The study guide explicitly states: “IKE version 2 does not interoperate with IKE version 1, but they share enough of the header format that both versions can unambiguously operate over the same UDP port.”
That directly proves B .
Why the other options are wrong:
A is wrong because the study guide shows authentication methods as Asymmetric for IKEv2 and Symmetric for IKEv1
C is wrong because the study guide does not say they use the same TCP port; instead, it specifically says they can operate over the same UDP port
D is wrong because the study guide states: “IKEv2 does not use the concept of phase 1 or phase 2” , even though FortiOS CLI/GUI still uses those terms for configuration purposes
