Question #3
Which statement about IKEv2 is true?
Correct answer: B
Explanation
IKEv2 keeps a header format close enough to IKEv1 that both versions run on the same UDP port 500 and can be distinguished by the version field. Asymmetric authentication and the phase 1/phase 2 naming are not shared with IKEv1.
Question #4
Which exchange lakes care of DoS protection in IKEv2?
Correct answer: D
Explanation
The IKE_SA_INIT exchange is where the responder can return a COOKIE notification forcing the initiator to prove source address validity, which is IKEv2's DoS protection. IKE_Auth and CREATE_CHILD_SA happen after the IKE SA exists and offer no such protection.
