I'm not sure, but I think both A) and D) are correct. They both play a role in authentication and security for IPSec.

I disagree, I believe the correct answer is D) Encapsulating Security Payload (ESP). It also provides authentication and encryption for IPSec.

I'm going to go with B) Layer 2 Tunneling Protocol (L2TP) because it sounds the most fun to say. Authentication? Who needs that when you've got L2TP?

C) Internet Key Exchange (IKE) is used for key management in IPSec, not authentication. I think the authors of this exam question are trying to trick us!

Haha, B) Layer 2 Tunneling Protocol (L2TP)? Really? That's not even in the same league as IPSec. I'm going with A) for sure.

I was about to choose D) Encapsulating Security Payload (ESP), but then I remembered that's for encryption, not authentication. Good thing I double-checked!
