I got my CCNA back around 2002 and it expired in 2005 so it has been a good while since I took the exam. I can see that the style of the exam has changed, but I am not sure how much. Back then, there were quite a few questions based on memorizing the exact syntax of a command as opposed to principles and general knowledge. Is that still the case or has it changed? What I am getting at here, is that in order to prepare for the exam, do I need to put a lot of focus into memorizing the syntax of commands or will having a good overall understanding be good enough?
