C is not related at all. It’s about VoIP, not IPsec.

D is definitely one of the IPsec protocols. I remember learning about Authentication Header in my networking class.

Skinny Client Control Protocol? Really? That's not even close to being an IPsec protocol. Whoever came up with that option must have been having a bad day.

I'm pretty sure C is also an option, but I could be wrong. Better double-check that.

A and B are the correct answers. IPsec uses Encapsulating Security Payload and Internet Key Exchange protocols.

I’m pretty sure that A and D are the main protocols used in IPsec, but I can't recall if B is also correct.

Hmm, I'm a bit unsure about this one. I know IPsec has some core protocols, but I can't quite recall all the details. I'll go with A and B since those sound familiar, but I'll have to leave C and D as guesses.

Ah, this is a good IPsec question. I'm confident A, B, and D are the right answers since those are the main IPsec protocols we covered. Not sure about C, so I'll leave that one unchecked.

I remember learning about IPsec in class, and I'm pretty sure A, B, and D are the correct protocols it uses. C seems out of place, so I'll skip that one.

I think Encapsulating Security Payload and Authentication Header are definitely part of IPsec, but I need to double-check if Internet Key Exchange is also included.

Okay, I know IPsec uses encryption and authentication, so A and D sound like the right answers. But I'm not familiar with B and C, so I'll have to guess on those.
