CCNA Wireless Official Exam Certification GuideCCNA Wireless Official Exam Certification GuideIntroduction

Welcome to the world of Cisco Certified Network Associate (CCNA) Wireless! As technology continues to evolve, wireless technologies are finding their way to the forefront. This clearly indicates the progression from a fixed wired type of connectivity to a more fluid, mobile workforce that can work when, where, and how they want. Regardless of your background, one of the primary goals of the new CCNA Wireless certification is to introduce you to the Cisco Unified Wireless Network (CUWN).

In June 2008, Cisco announced new CCNA specialties, including CCNA Security, CCNA Wireless, and CCNA Voice. These certifications, released 10 years after the initial CCNA, represent the growth of Cisco into new and emerging industries. Certification candidates can now specialize into specific areas of study. Figure I-1 shows the basic organization of the certifications and exams used to achieve your CCNA Wireless certification.

Figure I-1 Cisco Certifications and CCNA Wireless Certification Path

As you can see from the figure, a traditional CCNA certification is a prerequisite before you venture into the CCNA Wireless certification.

Goals and Methods

The most important and somewhat obvious goal of this book is to help you pass the Implementing Cisco Unified Wireless Networking Essentials (IUWNE) exam (640-721). In fact, if the primary objective of this book were different, the book title would be misleading; however, the methods used in this book to help you pass the IUWNE exam are designed to also make you much more knowledgeable about how to do your job.

This book uses several key methodologies to help you discover the exam topics that you need to review in more depth so that you can fully understand and remember those details and prove to yourself that you have retained your knowledge of those topics. This book does not try to help you pass by memorization but helps you truly learn and understand the topics. The CCNA Wireless exam is the foundation for Cisco professional certifications to come, and it would be a disservice to you if this book did not help you truly learn the material. Therefore, this book will help you pass the CCNA Wireless exam by using the following methods:


  • Helping you discover which test topics you have not mastered
  • Providing explanations and information to fill in your knowledge gaps
  • Supplying exercises and scenarios that enhance your ability to recall and deduce the answers to test questions
  • Providing practice exercises on the topics and the testing process via test questions on the CD


In addition, this book uses quite a different style from typical certification-preparation books. The newer Cisco certification exams have adopted a style of testing that essentially says, "If you do not know how to do it, you will not pass this exam." This means that most of the questions on the certification exam require you to deduce the answer through reasoning or configuration rather than just memorization of facts, figures, or syntax from a book. To accommodate this newer testing style, I have written this book as a "real-world" explanation of Cisco wireless topics. Whenever possible, key concepts are explained using real-world examples rather than showing tables full of syntax options and explanations, which are freely available at Cisco.com. As you read through this book, you will definitely get a feeling of, "This is how I can do this" rather than, "There is the general syntax I need to memorize," which is exactly what you need for the newer Cisco exams.

Who Should Read This Book?

This book is designed to provide a twofold purpose. The primary purpose is to tremendously increase your chances of passing the CCNA Wireless certification exam. The secondary purpose is to provide the information necessary to deploy a CUWN and a Cisco Mobility Express (CME) network as part of the Smart Business Communications System (SBCS). The new Cisco exam approach provides an avenue to write the book with both a real-world and certification-study approach at the same time. As you read through this book and study the configuration examples and exam tips, you will truly understand how you can deploy a wireless network, while at the same time feel equipped to pass the CCNA Wireless certification exam.

Strategies for Exam Preparation

Strategies for exam preparation will vary depending on your existing skills, knowledge, and equipment available. Of course, the ideal exam preparation would consist of building a small wireless lab with a 2106 wireless LAN controller and an 1131AP, as well as a Cisco Mobility Express (CME) 526 controller and 521 AP. You would also need a switch and a few wireless clients so that you could work through configurations as you read through this book. However, not everyone has access to this equipment, so the next best step you can take is to read through the chapters in this book, jotting notes down with key concepts or configurations on a separate notepad. Each chapter begins with a "Do I Know This Already?" quiz designed to give you a good idea of the chapter content. In some cases, you might already know most of or all the information covered in a given chapter.

After you have read this book, look at the current exam objectives for the CCNA Wireless exam listed on the Cisco website (http://www.cisco.com/certification). If you see areas shown in the certification exam outline that you would still like to study, find those sections in the book and review them. When you feel confident in your skills, attempt the practice exam included on the book CD. As you work through the practice exam, note the areas where you lack confidence, and review those concepts or configurations in the book. After you have reviewed the areas, work through the practice exam a second time and rate your skills. Keep in mind that the more you work through the practice exam, the more familiar the questions will become and the less accurate the practice exam will measure your skills. After you have worked through the practice exam a second time and feel confident with your skills, schedule the real IUWNE (640-721) exam through VUE (http://www.vue.com). You should typically take the exam within a week from when you consider yourself ready to take it so the information is fresh in your mind.

Cisco exams are difficult. Even if you have a solid grasp of the information, many other factors play into the testing environment (stress, time constraints, and so on). If you pass the exam on the first attempt, fantastic! If not, know that this is happens to many people. The next time you attempt the exam, you have a major advantage: You have experienced the exam firsthand. Although future exams might have different questions, the topics and general "feel" of the exam will remain the same. Take some time to study areas from the book where you felt weak on the exam. You must wait a certain period between attempts, so use that time to make yourself more prepared in the areas in which you scored low.

How This Book Is Organized

Although you can read this book cover to cover, it is designed to be flexible and allow you to easily move between chapters and sections of chapters to cover just the material that you need more work with. If you do intend to read all the chapters, the order in the book is an excellent sequence to use.

Preface

CCNA Wireless Official Exam Certification GuideCCNA Wireless Official Exam Certification GuideIntroduction

Welcome to the world of Cisco Certified Network Associate (CCNA) Wireless! As technology continues to evolve, wireless technologies are finding their way to the forefront. This clearly indicates the progression from a fixed wired type of connectivity to a more fluid, mobile workforce that can work when, where, and how they want. Regardless of your background, one of the primary goals of the new CCNA Wireless certification is to introduce you to the Cisco Unified Wireless Network (CUWN).

In June 2008, Cisco announced new CCNA specialties, including CCNA Security, CCNA Wireless, and CCNA Voice. These certifications, released 10 years after the initial CCNA, represent the growth of Cisco into new and emerging industries. Certification candidates can now specialize into specific areas of study. Figure I-1 shows the basic organization of the certifications and exams used to achieve your CCNA Wireless certification.

Figure I-1 Cisco Certifications and CCNA Wireless Certification Path

As you can see from the figure, a traditional CCNA certification is a prerequisite before you venture into the CCNA Wireless certification.Goals and Methods

The most important and somewhat obvious goal of this book is to help you pass the Implementing Cisco Unified Wireless Networking Essentials (IUWNE) exam (640-721). In fact, if the primary objective of this book were different, the book title would be misleading; however, the methods used in this book to help you pass the IUWNE exam are designed to also make you much more knowledgeable about how to do your job.

This book uses several keymethodologies to help you discover the exam topics that you need to review in more depth so that you can fully understand and remember those details and prove to yourself that you have retained your knowledge of those topics. This book does not try to help you pass by memorization but helps you truly learn and understand the topics. The CCNA Wireless exam is the foundation for Cisco professional certifications to come, and it would be a disservice to you if this book did not help you truly learn the material. Therefore, this book will help you pass the CCNA Wireless exam by using the following methods:

Helping you discover which test topics you have not mastered

Providing explanations and information to fill in your knowledge gaps

Supplying exercises and scenarios that enhance your ability to recall and deduce the answers to test questions

Providing practice exercises on the topics and the testing process via test questions on the CD

In addition, this book uses quite a different style from typical certification-preparation books. The newer Cisco certification exams have adopted a style of testing that essentially says, "If you do not know how to do it, you will not pass this exam." This means that most of the questions on the certification exam require you to deduce the answer through reasoning or configuration rather than just memorization of facts, figures, or syntax from a book. To accommodate this newer testing style, I have written this book as a "real-world" explanation of Cisco wireless topics. Whenever possible, key concepts are explained using real-world examples rather than showing tables full of syntax options and explanations, which are freely available at Cisco.com. As you read through this book, you will definitely get a feeling of, "This is how I can do this" rather than, "There is the general syntax I need to memorize," which is exactly what you need for the newer Cisco exams.Who Should Read This Book?

This book is designed to provide a twofold purpose. The primary purpose is to tremendously increase your chances of passing the CCNA Wireless certification exam. The secondary purpose is to provide the information necessary to deploy a CUWN and a Cisco Mobility Express (CME) network as part of the Smart Business Communications System (SBCS). The new Cisco exam approach provides an avenue to write the book with both a real-world and certification-study approach at the same time. As you read through this book and study the configuration examples and exam tips, you will truly understand how you can deploy a wireless network, while at the same time feel equipped to pass the CCNA Wireless certification exam.Strategies for Exam Preparation

Strategies for exam preparation will vary depending on your existing skills, knowledge, and equipment available. Of course, the ideal exam preparation would consist of building a small wireless lab with a 2106 wireless LAN controller and an 1131AP, as well as a Cisco Mobility Express (CME) 526 controller and 521 AP. You would also need a switch and a few wireless clients so that you could work through configurations as you read through this book. However, not everyone has access to this equipment, so the next best step you can take is to read through the chapters in this book, jotting notes down with key concepts or configurations on a separate notepad. Each chapter begins with a "Do I Know This Already?" quiz designed to give you a good idea of the chapter content. In some cases, you might already know most of or all the information covered in a given chapter.

After you have read this book, look at the current exam objectives for the CCNA Wireless exam listed on the Cisco website (http://www.cisco.com/certification). If you see areas shown in the certification exam outline that you would still like to study, find those sections in the book and review them. When you feel confident in your skills, attempt the practice exam included on the book CD. As you work through the practice exam, note the areas where you lack confidence, and review those concepts or configurations in the book. After you have reviewed the areas, work through the practice exam a second time and rate your skills. Keep in mind that the more you work through the practice exam, the more familiar the questions will become and the less accurate the practice exam will measure your skills. After you have worked through the practice exam a second time and feel confident with your skills, schedule the real IUWNE (640-721) exam through VUE (http://www.vue.com). You should typically take the exam within a week from when you consider yourself ready to take it so the information is fresh in your mind.

Cisco exams are difficult. Even if you have a solid grasp of the information, many other factors play into the testing environment (stress, time constraints, and so on). If you pass the exam on the first attempt, fantastic! If not, know that this is happens to many people. The next time you attempt the exam, you have a major advantage: You have experienced the exam firsthand. Although future exams might have different questions, the topics and general "feel" of the exam will remain the same. Take some time to study areas from the book where you felt weak on the exam. You must wait a certain period between attempts, so use that time to make yourself more prepared in the areas in which you scored low.640-721 IUWNE Exam Topics

    The reason for my reading of the CCNA Wireless Official Exam Cer

    The reason for my reading of the CCNA Wireless Official Exam Certification Guide (CCNA IUWNE 640-721) was looking for certification knowledge for wireless but also understand more practical real world examples of wireless solutions and deployments. The CCNA Wireless Official Exam Certification Guide was a great book as soon as I start reading the book as was able to start correlating the little practical knowledge I had around Wireless with the formal training and the knowledge required for the CCNA Wireless Official Certification Exam.

    If you have some basic and practical knowledge around Wireless this book will allow you to start linking the dots for your certification exam and to improve your practical knowledge around Wireless.

    From the first page the book focus on real world knowledge and understanding of Wireless solutions. The book goes straight to the point. The chapters are developed in way that you have an overall view of the chapter objective, as a 10,000 feet view but through the chapter you land everything very nicely into the objectives and what are the key knowledge you need to have for your daily work and also your certification exams. I need to mention that since my wireless knowledge is based on the fundamental blocks, I have some difficulty on some of the chapters to understand the concepts. This was on certain topics I have not read about it.

    The books has this different key points where relates the knowledge to a key topic for the certification exam or a key concept, which are useful when studying for a certification. The best of the key concept is that you can use them as knowledge points for you daily work to be used on your real world.

    The author of this book Brandon Carroll wrote a real world certification guide that can be use on any project you want to start. You start reading the book and you can start planning a wireless project from scratch into the building blocks and some high level scenarios not all but a couple of good high level concepts. I think the book works as a learning guide to develop wireless knowledge for you daily job for designing and planning but in addition for implementing, operating and optimizing a wireless infrastructure.

    One more thing that I need to outline of the book is the real world example it uses to explain the different concepts of the Wireless Solutions. In addition one more thing that people never do is to read or refer to the appendix section but for this book you really need to put attention since it gives you more detail on the real world scenarios that explains how Wireless Solutions are apply to. Finally on the appendix there is one very interesting which contains material that can be used to build all the knowledge needed for the certification exam.

    On every chapter there is a quiz that allows you to check you knowledge at the beginning of the chapter and at the end of the chapter in order to follow a process for your certification and you daily wireless solution process.

    It is a book that builds knowledge with the content, you will see that the 20 chapters it contains cover the complete fundamentals for the certification and knowledge to work your wireless projects.

    One additional and great feature is the possibility to have a copy of the book on electronic format. In this time of mobility, you will be able to have a copy of the book when you buy the print version. Last but not least the CD included on the book is another great feature which includes great material like a practice exam for your certification.

    I cannot stop reiterating that this book is a mandatory field guide for any person that is working on the IT industry delivering any project, service or anything that relates to it. Also is a very good introduction to the Wireless Technologies because you will have the fundamentals and then built toward more complex knowledge for your daily job or the CCNA Wireless certification exam.

    The author built a book that has a lot of very specific useful information.

    I will recommend the book as a daily personal reference because you can find out concepts that will help you on your daily work when you’re are delivering a project and applying Wireless to your daily activities. Since I got the book I start using it a guideline to develop my Wireless designing or deploying infrastructures in an enterprise or a service provider.

    This is a must have book for daily reference and guidelines

    One more feature that I have not try but would like to implement is the offer of the online edition, this is great since this book I recommended as a job related book.

    My rating of the book is a 5, excellent book.

    Wait until Lammie's book comes out

    After using this book to prepare, I wasn't able to pass the test. Check how many errata sheets are available for it and compound the issue with the fact that Cisco asks questions on their test not covered in this book. You can spend your own $250 for a voucher if you'd like to prove me wrong. This is the poorest exam certification I've ever seen come from Cisco.

    Practitioner's Review by Darby Weaver, Network Engineer

    CCNA Wireless Official Exam Certification Guide (CCNA IUWNE 640-721)
    by Darby Weaver


    Let me start by saying that I used the book to help me deploy not one Wireless LAN Controller but also standardize the configuration on two other Wireless LAN Controllers in an Enterprise "Medical Grade Network" to support the State of Florida. This means I used the wireless mobility features presented in the book.

    I'm the network engineer for the state. I had to prepare my network for the Wireless LAN Controllers, convert APs from Autonomous to Lightweight, prepare the infrastructure in terms of DHCP and LWAPP proxies using Cisco routers and switches, configure DHCP, and I even configured DNS, and I used this book to help me perform those tasks successfully.

    I'm a troubleshooter as a network engineer. In the heat of battle, I needed to perform a variety of debug and command line applications. I used this book to help me learn to do these tasks properly and succinctly. This book by Mr. Carroll helped me look to be quite the superstar.

    Quote from my manager:

    "Darby you seem to know these Cisco Wireless LAN Controllers quite well." I told him the truth that they were still new to me and I was still learning them. He then complimented me on my work performed with them thus far. He told me he'd have thought I was using them all along. That's just too kewl! Books like this one can do that for you. I love Cisco Press and I love my library. This book is a keeper!!!

    Priceless!!!

    While using this book, I had two unfortunate events. My Wireless Mobility Anchor was broken not once but twice (perhaps too many hands the first time) and the second time I actually lost the Anchor itself. So this book was truly a life-saver and allowed me to work correctly through resolving the problem. In either case, I opened a TAC case and worked with TAC and used my book to help me along since I was still a baby with these controllers on the first occasion and by the second unplanned outage, I found myself using the book's correct order of operations to completely rebuild the anchor in a matter of minutes after allowing 4 TAC support specialists a total of just over 8 hours to fix the problem. I guess they did not have their copy handy. I did. How kewl is that?

    Let's see...

    Umm... Upgrading and APs to LAP went well. Registering the APs to the controller went great. I have the opportunity to work with tagged and untagged LAG and single interfaces. That went well.

    I had a lot of positive experiences with the book and I think you will too.

    I did not have the Small Business version of the Wireless LAN Controller to actually work with but it was covered in the text.


    Quite frankly I love Cisco Press book for the practical carrots and beats of knowledge they present that allow me to better perform my job.

    I'm writing my review a bit late. There is now errata out for the book.

    Let talk about the book for what it is:

    It is a Cisco certification prep tool. That's it. That means it is simply one tool used to help a person attain a Cisco certification. In my opinion it has done this and done this well.

    This book alone will not relieve the exam candidate of the requirement to perform further study and perform hands-on tasks with real equipment - Autonomous APs, Lightweight APs, and Wireless LAN Controllers. This must be done to achieve any Cisco certification.

    Best for the test but just an alright book

    I read this book just to see the material and though it was alright, however the material to prepare for the test is probably the best since there's not a lot of books to prepare for the exam.
