RedHat EX200 Practice Test 84

Question 830

Original unofficial RHEL 10 RHCSA skill-check scenario: An engineer assumes starting a timer guarantees the associated service succeeded. Which observation best confirms the intended outcome?

  1. The listed next trigger reflects the new schedule.
  2. The selected packages update and application postchecks pass.
  3. The service completed successfully at its scheduled activation time.
  4. `is-active` and `is-enabled` both reflect the intended stopped, disabled state.

Explanation

Correct Answer

C:

In this RHEL 10 system administration case: An engineer assumes starting a timer guarantees the associated service succeeded. Underlying reason: Timer activation and service execution success are separate states. The most direct, approved resolution is: Check both the timer activation and the triggered service's journal and exit status. Confirm it by checking: The service completed successfully at its scheduled activation time. Sustain the fix by: Monitor triggered unit results in addition to the next-run schedule. This is the INTENDED response for the strongest objective verification result. It is a knowledge-check explanation, not a verified hands-on Red Hat exam answer;

Incorrect Answers

A:

The listed next trigger reflects the new schedule. That is not sufficient for the reported RHEL task, because timer activation and service execution success are separate states.

B:

The selected packages update and application postchecks pass. That is not sufficient for the reported RHEL task, because timer activation and service execution success are separate states.

D:

`is-active` and `is-enabled` both reflect the intended stopped, disabled state. That is not sufficient for the reported RHEL task, because timer activation and service execution success are separate states.

Question 831

Original unofficial RHEL 10 RHCSA skill-check scenario: An engineer assumes starting a timer guarantees the associated service succeeded. Which system administration principle best explains this behavior?

  1. Timer activation and service execution success are separate states.
  2. Systemd managers cache loaded unit definitions until reloaded.
  3. Dependency changes and running processes can require more than package installation.
  4. Disabling controls future startup rather than automatically stopping active processes.

Question 832

Original unofficial RHEL 10 RHCSA skill-check scenario: An engineer assumes starting a timer guarantees the associated service succeeded. Which ongoing practice best prevents a recurrence?

  1. Include daemon-reload in unit update procedures.
  2. Require transaction review and service acceptance checks.
  3. Monitor triggered unit results in addition to the next-run schedule.
  4. Test current and future unit behavior independently.

Question 833

Original unofficial RHEL 10 RHCSA skill-check scenario: A new web application is running after a manual start but disappears after the first host restart. Which action best addresses this situation?

  1. Reload the systemd manager before restarting the affected unit under change control.
  2. Inspect the service's runtime identity, target directory ownership and allowed access.
  3. Identify the correct kernel entry and apply the supported bootloader change only to the intended target.
  4. Enable the appropriate systemd service and verify it remains active after reboot.

Explanation

Correct Answer

D:

In this RHEL 10 system administration case: A new web application is running after a manual start but disappears after the first host restart. Underlying reason: Starting a unit now and enabling it at boot are separate operations. The most direct, approved resolution is: Enable the appropriate systemd service and verify it remains active after reboot. Confirm it by checking: `systemctl is-enabled` shows enabled and the service starts following restart. Sustain the fix by: Check both active and enabled state during commissioning. 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:

Reload the systemd manager before restarting the affected unit under change control. That is not sufficient for the reported RHEL task, because starting a unit now and enabling it at boot are separate operations.

Question 834

Original unofficial RHEL 10 RHCSA skill-check scenario: A new web application is running after a manual start but disappears after the first host restart. Which observation best confirms the intended outcome?

  1. The effective unit properties reflect the new drop-in and the service starts cleanly.
  2. The application writes logs under its approved identity without broad filesystem permission changes.
  3. `systemctl is-enabled` shows enabled and the service starts following restart.
  4. Boot entry inspection shows the argument on the selected kernel and no unrelated entry is modified.
