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.
