The correct answers are B and D .

The study guide explains that expectation sessions are pinhole sessions created by session helpers for protocols such as FTP that need additional negotiated connections. It states: “FortiGate created an expectation session and opened the pinhole port for the expected return traffic” and also shows that the firewall “creates an expected (pinhole) session to allow the traffic”

That makes D correct.

For B , the study guide explains the gwy= field in session output: the first value is the gateway to the destination , and the second is the gateway to the source

In the exhibit, the original-direction traffic is DNATed here:

hook=pre dir=org act=dnat 10.171.121.38:0- > 10.200.1.1:60426(10.0.1.10:50365)

So the destination after DNAT is the internal host 10.0.1.10, and the session’s first gwy value corresponds to the next hop toward that destination. That makes B correct.

Why the other options are wrong:

A is wrong because this is an expectation/session-helper behavior, not an IPS-engine-created session. The study guide ties expectation sessions to helpers such as FTP, not IPS.

C is wrong because 10.200.1.1 is the translated address used before DNAT, not the next hop used to forward the original-direction traffic after translation to the internal destination.

So the verified answers are: B, D .
