Question 1190

Original unofficial RHEL 10 RHCSA skill-check scenario: An operator sets a Boolean with a runtime-only command but the application's access fails again after reboot. Which observation best confirms the intended outcome?

  1. The target service works with no unrelated Boolean policy expansion.
  2. Management access works only through authorized interfaces.
  3. `getsebool` or `semanage boolean -l` shows the intended state after restart.
  4. Network access and daemon binding succeed under separate approved policies.

Explanation

Correct Answer

C:

In this RHEL 10 system administration case: An operator sets a Boolean with a runtime-only command but the application's access fails again after reboot. Underlying reason: Runtime Boolean toggles may not persist across system restart without explicit policy storage. The most direct, approved resolution is: Set the approved Boolean persistently using the supported persistent option and verify its policy state. Confirm it by checking: `getsebool` or `semanage boolean -l` shows the intended state after restart. Sustain the fix by: Include reboot checks in SELinux change verification. 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:

The target service works with no unrelated Boolean policy expansion. That is not sufficient for the reported RHEL task, because runtime Boolean toggles may not persist across system restart without explicit policy storage.

B:

Management access works only through authorized interfaces. That is not sufficient for the reported RHEL task, because runtime Boolean toggles may not persist across system restart without explicit policy storage.

D:

Network access and daemon binding succeed under separate approved policies. That is not sufficient for the reported RHEL task, because runtime Boolean toggles may not persist across system restart without explicit policy storage.

Question 1191

Original unofficial RHEL 10 RHCSA skill-check scenario: An operator sets a Boolean with a runtime-only command but the application's access fails again after reboot. Which system administration principle best explains this behavior?

  1. Runtime Boolean toggles may not persist across system restart without explicit policy storage.
  2. Each Boolean controls a particular optional rule set rather than granting universal access.
  3. Zone placement determines where a firewalld service exception applies.
  4. Firewall policies and SELinux port controls govern different layers.

  3. Audit interface-to-zone assignments during network changes.
  4. Use two-control acceptance tests for custom services.

Question 1193

Original unofficial RHEL 10 RHCSA skill-check scenario: A security engineer enables several permissive SELinux Booleans without establishing which one addresses an AVC. Which action best addresses this situation?

  1. Set the approved Boolean persistently using the supported persistent option and verify its policy state.
  2. Review the custom association and remove only the obsolete approved entry if no services depend on it.
  3. Inspect AVC evidence and supported policy descriptions before changing only the required Boolean.

Question 1197

Original unofficial RHEL 10 RHCSA skill-check scenario: An application team tries to solve an incorrect file-context label by enabling an unrelated network-access Boolean. Which action best addresses this situation?

  1. Inspect the applicable Boolean and enable it persistently only when justified by the service's intended access.
  2. Fix the actual mislabeled file or appropriate policy rule, leaving unrelated Booleans unchanged.
  3. Add the approved TCP port to the appropriate SELinux HTTP port type using `semanage port` after checking existing entries.
  4. Configure a restrictive umask for the process and verify the report file mode.

Explanation

Correct Answer

B:

In this RHEL 10 system administration case: An application team tries to solve an incorrect file-context label by enabling an unrelated network-access Boolean. Underlying reason: Label mismatch and Boolean-controlled exceptions are distinct SELinux failure causes.
