I definitely agree that there’s no way you could replace the main books or manuals completely but moreso that they would act as a supplement. E.G. you could have audio notes on topics such as: the deftault distances of EIGRP or RIP etc, The differences and key attributes of each routing protocol etc, the key features of switches and routers etc…that’s just to suggest but a few but like I said I feel this idea has got unlimited potential.

Thanks for your feedback and comments!

When it comes to explaining store-and-forward, and describing the internals of a packet, I think that diagrams simply can’t be replaced. When I was studying for my CCNA (which I failed by 10 points… ouch), I used a set of CDs with videos on them, provided by my father. (It was a “learnkey” or “learning key” course on the Cisco ICND series, if I remember correctly… It has been over a year since I looked at those disks.)

MP3s could work great, if you can get writers who can describe abstract concepts. Video presentations would work extremely well, because you can actually see an IP passing through a bitmask when you’re subnetting, explaining in a minute what Cisco explains in a few chapters.

It wouldn’t work very well while a person was jogging, but my PDA has video playback on it… I could load an .avi file and study while I’m riding an exercise bike or using a treadmill. It’s also easier to rewind a video file to the start of a topic that went over your head, because you have visual cues to make up for the choppy, backwards audio.
