CCENT ICND1 100-101 Cert Guide

This book was written to help you pass the CCENT exam (ICND1), a certification from Cisco, the world's most famous company that manufactures and sells networking equipment. I've tried to cover every topic from the CCENT curriculum and explain it in an easy and fun way.

This book covers the latest version of the exam (100-101), available since 2013. The book follows the Cisco organization of topics. We start with basics, explaining what really a computer networks is, the difference between the OSI and TCP models, what an IP address is, how to configure an IP address on a Cisco router, etc. In later lessons we will go through some more advanced topics such as routing protocols, IPv6, NAT, ACLs...
