AH is the correct answer, but IKE is super important too!

Wait, L2TP isn't even related to IPSec, right?

I’m leaning towards AH as the answer, but I feel like I should double-check if ESP has any authentication features too.

I keep mixing up IKE and AH; I know IKE is related to key exchange, but does it also play a role in authentication?

I remember practicing a question like this, and I think it was about how ESP provides confidentiality, not authentication.

I think the Authentication Header (AH) is the one that handles authentication in IPSec, but I'm not completely sure.

I'm a bit confused on this one. I know IPSec has a lot of moving parts, and I'm not entirely sure which element is responsible for authentication. I'll have to review my notes to refresh my memory.

The key here is understanding the different IPSec protocols. I think the Authentication Header (AH) is the right answer, as it's specifically designed for authentication in IPSec.

Hmm, I'm a bit unsure about this one. I know IPSec has different components, but I can't quite remember which one handles authentication. I'll have to think this through carefully.

Hmm, I'm a bit confused by the difference between V$SESSION_EVENT and V$SERVICE_EVENT. I'll need to review my notes on those views to make sure I understand them properly.

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.
