TRAFFIC-FILTER is for data traffic that goes through the router. ACCESS-CLASS is used for IPv6 line vty ACL. (MGMT traffic for IPv6) So clearly it will not be a traffic filter but an access filter.

I did not see the image clearly, it has to be C but wouldn’t the message say “refused by host”?

The exhibit on the right is show ping is working and the user is using telnet to connect sourcing the loopback interface.

Its a fifty fifty chance between B and C. For one I would lean towards B without knowing what the hell is going, for a couple of reasons: A trsnport input SCP is a file transfer protocol C Telnet is least secure and hopefully is not used in production D Transport input none would prevent remote access.

WHERE IS THE ACL?

We don't see that in the configuration. But through process of elimination, we can see that A & D are wrong because "transport input ssh telnet" already allows remote access. So we are just left with two answers. From the image we can see the user is using "telnet" to remote access, so we must choose C. Although we cannot see an ACL, we can see all configuration looks correct and the connection is failing. So the answer is "C"
