The problem I have with this question is the requirement that you need to provide ONE telnet line only, and the password needs to be encrypted. My understanding of the way telnet works is that you do not get to choose which of the vty lines you log in on; they are assigned one at a time until they are all filled up. So if the vty 0 line is not setup for access, and noone is on it, then you won't be able to log in to the router because vty 1 would only be made available if someone was on vty 0. The answer as stated would not create a workable solution, but is the only answer that would meet both requirements of the question.
