Question 80
After a corrective change at a corporate headquarters, the team documents: A helpdesk sees User-ID denied sessions and assumes the Security rule is absent, but the firewall reports no identity mapping for the authenticated user. Which repeatable control BEST prevents a recurrence?
Explanation
Correct Answer
Include identity mapping health in application access triage. This control reduces recurrence of the documented mechanism: A Security rule can exist yet fail when required User-ID metadata is unavailable. It creates a repeatable check around the needed response: Repair identity mapping integration and validate group-to-user association at the target device.
Incorrect Answers
Compare effective local values with the central baseline after each emergency fix. That safeguard addresses another potential failure: An administrator edits a firewall's DNS setting directly on the device, but the next SCM push restores the old value and name resolution fails again. It is not the most targeted recurring control for the described cause: A Security rule can exist yet fail when required User-ID metadata is unavailable.
Include NAT, route and Security zone correlation in inbound troubleshooting. That safeguard addresses another potential failure: An analyst sees a traffic denial for an internal web server but its destination NAT is correct; route lookup selects the wrong destination zone due to an old route. It is not the most targeted recurring control for the described cause: A Security rule can exist yet fail when required User-ID metadata is unavailable.
Audit conflicting inherited and local snippet objects before pushing. That safeguard addresses another potential failure: A regional team updates a shared snippet but its higher-priority local snippet continues overriding the same object on one site. It is not the most targeted recurring control for the described cause: A Security rule can exist yet fail when required User-ID metadata is unavailable.
