Introduction

What Is This Book About?

Welcome to the CCNA Practice Questions Exam Cram! The sole purpose of this book is to provide you with practice questions complete with answers and explanations that will help you learn, drill, and review for the 640-802, 640-822, and 640-816 certification exams. The book offers a large number of questions to practice each exam objective and will help you assess your knowledge before you write the real exam. The detailed answers to every question will help reinforce your knowledge about different issues involving the design and configuration of Cisco networks.

Who Is This Book For?

If you have studied the content for the 640-802, 640-822, or 640-816 exams and feel you are ready to put your knowledge to the test, but you are not sure that you want to take the real exam yet, this book is for you! Maybe you have answered other practice questions or unsuccessfully taken the real exam, reviewed, and want to do more practice questions before retaking the real exam; this book is for you, too! Even when the exam is done and you have passed with flying colors and got the CCENT or CCNA certificate in your pocket, keep the book handy on your desktop to look for answers to your everyday Cisco configuration issues.

What Will You Find In This Book?

As mentioned earlier, this book is all about practice questions! The practice questions in the book, some easy and others containing more complicated problem scenarios, are all aimed at raising your confidence level before writing the real exam. You will find questions that, in fact, you will face in real life.

This book is organized according to the objectives published by Cisco for the following exams:

Exam 640-802: CCNA Exam 640-822: ICND1 Exam 640-816: ICND2

x CCNA Practice Questions (Exam 640?802)

The book has been organized to help direct your study to specific objectives. If you are studying only for the ICND1 exam (640-822), you only need to review Chapters 1?6. If you are studying for the ICND2 (640-816) exam, you should focus your studies on Chapters 7?11 (although, reviewing Chapters 1?6 may be helpful). If you are studying for the CCNA all-in-one exam, study through the whole book!

Each chapter corresponds to an exam objective, and in every chapter you find the following three elements:

. Practice Questions--These are the numerous questions that will help you learn, drill, and review exam objectives. Some of the questions are multiple choice, others are matching (simulating the drag-and-drop style questions on the exam), and others are entering configurations (simulating the simulation style questions on the exam). Choose the correct answer based on your knowledge of Cisco networks.

. Quick Check Answer Key--After you have finished answering the questions, you can quickly grade your exam from this section. Only correct answers are given in this section. No explanations are offered yet! Even if you have answered a question incorrectly, do not be discouraged. Just move on! Keep in mind that this is not the real exam. You can always review the topic and do the questions again.

. Answers and Explanations--This section provides correct answers as well as further explanations about the content posed in that question. Use this information to learn why an answer is correct and to reinforce the content in your mind for the exam day.

NOTE

It is not possible to reflect a real exam on a paper product. As mentioned earlier, the purpose of the book is to help you prepare for the exam and not provide you with real exam questions. Neither the author nor Que Publishing can guarantee that you will pass the exam only by memorizing the practice questions given in this book.

You will also find a Cram Sheet at the beginning of the book specifically written for the exam day. The Cram Sheet contains core knowledge that you need for the exam. The Cram Sheet condenses all the necessary facts found in the exam into an easy-to-handle tear card. It is something you can carry with you to the testing center and use as a last-second study aid. Be aware that you cannot take the Cram Sheet into the exam room, though!

xi Introduction

Hints for Using This Book

Because this book is a paper practice product, you might want to complete your exams on a separate piece of paper so that you can reuse the exams over and over without having previous answers in your way. Also, a general rule of thumb across all practice question products is to make sure that you are scoring well into the high 80% to 90% range in all topics before attempting the real exam. The higher percentages you score on practice question products, the better your chances for passing the real exam. Of course, we cannot guarantee a passing score on the real exam, but we can offer you plenty of opportunities to practice and assess your knowledge levels before you enter the real exam.

When you have completed the exam on paper, use the companion MeasureUp CD to take a timed exam. This will further help you gain confidence and make a self-assessment in case you need more study. Your results will indicate the exam objectives in which you need further study or hands-on practice.

Need Further Study?

Are you having a hard time correctly answering these questions? If so, you probably need further review of all exam objectives. Be sure to see the following sister products to this book from Que Publishing:

. CCNA Exam Cram (Exam 640-802) (3rd Edition) by Michael Valentine and Andrew Whitaker (ISBN 0789737124).
