Question 770

Original unofficial RHEL 10 RHCSA skill-check scenario: A developer can read an ext4 file but cannot change it despite being the file owner because the filesystem is mounted read-only. Which observation best confirms the intended outcome?

  1. Authorized users traverse the path and open the intended file.
  2. `df -h` reports the intended larger filesystem and original files remain.
  3. Mount succeeds when the server export is available and authorized.
  4. The filesystem is writable after safe remediation and file mode remains appropriate.

Explanation

Correct Answer

D:

In this RHEL 10 system administration case: A developer can read an ext4 file but cannot change it despite being the file owner because the filesystem is mounted read-only. Underlying reason: Mount flags can override otherwise sufficient file permissions. The most direct, approved resolution is: Inspect mount state and fix the approved filesystem-level condition rather than using chmod. Confirm it by checking: The filesystem is writable after safe remediation and file mode remains appropriate. Sustain the fix by: Check mount options before changing ownership. 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:

Authorized users traverse the path and open the intended file. That is not sufficient for the reported RHEL task, because mount flags can override otherwise sufficient file permissions.

B:

`df -h` reports the intended larger filesystem and original files remain. That is not sufficient for the reported RHEL task, because mount flags can override otherwise sufficient file permissions.

C:

Mount succeeds when the server export is available and authorized. That is not sufficient for the reported RHEL task, because mount flags can override otherwise sufficient file permissions.

Question 771

Original unofficial RHEL 10 RHCSA skill-check scenario: A developer can read an ext4 file but cannot change it despite being the file owner because the filesystem is mounted read-only. Which system administration principle best explains this behavior?

  1. Directory search permission is required along every path component.
  2. Expanding a block LV does not automatically expand its filesystem.
  3. Mount flags can override otherwise sufficient file permissions.
  4. NFS depends on network service and remote export policy.

Question 772

Original unofficial RHEL 10 RHCSA skill-check scenario: A developer can read an ext4 file but cannot change it despite being the file owner because the filesystem is mounted read-only. Which ongoing practice best prevents a recurrence?

  1. Include parent-directory checks in permission troubleshooting.
  2. Check mount options before changing ownership.
  3. Verify both LV and filesystem sizes after storage growth.
  4. Monitor server availability and client mount failures.

Question 773

Original unofficial RHEL 10 RHCSA skill-check scenario: An application creates files with a restrictive default umask and collaborators cannot read new shared data. Which action best addresses this situation?

  1. Inspect mount state and fix the approved filesystem-level condition rather than using chmod.
  2. Configure an approved umask or collaboration directory permissions without opening access globally.
  3. Check export controls and consistent identity mappings before changing file modes broadly.
  4. Avoid unsupported XFS shrinking and select an approved migration or new-volume design.

Explanation

Correct Answer

B:

In this RHEL 10 system administration case: An application creates files with a restrictive default umask and collaborators cannot read new shared data. Underlying reason: Initial permission bits are modified by the process's umask. The most direct, approved resolution is: Configure an approved umask or collaboration directory permissions without opening access globally. Confirm it by checking: Newly created files have expected effective group access. Sustain the fix by: Verify default creation modes during service onboarding.

Original unofficial RHEL 10 RHCSA skill-check scenario: An application creates files with a restrictive default umask and collaborators cannot read new shared data. Which observation best confirms the intended outcome?

  1. The filesystem is writable after safe remediation and file mode remains appropriate.
  2. The authorized identity can access the export while unauthorized access is blocked.
  3. Newly created files have expected effective group access.
  4. The original XFS data remains intact and the replacement capacity plan is documented.

Question 777

Original unofficial RHEL 10 RHCSA skill-check scenario: A service uses a bind-mounted directory with mismatched ownership after a deployment. Which action best addresses this situation?

  1. Inspect permissions on every parent using `namei -l` and correct the restricted path component.
  2. Compare the actual mounted source and service account IDs before correcting scoped ownership.
  3. Unmount safely and remount the verified device at the approved target path.
  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 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.

  1. Authorized users traverse the path and open the intended file.
  2. `findmnt` reports the intended source-to-target mapping and the app reads the right files.
  3. The service reads its data and other users retain limited access.
  4. The ext4 mount shows increased capacity without loss of existing files.
