Getting Started

This Getting Started section provides some valuable advice about how to use the study features in this book. Taking a few minutes to read through this short section before going on to Chapter 1 helps you get the most out of the book, regardless of whether you are using it with the end goal of preparing for the CCNA Routing and Switching certification exams or just learning basic networking concepts.

A Brief Perspective on Cisco Certification Exams

Cisco sets the bar pretty high for passing the ICND1, ICND2, and/or CCNA exams. Most anyone can study and pass these exams, but it takes more than just a quick read through the book and the cash to pay for the exam.

The challenge of these exams comes from many angles. Each of these ...
