Question 690

Original unofficial RHEL 10 RHCSA skill-check scenario: A filesystem refuses to unmount because a shell process has its current directory inside the mount. Which observation best confirms the intended outcome?

  1. The filesystem unmounts cleanly and no open files remain.
  2. `findmnt` reports the intended source-to-target mapping and the app reads the right files.
  3. The mount appears on access and may unmount after the configured idle period.
  4. The original XFS data remains intact and the replacement capacity plan is documented.

Explanation

Correct Answer

A:

In this RHEL 10 system administration case: A filesystem refuses to unmount because a shell process has its current directory inside the mount. Underlying reason: Active file references can prevent safe unmount. The most direct, approved resolution is: Identify users of the mount with supported diagnostics and exit or stop those consumers before unmounting. Confirm it by checking: The filesystem unmounts cleanly and no open files remain. Sustain the fix by: Plan service quiescence during filesystem maintenance. 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

B:

`findmnt` reports the intended source-to-target mapping and the app reads the right files. That is not sufficient for the reported RHEL task, because active file references can prevent safe unmount.

C:

The mount appears on access and may unmount after the configured idle period. That is not sufficient for the reported RHEL task, because active file references can prevent safe unmount.

D:

The original XFS data remains intact and the replacement capacity plan is documented. That is not sufficient for the reported RHEL task, because active file references can prevent safe unmount.

Question 691

Original unofficial RHEL 10 RHCSA skill-check scenario: A filesystem refuses to unmount because a shell process has its current directory inside the mount. Which system administration principle best explains this behavior?

  1. Mounting changes the visible filesystem tree at the selected directory.
  2. Autofs intentionally manages mount lifecycles based on demand.
  3. XFS supports online growth but not shrinking through the standard filesystem tools.
  4. Active file references can prevent safe unmount.

Question 692

Original unofficial RHEL 10 RHCSA skill-check scenario: A filesystem refuses to unmount because a shell process has its current directory inside the mount. Which ongoing practice best prevents a recurrence?

  1. Audit mount source and target pairs after changes.
  2. Set workload-compatible timeouts and test after inactivity.
  3. Plan service quiescence during filesystem maintenance.
  4. Verify filesystem type before planning size reductions.

Question 693

Original unofficial RHEL 10 RHCSA skill-check scenario: A team mounts a block device to the wrong directory and an application begins reading unexpected content. Which action best addresses this situation?

  1. Mount the verified archive volume first and confirm with `findmnt /archive` before writing.
  2. Extend the approved LV and grow ext4 using the appropriate supported filesystem resize operation.
  3. Unmount safely and remount the verified device at the approved target path.
  4. Inspect mount state and fix the approved filesystem-level condition rather than using chmod.

Question 694

Original unofficial RHEL 10 RHCSA skill-check scenario: A team mounts a block device to the wrong directory and an application begins reading unexpected content. Which observation best confirms the intended outcome?

  1. Reports are stored on the intended dedicated volume rather than root.
  2. The ext4 mount shows increased capacity without loss of existing files.
  3. The filesystem is writable after safe remediation and file mode remains appropriate.
  4. `findmnt` reports the intended source-to-target mapping and the app reads the right files.

Question 695

Original unofficial RHEL 10 RHCSA skill-check scenario: A team mounts a block device to the wrong directory and an application begins reading unexpected content. Which system administration principle best explains this behavior?

  1. A mountpoint directory exists independently of whether a filesystem is mounted there.

  3. Mount flags can override otherwise sufficient file permissions.
  4. Mounting changes the visible filesystem tree at the selected directory.

Question 697

Original unofficial RHEL 10 RHCSA skill-check scenario: A user manually mounts an external test filesystem successfully but expects it to remain mounted after reboot. Which action best addresses this situation?

  1. Mount the verified archive volume first and confirm with `findmnt /archive` before writing.
  2. Add a correct approved fstab entry or documented supported automount policy when persistence is required.
  3. Extend the approved LV and grow ext4 using the appropriate supported filesystem resize operation.
  4. Check export controls and consistent identity mappings before changing file modes broadly.

Explanation

Correct Answer

B:

In this RHEL 10 system administration case: A user manually mounts an external test filesystem successfully but expects it to remain mounted after reboot. Underlying reason: Runtime mount commands do not create boot-time configuration. The most direct, approved resolution is: Add a correct approved fstab entry or documented supported automount policy when persistence is required.
