Helped sort my problem out. I did CCNA back in school, but my teacher had not passed the final and he gave us all the answers for all the exams. So I don't know as much as I should do :).

As for LMI keepalive if the exam question asks you to disable it, disable it. If they don't say anything about it, don't touch it ;) Some versions you can remove them by stopping and starting Frame Relay (no encap, encap).

int se 1/0
sh
no encaps
encaps frame-relay
no keepalive
no shut

now since router will not run keepalives it will not run any dlci and so mappings arent there ;-)
