Question 110
During follow-up testing at a hospital campus, the original fault was: An analyst troubleshoots denied traffic by checking only the application port but ignores that the destination zone changed due to a tunnel migration. Which measured result demonstrates recovery rather than an unrelated improvement?
Explanation
Correct Answer
The migrated application matches the intended zone rule without a broad any-zone exception. This evidence directly tests the intended corrective action: Review route selection and effective source/destination zones, then correct the Security rule if needed. It confirms the failure mechanism—Security policy uses actual zone classification; port alone cannot explain rule matching.—has been addressed in the actual affected flow.
Incorrect Answers
The target validates the resulting single intended definition and the policy matches test sessions. This would verify resolution of a different case: 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. It does not show that the reported issue was fixed or that its intended action—Review route selection and effective source/destination zones, then correct the Security rule if needed.—worked.
Inbound test sessions reach the correct server without adding any-zone broad allows. This would verify resolution of a different case: 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 does not show that the reported issue was fixed or that its intended action—Review route selection and effective source/destination zones, then correct the Security rule if needed.—worked.
After a push and reboot test the firewall resolves management hosts with the approved DNS servers. This would verify resolution of a different case: 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 does not show that the reported issue was fixed or that its intended action—Review route selection and effective source/destination zones, then correct the Security rule if needed.—worked.
