I am gearing up for CCNA, I am wondering what is the most important part of it (Not just passing the test, but, Actually Knowing it). I know that the OSI layers have alot to do with the basics. I have that down (for the most part

) . I have access to routers and switches at work, so I guess that I'm lucky in that sense. I am just looking for the best way to proceed.
