just finished the networking academy, & will be taking the old CCNA 640-801. We didn't cover ISDN in detail b/c it is being phased out. The instructor thought the exam would not have ISDN related questions, however all of the study guide I am using talk about ISDN. Do you think I need to learn all of it for the exam? or do you think the latest versions of 640-801 donh't really ask about ISDN? Anyone recently taken 640-801 and did you ahve questions on ISDN?
Thanks!!!
Thanks!!!
