Question 560
An EMS audit must validate correction of the following defect: A TLS inspection rule fails because the ZTNA access proxy presents an unexpected certificate. Which evidence is most decisive?
Explanation
Correct Answer
The appropriate test proves: The approved hostname establishes a validated encrypted session and enforces the correct access rule. A supporting corrective measure is to validate application-proxy TLS certificate chain and FQDN identity without disabling verification. This matters because ZTNA access still requires trusted transport endpoint identity and compatible certificate configuration.
Incorrect Answers
The alternate choice relates to 'A ZTNA client cannot connect because it does not have the required endpoint certificate after enrollment.' It would prompt verify supported EMS ZTNA certificate provisioning and FortiClient enrollment status. The current issue instead requires validate application-proxy TLS certificate chain and FQDN identity without disabling verification.
That option would be better suited to the separate incident 'A user can access public sites but the managed ZTNA application is absent from the local client configuration.' Its supporting principle is endpoint ZTNA client behavior depends on receiving the intended managed destination configuration. In this case the key condition is ZTNA access still requires trusted transport endpoint identity and compatible certificate configuration.
Although this option is relevant to 'A gateway ZTNA access event allows a request but the backend host is unreachable over its internal route.', it would not distinguish the actual incident described. The target is to validate application-proxy TLS certificate chain and FQDN identity without disabling verification. and establish the approved hostname establishes a validated encrypted session and enforces the correct access rule.
