This book, directly inspired from Cisco training courses given for more than 10 years at several IT training schools, is designed to provide lab skills necessary for passing the new CCNA exam (200-301). It can also be used as a configuration reference for Cisco routers and switches. This book is for everyone studying for the CCNA, but I consider it one of the best books written in the world in this field at all. I have read dozens of CCNA lab manuals and I know what I am saying. The CCNA Lab Guide provides the readers with 21 labs designed to emphasize hands-on practice to reinforce their configuration skills. In order to allow readers to be familiar with several simulation tools, we used the following - Cisco Packet Tracer. - GNS3. - EVE-NG. Our experience in the IT field has shown us that a course will only be well understood if we succeed in doing a lab and understand its solution. That’s why we recommend to readers to start working on the labs on their own and only look at the solution to verify their work.
