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

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

EIGRP? Not really relevant for this issue.

I think CHAP is also a good option here.

IPSec is definitely a solid choice for preventing replay attacks.

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.

Direct evidence is definitely the way to go. It's the most straightforward and credible type, so that's the one I'll be selecting.

I'm a bit unsure about this one. I'll need to re-read the question and think through the different participant needs more carefully.

I think the statement about location D having the strongest RF signal strength might be correct, but I'm not entirely sure how to interpret the dB values accurately.

I'm pretty confident I know the answer to this one. The question is asking about products supported as "Extended" in DNA-C 1.1, so I'll focus on that.

EIGRP? Really? I'd rather have my passwords stolen than use that protocol to protect against replay attacks.

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.

This is a pretty straightforward question. The correct answers are obvious - IPSec, L2TP, and CHAP. Anything else is just a distraction.

I'm not sure why EIGRP, PAP, SNMP, and IGRP are even listed as options. Those are clearly not designed to mitigate replay attacks on VPNs.

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.
