CCNA ICND Exam Certification Guide is a best-of-breed Cisco(r) exam
study guide that has been completely updated to focus specifically on the
objectives for the new CCNA ICND exam. Senior instructor and best-selling author
Wendell Odom shares preparation hints and test-taking tips to help you identify
areas of weakness and improve both your conceptual and hands-on knowledge. This
new edition is organized in a modular fashion, segmenting larger chapters into
smaller, more easily digestible components. Material is presented in a concise
manner, focusing on increasing your retention of exam topics.
CCNA ICND Exam Certification Guide presents you with an organized test
preparation routine through the use of proven series elements and techniques.
"Do I Know This Already?" quizzes open each chapter and allow you to decide how
much time you need to spend on each section. Chapter subject lists and
Foundation Summary tables make referencing easy and give you a quick refresher
whenever you need it. Challenging chapter-ending review questions help you
assess your knowledge and reinforce key concepts. Scenario-based exercises help
you think about exam objectives in real-world situations, thus increasing recall
during exam time. The companion CD-ROM contains a powerful new testing engine
that allows you to focus on individual topic areas or take complete, timed exams
from ICND and unified CCNA test banks. The assessment engine also tracks your
performance and provides feedback on a module-by-module basis, presenting
question-by-question remediation to the text and laying out a complete study
plan for review. The CD-ROM also includes a wealth of hands-on practice
exercises and a copy of the Boson NetSim(tm) for CCNA ICND, Learning Edition,
network simulation software that allows you to practice your hands-on skills in
a virtual lab environment that has been customized for the labs in the book.
Well-regarded for its level of detail, assessment features, and challenging
review questions and hands-on exercises, this book helps you master the concepts
and techniques that will enable you to succeed on the exam the first time.
CCNA ICND Exam Certification Guide is part of a recommended study
program from Cisco Systems(r) that includes simulation and hands-on training
from authorized Cisco Learning Partners and self-study products from Cisco
Press. To find out more about instructor-led, e-learning, and hands-on
