When FortiGate performs SSL certificate inspection with default settings, it checks if the Server Name Indication (SNI) matches either the Common Name (CN) or any Subject Alternative Name (SAN) in the server certificate. If there is no match, FortiGate does not block the connection; instead, it uses the CN value from the certificate's subject field to continue web filtering and categorization.

This behavior is described in the official Fortinet 7.6.4 Administration Guide:

“Check the SNI in the hello message with the CN or SAN field in the returned server certificate: Enable: If it is mismatched, use the CN in the server certificate.” This is the default (Enable) mode, which differs from the Strict mode that would block the mismatched connection.

By default, this policy ensures service continuity and prevents disruptions due to certificate mismatches, allowing FortiGate to log and inspect based on the CN even when the requested SNI does not match. It provides a balance between connection reliability and the accuracy of filtering by certificate identity, allowing security policies to remain functional without unnecessary blocks. This approach is recommended by Fortinet to maintain usability for end-users while still supporting granular inspection.

The BGP debug output shows session information for peers, including state details. According to official Fortinet BGP documentation, if the session state with a peer does not show "Idle," "Active," or "Connect," but instead shows "Established," "Up," or related counters (e.g., messages sent/received or uptime), it indicates the session is operational. In this scenario, the peer 10.127.0.75 is the only one showing a positive indication of a live, established session. Other options like neighbor-range configuration, AS mismatch, or route-maps blocking prefixes are not supported by evidence provided in a simple BGP session state debug, nor does the output show errors relating to local or remote AS issues.

The correct interpretation comes from Fortinet's BGP troubleshooting guide, which outlines how to read session status and neighbor states in debug and summary outputs.

IKEv1 (Internet Key Exchange version 1) and IKEv2 are protocols used for establishing IPsec VPN tunnels, and both protocols share the conceptual division into two phases, as clearly described in Fortinet VPN documentation:

Phase 1 handles negotiation and establishment of a secure IKE Security Association (SA) between peers.

Phase 2 negotiates parameters for the IPsec Security Association, which secures actual data traffic between peers.

While IKEv2 streamlines and improves upon IKEv1 by merging some message exchanges and simplifying configuration, it maintains the same core two-phase concept: Phase 1 (IKE SA) and Phase 2 (IPsec SA). This is a foundational VPN concept referenced widely in both IKEv1 and IKEv2 literature.

Other statements are incorrect:

Asymmetric authentication is possible, but not mandatory for both.

Both protocols commonly use UDP port 500, sometimes 4500 for NAT traversal, but they are not designed to run on TCP.

The protocol feature compatibility over TCP/UDP is not correctly described in the other options.
