I have Todd's CCENT book. Overall i think it is great. However i have been reading some comments from people who have recently taken the ICND1 and have had questions pertaining to Frame Relay. I am wondering: What exactly does Cisco expect you to know about Frame Relay for the ICND1? There really isn't much about it in Chapter 10, Introduction to Wide Area Networks. I was under the assumption that if I knew everything in Todd's book that I would be fully prepared for the ICND1.


Any help would be well appreciated as I'm writing my ICND1 in three days.
