Option C looks correct. Only 192.168.1.1 and 192.168.2.2 can access Telnet.

I keep mixing up the order of deny and permit statements; I hope I remember that the permits should come before the denies for the ACL to work correctly.

I feel like option A is wrong because it denies all Telnet traffic first, which doesn't match the goal of allowing those two specific IPs.

I'm not entirely sure, but I remember a practice question where we had to deny access first and then permit specific hosts. That might be relevant here.

I think the answer might be C because it allows both specific hosts and denies all others, which seems to fit the requirement.
