RedHat EX200 Practice Test 79

Question 780

Original unofficial RHEL 10 RHCSA skill-check scenario: A service uses a bind-mounted directory with mismatched ownership after a deployment. Which ongoing practice best prevents a recurrence?

  1. Test mount-source identity and ownership after deployments.
  2. Include parent-directory checks in permission troubleshooting.
  3. Audit mount source and target pairs after changes.
  4. Check filesystem type before resize commands.

Explanation

Correct Answer

A:

In this RHEL 10 system administration case: A service uses a bind-mounted directory with mismatched ownership after a deployment. Underlying reason: A bind mount exposes the source filesystem's permissions at another path. The most direct, approved resolution is: Compare the actual mounted source and service account IDs before correcting scoped ownership. Confirm it by checking: The service reads its data and other users retain limited access. Sustain the fix by: Test mount-source identity and ownership after deployments. 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

B:

Include parent-directory checks in permission troubleshooting. That is not sufficient for the reported RHEL task, because a bind mount exposes the source filesystem's permissions at another path.

C:

Audit mount source and target pairs after changes. That is not sufficient for the reported RHEL task, because a bind mount exposes the source filesystem's permissions at another path.

D:

Check filesystem type before resize commands. That is not sufficient for the reported RHEL task, because a bind mount exposes the source filesystem's permissions at another path.

Question 781

Original unofficial RHEL 10 RHCSA skill-check scenario: A backup restore replaces application directories with root-owned files and the application cannot write logs. Which action best addresses this situation?

  1. Inspect permissions on every parent using `namei -l` and correct the restricted path component.
  2. Restore approved ownership and targeted mode settings for the service-owned log path.
  3. Identify the unused approved block device and create XFS only on that device with `mkfs.xfs`.
  4. Extend the approved LV and grow ext4 using the appropriate supported filesystem resize operation.

Explanation

Correct Answer

B:

In this RHEL 10 system administration case: A backup restore replaces application directories with root-owned files and the application cannot write logs. Underlying reason: Restored metadata can differ from the service's required identity. The most direct, approved resolution is: Restore approved ownership and targeted mode settings for the service-owned log path. Confirm it by checking: The service can write logs while confidential files remain protected. Sustain the fix by: Compare metadata during restore drills. 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:

Inspect permissions on every parent using `namei -l` and correct the restricted path component. That is not sufficient for the reported RHEL task, because restored metadata can differ from the service's required identity.

Question 782

Original unofficial RHEL 10 RHCSA skill-check scenario: A backup restore replaces application directories with root-owned files and the application cannot write logs. Which observation best confirms the intended outcome?

  1. Authorized users traverse the path and open the intended file.
  2. The service can write logs while confidential files remain protected.
  3. `lsblk -f` reports XFS on the new LV and the root filesystem is unchanged.
  4. The ext4 mount shows increased capacity without loss of existing files.

Question 783

Original unofficial RHEL 10 RHCSA skill-check scenario: A backup restore replaces application directories with root-owned files and the application cannot write logs. Which system administration principle best explains this behavior?

  1. Directory search permission is required along every path component.
  2. Filesystem creation overwrites structures on the selected device.
  3. ext4 and XFS have different filesystem growth tools.
  4. Restored metadata can differ from the service's required identity.

Question 785

Original unofficial RHEL 10 RHCSA skill-check scenario: An administrator must run a one-time log rotation tonight but adds a daily cron job by mistake. Which action best addresses this situation?

  1. Use absolute paths and explicit environment assumptions in the scheduled command.
  2. Schedule the one-off command using `at` for the approved time and inspect the pending job list.
  3. Run `systemctl daemon-reload` and restart or reenable the timer as appropriate.
  4. Install the approved local RPM using DNF and verify its package registration and dependencies.

Explanation

Correct Answer

B:

In this RHEL 10 system administration case: An administrator must run a one-time log rotation tonight but adds a daily cron job by mistake. Underlying reason: `at` queues one-time tasks rather than repeating calendar schedules. The most direct, approved resolution is: Schedule the one-off command using `at` for the approved time and inspect the pending job list. Confirm it by checking: `atq` shows one scheduled execution and no daily recurrence. Sustain the fix by: Remove completed or obsolete one-time jobs from operational plans. 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;
