CCNA LAB MANUAL VERSION 4 VOLUMES 1 & 2 (questions guide)



CCNA Lab Manual Version 4 Volumes 1 and 2 - By Matthew Basham. | PDF | English |


Preface
This manual was developed to prepare students for hands-on training to accompany classroom lectures on CISCO networking theory for the CISCO CCNA 3.0 (#640-607) examination. These labs are intended to supplement and enhance the Cisco Networking Academy Program with additional information, explanations, and laboratory materials, not to replace them. If you are looking for a lot of theory, then you have got the wrong book.

All labs and exercises contain four basic parts:
1. An objective section giving a brief topic for exploration in the lab or exercise
2. A tools and materials list
3. Steps needed to complete the lab or exercise
4. Supplemental lab or exercise challenge activities


Some of the labs contain guest router names that are borrowed from computer security history. I do this to spice up the labs a bit and give you a cross-reference and some history of computer security.
