ICND1 and ICND2 break down

The content is migrated from friend site kl2217.wordpress.com.
If you haven't decided what CCNA test to take, read this post first.

The author created this free CCENT and CCNA study guide by collecting various free multimedia resources from the network, including a lot of youtube videos. Also check out the CCNA Lab for the labs corresponding to this tutorial, and verify your knowledge with pre-make Practice Exams .

Do It Yourself (DIY) is the best way of learning TCP/IP network, therefore, I highly recommend you to download wireshark and packet tracer. With wireshark, you can capture your network traffic and see exactly what's going on under the hood; with packet tracer, you can set up LAN and WAN virtually and do experiments on them.

Whenever you need to learn more about a CCENT and CCNA key word, use the Site Search at the upper left conner.

Good luck with your CCENT and CCNA test!
