RedHat EX200 Practice Test 51

Question 500

Original unofficial RHEL 10 RHCSA skill-check scenario: A server has persistent journald enabled but its designated storage volume is full. Which ongoing practice best prevents a recurrence?

  1. Reconcile logging retention with storage capacity forecasts.
  2. Monitor journal disk use and retention trends.
  3. Coordinate monitoring suppression with scheduled power maintenance.
  4. Track priorities of long-running maintenance tasks.

Explanation

Correct Answer

B:

In this RHEL 10 system administration case: A server has persistent journald enabled but its designated storage volume is full. Underlying reason: Persistent logging depends on storage capacity and configured bounds. The most direct, approved resolution is: Investigate journal disk use and adjust supported size limits or free approved space safely. Confirm it by checking: New journal events continue and retention remains within policy limits. Sustain the fix by: Monitor journal disk use and retention trends. 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:

Reconcile logging retention with storage capacity forecasts. That is not sufficient for the reported RHEL task, because persistent logging depends on storage capacity and configured bounds.

C:

Coordinate monitoring suppression with scheduled power maintenance. That is not sufficient for the reported RHEL task, because persistent logging depends on storage capacity and configured bounds.

D:

Track priorities of long-running maintenance tasks. That is not sufficient for the reported RHEL task, because persistent logging depends on storage capacity and configured bounds.

Question 501

Original unofficial RHEL 10 RHCSA skill-check scenario: An incident response tool queries prior-boot evidence after rotation but uses only the current boot selector. Which action best addresses this situation?

  1. Use supported `journald.conf` limits and deliberate vacuum/rotation under retention policy.
  2. Select a supported workload-appropriate TuneD profile after reviewing the environment.
  3. Inspect available and active `tuned-adm` profiles before selecting an approved performance profile.
  4. Use the appropriate boot offset or boot ID and verify which journal files are available.

Explanation

Correct Answer

D:

In this RHEL 10 system administration case: An incident response tool queries prior-boot evidence after rotation but uses only the current boot selector. Underlying reason: Journal queries select boots explicitly rather than returning history indiscriminately. The most direct, approved resolution is: Use the appropriate boot offset or boot ID and verify which journal files are available. Confirm it by checking: Required historical events from the selected boot are retrieved. Sustain the fix by: Record boot IDs in evidence metadata. 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:

Use supported `journald.conf` limits and deliberate vacuum/rotation under retention policy. That is not sufficient for the reported RHEL task, because journal queries select boots explicitly rather than returning history indiscriminately.

B:

Question 502

Original unofficial RHEL 10 RHCSA skill-check scenario: An incident response tool queries prior-boot evidence after rotation but uses only the current boot selector. Which observation best confirms the intended outcome?

  1. Required historical events from the selected boot are retrieved.
  2. Journal storage fits the approved quota while required historical records remain.
  3. The active profile matches the approved virtual guest policy and metrics remain stable.
  4. `tuned-adm active` reports the intended profile after change.

Question 503

Original unofficial RHEL 10 RHCSA skill-check scenario: An incident response tool queries prior-boot evidence after rotation but uses only the current boot selector. Which system administration principle best explains this behavior?

  1. Persistence without retention limits can grow resource use.
  2. Optimal tuning depends on actual platform and workload rather than a universal setting.
  3. Tuned applies coordinated operating-system settings chosen for workload characteristics.
  4. Journal queries select boots explicitly rather than returning history indiscriminately.

Question 505

Original unofficial RHEL 10 RHCSA skill-check scenario: A compliance host sets excessive journal retention and begins to impact application storage. Which action best addresses this situation?

  1. Use supported `journald.conf` limits and deliberate vacuum/rotation under retention policy.
  2. Investigate journal disk use and adjust supported size limits or free approved space safely.
  3. Query the affected unit with `journalctl -u` and inspect the relevant time window.
  4. Use the approved console and documented boot-menu recovery path rather than resetting disks blindly.

Explanation

Question 506

Original unofficial RHEL 10 RHCSA skill-check scenario: A compliance host sets excessive journal retention and begins to impact application storage. Which observation best confirms the intended outcome?

  1. New journal events continue and retention remains within policy limits.

Question 507

Original unofficial RHEL 10 RHCSA skill-check scenario: A compliance host sets excessive journal retention and begins to impact application storage. Which system administration principle best explains this behavior?

  1. Persistent logging depends on storage capacity and configured bounds.
  2. Systemd journal entries are indexed by unit and may not be obvious in a generic log.
  3. A broken userspace boot can require console-level recovery independent of remote services.
  4. Persistence without retention limits can grow resource use.

Question 509

Original unofficial RHEL 10 RHCSA skill-check scenario: A newly installed SSH daemon is running but does not start after a host reboot. Which action best addresses this situation?

  1. Use an approved encrypted SSH-based transfer such as `scp` or SFTP with host verification.
  2. Enable the `sshd` unit with `systemctl enable --now` and verify its boot behavior.
  3. Use an approved shutdown or reboot window and notify dependent teams before execution.
  4. Filter journal output by unit, priority, and event time before attributing a fault.

Explanation

Correct Answer

B:

In this RHEL 10 system administration case: A newly installed SSH daemon is running but does not start after a host reboot. Underlying reason: Starting a service now does not necessarily make its activation persistent. The most direct, approved resolution is: Enable the `sshd` unit with `systemctl enable --now` and verify its boot behavior. Confirm it by checking: `systemctl is-enabled` reports enabled and SSH returns after reboot. Sustain the fix by: Check both active and enabled states during deployment. 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:

Question 510

Original unofficial RHEL 10 RHCSA skill-check scenario: A newly installed SSH daemon is running but does not start after a host reboot. Which observation best confirms the intended outcome?

  1. The destination checksum matches and the transfer uses an authenticated encrypted connection.
  2. `systemctl is-enabled` reports enabled and SSH returns after reboot.
  3. The system restarts within the window and required service checks pass.
  4. A narrow timeline identifies the relevant service error sequence.
