The Unofficial JNCIE-ENT Prep Guide

A guide to help you prepare for your JNCIE-ENT Lab exam

About the Book

This is a workbook with the focus on studying for and taking your JNCIE lab exam.  I used the JNCIE-ENT syllabus as a guide while writing this workbook.  I took each exam topic and explained it, configured it, and showed the options for that item.  This workbook is over 500 pages of information to help you study for your JNCIE-ENT lab exam.
