Are there any tutorials on WAN technologies in this site. If so where. Else any other good place to know about WAN technologies. I am preparing for CCNA exam. I will be taking next month. I don't know anything about WAN like ISDN, Frame Relay.
Thanks to this site that Im a little bit comfortable with ethernet technolgies because of all the tutorial stuff here.
Nope I don't think we have any specific WAN technology covered in the material on the site just yet. You will need to know ISDN and frame-relay for the CCNA as well as some basics about ATM etc.
However the info you need is very straightforward, you can pick it up from lots of places on the net. If I can convince my friend to give me back my damn CCNA Study Guide, I'll post a brief summary of the most important points.
