Question 1130

Original unofficial RHEL 10 RHCSA skill-check scenario: A deployment fails with an SELinux AVC and the team decides to disable SELinux system-wide. Which observation best confirms the intended outcome?

  1. `getenforce` reports Enforcing after restart and the service functions with corrected policy.
  2. The policy no longer includes the retired custom port while active services retain access.
  3. The service works and `getenforce` still reports Enforcing.
  4. Files created by the service show the required mode after restart.

Explanation

Correct Answer

C:

In this RHEL 10 system administration case: A deployment fails with an SELinux AVC and the team decides to disable SELinux system-wide. Underlying reason: SELinux denials are often addressable by appropriate policy configuration rather than disabling enforcement. The most direct, approved resolution is: Inspect the denial and correct its supported labeling or Boolean cause while keeping enforcing mode. Confirm it by checking: The service works and `getenforce` still reports Enforcing. Sustain the fix by: Require AVC analysis before policy exceptions. 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:

`getenforce` reports Enforcing after restart and the service functions with corrected policy. That is not sufficient for the reported RHEL task, because SELinux denials are often addressable by appropriate policy configuration rather than disabling enforcement.

B:

The policy no longer includes the retired custom port while active services retain access. That is not sufficient for the reported RHEL task, because SELinux denials are often addressable by appropriate policy configuration rather than disabling enforcement.

D:

Files created by the service show the required mode after restart. That is not sufficient for the reported RHEL task, because SELinux denials are often addressable by appropriate policy configuration rather than disabling enforcement.

Question 1131

Original unofficial RHEL 10 RHCSA skill-check scenario: A deployment fails with an SELinux AVC and the team decides to disable SELinux system-wide. Which system administration principle best explains this behavior?

  1. SELinux denials are often addressable by appropriate policy configuration rather than disabling enforcement.
  2. Runtime SELinux mode and persisted config are separate settings.
  3. Custom SELinux port mappings can outlive the application that required them.
  4. Service processes do not necessarily inherit settings from a user's interactive shell.

Question 1132

Original unofficial RHEL 10 RHCSA skill-check scenario: A deployment fails with an SELinux AVC and the team decides to disable SELinux system-wide. Which ongoing practice best prevents a recurrence?

  1. Require AVC analysis before policy exceptions.
  2. Audit persistent enforcing status after emergency troubleshooting.
  3. Reconcile custom port policy during service retirement.
  4. Test permission defaults in each execution context.

Question 1133

Original unofficial RHEL 10 RHCSA skill-check scenario: An engineer expects SELinux permissive mode to block disallowed access exactly like enforcing mode. Which action best addresses this situation?

  1. Use permissive only for approved diagnosis and test enforcement behavior in enforcing mode afterward.
  2. Diagnose the denial and restore enforcing with a persistent approved SELinux configuration rather than leaving permissive troubleshooting state.
  3. Review the custom association and remove only the obsolete approved entry if no services depend on it.
  4. Identify zone membership and restrict SSH to the approved management zone or source policy.

Explanation

Correct Answer

A:

In this RHEL 10 system administration case: An engineer expects SELinux permissive mode to block disallowed access exactly like enforcing mode. Underlying reason: Permissive logs denials but does not enforce them as enforcing mode does. The most direct, approved resolution is: Use permissive only for approved diagnosis and test enforcement behavior in enforcing mode afterward. Confirm it by checking: Audit events are captured during diagnosis and the final production test enforces policy. Sustain the fix by: Document temporary permissive sessions and their closure. 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;

Question 1137

Original unofficial RHEL 10 RHCSA skill-check scenario: A service cannot open a document even though Unix permissions allow it, and an operator checks only chmod. Which action best addresses this situation?

  1. Inspect service process type and allowed port labeling with `semanage port -l`.
  2. Replace the temporary label change with a supported persistent `semanage fcontext` policy and restore labels.
  3. Apply the approved recursive context restoration to the intended subtree after checking scope.
  4. Inspect SELinux contexts using `ls -Z`, process labeling, and relevant AVC messages.

Explanation

Correct Answer

D:

In this RHEL 10 system administration case: A service cannot open a document even though Unix permissions allow it, and an operator checks only chmod. Underlying reason: SELinux mandatory access controls operate in addition to DAC permission bits. The most direct, approved resolution is: Inspect SELinux contexts using `ls -Z`, process labeling, and relevant AVC messages. Confirm it by checking: The file and process types explain the access decision without changing broad Unix permissions. Sustain the fix by: Include context checks in file access diagnostics. 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;

A:

Inspect service process type and allowed port labeling with `semanage port -l`. That is not sufficient for the reported RHEL task, because SELinux mandatory access controls operate in addition to DAC permission bits.

Question 1138

Original unofficial RHEL 10 RHCSA skill-check scenario: A service cannot open a document even though Unix permissions allow it, and an operator checks only chmod. Which observation best confirms the intended outcome?

  1. The relevant service type and permitted port association are identified.
  2. The intended file type survives relabel and reboot tests.
  3. Files and subdirectories show consistent permitted context types.
  4. The file and process types explain the access decision without changing broad Unix permissions.

Question 1139

Original unofficial RHEL 10 RHCSA skill-check scenario: A service cannot open a document even though Unix permissions allow it, and an operator checks only chmod. Which system administration principle best explains this behavior?

  1. SELinux port type enforcement and firewall port access are distinct.
  2. `chcon` does not establish a durable file-context policy rule.
  3. SELinux mandatory access controls operate in addition to DAC permission bits.
  4. Labels are stored per inode and do not automatically conform merely because a parent label changed.
