RedHat EX200 Practice Test 87

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?

  1. Capture desired default target in baseline compliance checks.
  2. Document the runtime identity for scheduled operations.
  3. Monitor synchronization status and time-source failures.
  4. Record temporary target switches separately from permanent defaults.

Explanation

Correct Answer

D:

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

A:

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.

B:

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.

C:

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.

Question 861

Original unofficial RHEL 10 RHCSA skill-check scenario: A configuration audit checks whether a systemd target symlink exists but ignores which target it actually names. Which action best addresses this situation?

  1. Set the supported default to `multi-user.target` and validate on a controlled reboot.
  2. Enable the appropriate systemd service and verify it remains active after reboot.
  3. Enable and start `atd` under approved service policy and verify the queued task.
  4. Query `systemctl get-default` and inspect the resolved target against the baseline.

Explanation

Correct Answer

D:

In this RHEL 10 system administration case: A configuration audit checks whether a systemd target symlink exists but ignores which target it actually names. Underlying reason: The default target is expressed through a symbolic link to a unit target. The most direct, approved resolution is: Query `systemctl get-default` and inspect the resolved target against the baseline. Confirm it by checking: Default boot selection matches the documented role. Sustain the fix by: Validate resolved targets, not just path existence. 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:

Set the supported default to `multi-user.target` and validate on a controlled reboot. That is not sufficient for the reported RHEL task, because the default target is expressed through a symbolic link to a unit target.

B:

Question 862

Original unofficial RHEL 10 RHCSA skill-check scenario: A configuration audit checks whether a systemd target symlink exists but ignores which target it actually names. Which observation best confirms the intended outcome?

  1. `systemctl get-default` reports multi-user and no display manager is required.
  2. `systemctl is-enabled` shows enabled and the service starts following restart.
  3. The queued job executes at the intended time and records its outcome.
  4. Default boot selection matches the documented role.

Question 863

Original unofficial RHEL 10 RHCSA skill-check scenario: A configuration audit checks whether a systemd target symlink exists but ignores which target it actually names. Which system administration principle best explains this behavior?

  1. The default target determines the system's ordinary boot service set.
  2. The default target is expressed through a symbolic link to a unit target.
  3. Starting a unit now and enabling it at boot are separate operations.
  4. A queued job requires the scheduling service to run.

  1. Validate resolved targets, not just path existence.
  2. Capture desired default target in baseline compliance checks.
  3. Check both active and enabled state during commissioning.
  4. Monitor scheduler status before relying on queued maintenance.

Question 865

Original unofficial RHEL 10 RHCSA skill-check scenario: A branch server's logs disagree with other systems by several minutes because chrony has no reachable time source. Which action best addresses this situation?

  1. Verify source reachability and approve the necessary NTP client traffic without exposing unrelated services.
  2. Enable and start `atd` under approved service policy and verify the queued task.
  3. Configure approved NTP sources in chrony and verify synchronization using `chronyc sources` and `tracking`.
  4. Identify the masked dependency and restore it only when approved and appropriate for host policy.

Explanation

Correct Answer

C:

In this RHEL 10 system administration case: A branch server's logs disagree with other systems by several minutes because chrony has no reachable time source. Underlying reason: Time clients require reachable, trusted sources to discipline the system clock. The most direct, approved resolution is: Configure approved NTP sources in chrony and verify synchronization using `chronyc sources` and `tracking`. Confirm it by checking: Time offset converges and sources report usable synchronization. Sustain the fix by: Monitor synchronization status and time-source failures.

  1. Time offset converges and sources report usable synchronization.
  2. Chrony reports a usable source and authentication timestamps stabilize.
  3. The queued job executes at the intended time and records its outcome.
  4. Dependencies activate and the application reaches active state after reboot.

  1. Time clients require reachable, trusted sources to discipline the system clock.
  2. Network restrictions can prevent an otherwise configured time client from synchronizing.
  3. A queued job requires the scheduling service to run.
  4. A masked unit cannot be started by normal dependency resolution.

Explanation

Question 869

Original unofficial RHEL 10 RHCSA skill-check scenario: An administrator manually sets the correct clock but the system drifts again after several days. Which action best addresses this situation?

  1. Enable and configure the supported chrony time service for ongoing synchronization.
  2. Compare absolute time and synchronization status separately from local timezone presentation.
  3. Inspect `systemctl status` and `journalctl -u` to correct the unit's executable path.
  4. Verify subscription or content access status and configure the authorized repository source before updating.

Explanation

Correct Answer

A:

In this RHEL 10 system administration case: An administrator manually sets the correct clock but the system drifts again after several days. Underlying reason: One-time clock correction does not provide continuous time discipline. The most direct, approved resolution is: Enable and configure the supported chrony time service for ongoing synchronization. Confirm it by checking: Clock offset remains within the defined tolerance over repeated checks. Sustain the fix by: Validate time-client service after 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

B:

Compare absolute time and synchronization status separately from local timezone presentation. That is not sufficient for the reported RHEL task, because one-time clock correction does not provide continuous time discipline.

Question 870

Original unofficial RHEL 10 RHCSA skill-check scenario: An administrator manually sets the correct clock but the system drifts again after several days. Which observation best confirms the intended outcome?

  1. Events align when converted to a common timezone and the clocks report healthy sync.
  2. Clock offset remains within the defined tolerance over repeated checks.
  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.
