In this RHEL 10 system administration case: A custom application stores approved web assets under `/srv/appcontent`, and `restorecon` resets labels to the wrong default type. Underlying reason: `restorecon` applies defined policy mappings; it does not invent mappings for custom paths. The most direct, approved resolution is: Define the intended persistent path-to-type mapping with `semanage fcontext`, then apply `restorecon`. Confirm it by checking: The custom path retains the intended label after repeated restoration. Sustain the fix by: Record permanent fcontext rules for nonstandard paths. This is the INTENDED response for the best ongoing operational safeguard. It is a knowledge-check explanation, not a verified hands-on Red Hat exam answer;

In this RHEL 10 system administration case: A technician fixes an AVC using `chcon` but the label reverts after a full relabel. Underlying reason: `chcon` does not establish a durable file-context policy rule. The most direct, approved resolution is: Replace the temporary label change with a supported persistent `semanage fcontext` policy and restore labels. Confirm it by checking: The intended file type survives relabel and reboot tests. Sustain the fix by: Prefer persistent mapping changes for required custom paths. 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;

In this RHEL 10 system administration case: A directory has the correct SELinux label but files nested beneath it retain old types after migration. Underlying reason: Labels are stored per inode and do not automatically conform merely because a parent label changed. The most direct, approved resolution is: Apply the approved recursive context restoration to the intended subtree after checking scope. Confirm it by checking: Files and subdirectories show consistent permitted context types. Sustain the fix by: Verify representative nested labels after data moves.

In this RHEL 10 system administration case: A custom HTTP service starts on port 8088 but SELinux prevents it from binding even though firewalld permits the port. Underlying reason: SELinux checks process-to-port permissions independently of firewall routing. The most direct, approved resolution is: Add the approved TCP port to the appropriate SELinux HTTP port type using `semanage port` after checking existing entries. Confirm it by checking: The daemon binds successfully and the port appears under the intended SELinux type. Sustain the fix by: Review port type labels whenever changing service listeners.
