Question 240
After a corrective change at a national SOC, the team documents: A newly configured address object is referenced by a rule but the selected target device rejects the policy because another inherited object uses a conflicting name. Which repeatable control BEST prevents a recurrence?
Explanation
Correct Answer
Enforce namespace and object ownership conventions across folders. This control reduces recurrence of the documented mechanism: Same-name object collisions can invalidate or override effective configuration. It creates a repeatable check around the needed response: Resolve object naming and inherited configuration conflicts in the correct scope.
Incorrect Answers
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: Same-name object collisions can invalidate or override effective configuration.
Review interface-to-router and route dependencies with network changes. That safeguard addresses another potential failure: Traffic stops after an interface is moved into a different virtual router but the team edits NAT before checking the new route table. It is not the most targeted recurring control for the described cause: Same-name object collisions can invalidate or override effective configuration.
Monitor NTP reachability and time offset on managed firewalls. That safeguard addresses another potential failure: A managed firewall displays the wrong time and rejects certificate-based cloud connections after its NTP service becomes unavailable. It is not the most targeted recurring control for the described cause: Same-name object collisions can invalidate or override effective configuration.
