Question 1150

Original unofficial RHEL 10 RHCSA skill-check scenario: A developer believes a correct username proves the process is allowed by SELinux to read any file that user owns. Which observation best confirms the intended outcome?

  1. The file and process types explain the access decision without changing broad Unix permissions.
  2. Context inspection reveals the mandatory-policy boundary even when UID matches.
  3. New payroll reports are not readable by unrelated local users.
  4. The intended file type survives relabel and reboot tests.

Explanation

Correct Answer

B:

In this RHEL 10 system administration case: A developer believes a correct username proves the process is allowed by SELinux to read any file that user owns. Underlying reason: SELinux decisions also depend on domain and object type, not just Unix ownership. The most direct, approved resolution is: Inspect the process's SELinux domain and the file's security type before attributing access. Confirm it by checking: Context inspection reveals the mandatory-policy boundary even when UID matches. Sustain the fix by: Validate service domains as well as user IDs. 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 file and process types explain the access decision without changing broad Unix permissions. That is not sufficient for the reported RHEL task, because SELinux decisions also depend on domain and object type, not just Unix ownership.

C:

New payroll reports are not readable by unrelated local users. That is not sufficient for the reported RHEL task, because SELinux decisions also depend on domain and object type, not just Unix ownership.

D:

The intended file type survives relabel and reboot tests. That is not sufficient for the reported RHEL task, because SELinux decisions also depend on domain and object type, not just Unix ownership.

Question 1151

Original unofficial RHEL 10 RHCSA skill-check scenario: A developer believes a correct username proves the process is allowed by SELinux to read any file that user owns. Which system administration principle best explains this behavior?

  1. SELinux mandatory access controls operate in addition to DAC permission bits.
  2. Umask removes permission bits from default creation modes.
  3. `chcon` does not establish a durable file-context policy rule.
  4. SELinux decisions also depend on domain and object type, not just Unix ownership.

Question 1152

Original unofficial RHEL 10 RHCSA skill-check scenario: A developer believes a correct username proves the process is allowed by SELinux to read any file that user owns. Which ongoing practice best prevents a recurrence?

  1. Validate service domains as well as user IDs.
  2. Include context checks in file access diagnostics.
  3. Test default modes for sensitive output paths.
  4. Prefer persistent mapping changes for required custom paths.

Question 1153

Original unofficial RHEL 10 RHCSA skill-check scenario: A web team moves content into `/var/www/html` but inherits a generic temporary-file context that causes a denial. Which action best addresses this situation?

  1. Define the intended persistent path-to-type mapping with `semanage fcontext`, then apply `restorecon`.
  2. Inspect `semanage port -l` and use the supported modify operation only if the approved policy permits reassignment.
  3. Use `restorecon` on the approved web directory when the default file-context policy applies.
  4. Inspect service process type and allowed port labeling with `semanage port -l`.

Explanation

Correct Answer

C:

In this RHEL 10 system administration case: A web team moves content into `/var/www/html` but inherits a generic temporary-file context that causes a denial. Underlying reason: Files relocated from unusual directories can retain labels inappropriate for their new purpose. The most direct, approved resolution is: Use `restorecon` on the approved web directory when the default file-context policy applies. Confirm it by checking: `ls -Z` shows the expected web-content type and HTTP access succeeds. Sustain the fix by: Verify SELinux labels after web deployments. 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:

Define the intended persistent path-to-type mapping with `semanage fcontext`, then apply `restorecon`. That is not sufficient for the reported RHEL task, because files relocated from unusual directories can retain labels inappropriate for their new purpose.

  2. The custom path retains the intended label after repeated restoration.
  3. The target port has one correct type and dependent services remain functional.
  4. The relevant service type and permitted port association are identified.

  1. Files relocated from unusual directories can retain labels inappropriate for their new purpose.
  2. `restorecon` applies defined policy mappings; it does not invent mappings for custom paths.
  3. A port/protocol binding cannot be arbitrarily duplicated across SELinux types.

  2. Audit existing port assignments before changing labels.
  3. Verify SELinux labels after web deployments.
  4. Check both controls during custom-port deployments.

Question 1157

Original unofficial RHEL 10 RHCSA skill-check scenario: A custom application stores approved web assets under `/srv/appcontent`, and `restorecon` resets labels to the wrong default type. Which action best addresses this situation?

  1. Replace the temporary label change with a supported persistent `semanage fcontext` policy and restore labels.
  2. Diagnose the denial and restore enforcing with a persistent approved SELinux configuration rather than leaving permissive troubleshooting state.
  3. Configure a restrictive umask for the process and verify the report file mode.
