Question 810
An operations review at a service-provider edge has corrected: A proprietary payroll client is classified unknown-tcp and analysts propose an application override before documenting what the protocol actually does. Which observation specifically confirms success?
Explanation
Correct Answer
Approved payroll sessions classify correctly while threat inspection remains active where supported. This evidence directly tests the intended corrective action: Prefer a verified custom App-ID signature or supported application identification where practical; scope override only if justified. It confirms the failure mechanism—Application override can reduce normal layer-7 inspection and is not a harmless naming change.—has been addressed in the actual affected flow.
Incorrect Answers
The current service is natively classified and receives the expected threat inspection. This would verify resolution of a different case: After a legacy protocol is replaced, its application override remains above normal classification rules for the same destination. It does not show that the reported issue was fixed or that its intended action—Prefer a verified custom App-ID signature or supported application identification where practical; scope override only if justified.—worked.
Only the legacy app receives override classification; normal web traffic retains native App-ID. This would verify resolution of a different case: An application override rule matches all TCP traffic to a shared server rather than only a legacy protocol port, hiding unrelated web applications from normal App-ID. It does not show that the reported issue was fixed or that its intended action—Prefer a verified custom App-ID signature or supported application identification where practical; scope override only if justified.—worked.
The SaaS app is correctly recognized and eligible security profiles apply again. This would verify resolution of a different case: An engineer deploys an override for a common SaaS app to force a custom name, then finds URL filtering and threat events no longer correspond to the native application. It does not show that the reported issue was fixed or that its intended action—Prefer a verified custom App-ID signature or supported application identification where practical; scope override only if justified.—worked.
