Question 320
A FortiOS 7.6 team examines: A helpdesk needs to distinguish an unauthenticated client from one denied by its assigned group policy. Select TWO complementary choices: the most appropriate corrective action AND the specific evidence confirming success.
Explanation
Correct Answers
For the observed situation (A helpdesk needs to distinguish an unauthenticated client from one denied by its assigned group policy), the most specific acceptance evidence is: An authorized user appears with the correct mapped identity and a revoked user loses the protected resource after policy enforcement. It validates the recommended response: Inspect FortiGate authenticated user state and timeouts and revoke stale authorized sessions when access changes require it. This addresses the documented risk: Removed group membership may not immediately terminate an already established authenticated session without lifecycle controls.
The reported FortiOS 7.6 condition is: A helpdesk needs to distinguish an unauthenticated client from one denied by its assigned group policy. The targeted administrative response is: Inspect FortiGate authenticated user state and timeouts and revoke stale authorized sessions when access changes require it. The relevant failure risk is: Removed group membership may not immediately terminate an already established authenticated session without lifecycle controls. Validate with: An authorized user appears with the correct mapped identity and a revoked user loses the protected resource after policy enforcement.

Virtual IP destination nat for inbound services (2.2) addresses another technical failure: A configured VIP without a matching permit or correct port mapping does not make the backend reachable securely. The case states: the most appropriate corrective action AND the specific evidence confirming success. The most direct paired action and test is: An authorized user appears with the correct mapped identity and a revoked user loses the protected resource after policy enforcement.
Security profiles attached to permitted policies (2.1) would demonstrate or implement: Creating a web-filter or IPS profile alone offers no protection when the matched allow policy does not apply it. This case instead tests Authentication session visibility and revocation; the choice measures or changes another part of the system.
Domain controller event collection for fsso (2.4) would demonstrate or implement: A controlled domain sign-in produces an appropriate collector event and current user mapping at the firewall. The paired-answer requirement concerns Authentication session visibility and revocation; this alternative does not provide the matching intervention and separate acceptance evidence.
