L2TP could work too, but it needs IPSec for better security.

Surprised that PAP is even listed, it’s not secure at all!

I practiced a similar question where IPSec was definitely one of the correct answers, but I’m a bit confused about L2TP and its security features.

CHAP seems like a good choice too since it uses a challenge-response mechanism, which should help prevent replay attacks.

I’m not too sure about PAP; I think it’s not secure enough against replay attacks, but I can't recall the details.

I remember that IPSec is often mentioned as a strong option for securing VPNs, so I think that might be one of the answers.

I'm going with IPSec, L2TP, and CHAP. If that doesn't work, I'll just tell the examiner that my dog must have stepped on the keyboard when I was taking the test.

I hope the real exam doesn't have trick questions like this. It's like they're trying to see if we'll just randomly select three options without thinking it through.

IPSec, L2TP, and CHAP seem like the most relevant options here to prevent replay attacks. IPSec provides strong encryption and authentication, L2TP creates a secure tunnel, and CHAP adds an extra layer of challenge-response authentication.
