Answers
D.
This is a pinhole session created to allow traffic for a protocol that requires additional sessions to operate through FortiGate.
Suggested answer: B, D

Explanation:

Session Creation: The output shows an expected session, likely due to a pinhole, which is a dynamically created rule to allow specific traffic through the firewall.

Routing Decision:

The original direction of traffic comes from the IP address 10.171.121.38.

The next-hop IP address for this traffic is 10.0.1.10 as indicated by the routing decision in the output.

Pinhole Session: Pinhole sessions are typically created for protocols that require additional sessions (e.g., FTP, SIP) to function properly. This ensures the necessary traffic can pass through the firewall.

Debugging Commands: The diagnose sys session list command is used to list session information, which helps in understanding traffic flow and troubleshooting connectivity issues.
