the reported RHEL task, because a unit's ExecStart path must resolve before networking policy matters.

Question 842

Original unofficial RHEL 10 RHCSA skill-check scenario: A service fails repeatedly with a wrong executable path while the team blames the network firewall. Which observation best confirms the intended outcome?

  1. `is-active` and `is-enabled` both reflect the intended stopped, disabled state.
  2. The service completed successfully at its scheduled activation time.
  3. The service starts and no executable-not-found errors appear.
  4. DNF resolves the supported updates and the installed package versions change as approved.

Question 843

Original unofficial RHEL 10 RHCSA skill-check scenario: A service fails repeatedly with a wrong executable path while the team blames the network firewall. Which system administration principle best explains this behavior?

  1. Disabling controls future startup rather than automatically stopping active processes.
  2. Timer activation and service execution success are separate states.
  3. A unit's ExecStart path must resolve before networking policy matters.
  4. Package updates require reachable trusted content sources and appropriate access rights.

Question 844

Original unofficial RHEL 10 RHCSA skill-check scenario: A service fails repeatedly with a wrong executable path while the team blames the network firewall. Which ongoing practice best prevents a recurrence?

  1. Test current and future unit behavior independently.
  2. Monitor triggered unit results in addition to the next-run schedule.
  3. Validate executable locations in unit deployment tests.
  4. Check repository access before security patch windows.

Question 845

Original unofficial RHEL 10 RHCSA skill-check scenario: A system administrator disables an application unit to stop it immediately and assumes no process remains running. Which action best addresses this situation?

  1. Stop the unit for current state and disable it separately if it must not start automatically.
  2. Reload the systemd manager before restarting the affected unit under change control.
  3. Remove or update the obsolete cron entry and verify the active crontab.
  4. Enable and configure the supported chrony time service for ongoing synchronization.

Question 846

Original unofficial RHEL 10 RHCSA skill-check scenario: A system administrator disables an application unit to stop it immediately and assumes no process remains running. Which observation best confirms the intended outcome?

  1. The effective unit properties reflect the new drop-in and the service starts cleanly.
  2. The missing script is no longer invoked and scheduled tasks run normally.
  3. `is-active` and `is-enabled` both reflect the intended stopped, disabled state.
  4. Clock offset remains within the defined tolerance over repeated checks.

Question 847

Original unofficial RHEL 10 RHCSA skill-check scenario: A system administrator disables an application unit to stop it immediately and assumes no process remains running. Which system administration principle best explains this behavior?

  1. Systemd uses loaded unit metadata that may be stale after file edits.
  2. Scheduler entries remain until explicitly removed regardless of target file existence.
  3. Disabling controls future startup rather than automatically stopping active processes.
  4. One-time clock correction does not provide continuous time discipline.

Question 849

Original unofficial RHEL 10 RHCSA skill-check scenario: A headless server enters a graphical login after reboot despite its approved command-line-only configuration. Which action best addresses this situation?

  1. Distinguish a one-time target isolation from `systemctl set-default` and set only the intended permanent default.
  2. Remove or update the obsolete cron entry and verify the active crontab.
  3. Set the supported default to `multi-user.target` and validate on a controlled reboot.
  4. Schedule the one-off command using `at` for the approved time and inspect the pending job list.

Explanation

Correct Answer

C:

In this RHEL 10 system administration case: A headless server enters a graphical login after reboot despite its approved command-line-only configuration. Underlying reason: The default target determines the system's ordinary boot service set. The most direct, approved resolution is: Set the supported default to `multi-user.target` and validate on a controlled reboot. Confirm it by checking: `systemctl get-default` reports multi-user and no display manager is required. Sustain the fix by: Capture desired default target in baseline compliance checks. This is the INTENDED response for the best approved troubleshooting or configuration action. It is a knowledge-check explanation, not a verified hands-on Red Hat exam answer;

  1. The system's current and next-boot target behavior match the approved plan.
  2. The missing script is no longer invoked and scheduled tasks run normally.
  3. `systemctl get-default` reports multi-user and no display manager is required.
  4. `atq` shows one scheduled execution and no daily recurrence.
