NSE 7 – Network Security Technologies 7.2 — Question 63

Which statement about IKEv2 is true?

Answer options

• A. Both IKEv1 and IKEv2 share the feature of asymmetric authentication.
• B. IKEv1 and IKEv2 have enough of the header format in common that both versions can run over the same UDP port.
• C. IKEv1 and IKEv2 use same TCP port but run on different UDP ports.
• D. IKEv1 and IKEv2 share the concept of phase1 and phase2.

Correct answer: B

Explanation

The correct answer is B because IKEv1 and IKEv2 indeed share a similar header format allowing them to utilize the same UDP port for communication. Option A is incorrect as IKEv2 introduces improvements in authentication methods. Option C is wrong because IKEv1 and IKEv2 do not share the same TCP port, and option D is misleading since while both versions have phases, their implementations differ significantly.
