So yeah, theres quite a few errors and grammatical incontinuities, its short, and it gives no insight into the story besides a nightmare. T It could be better. I want to see at least a first chapter before condemning it though.Was this review helpful? Yes NoThank you for your feedback. Report this reviewThank you, this review has been flagged.

Jack turned over in his bed while he slept. He was haveing another nightmare. In this nightmare, invisable hands griped his body, squeezing the air out of his lungs. He gasped for breath and struggled to get free. A dark, cold laugh echoed through his mind as his legs failed in the air. "Give in, Jack!" the cold voice whispered. "You're mine!"<p> Jack is only a normal looking 13 year old boy. One with the same terrible dream each night. And when he was convinced that he should just give into these dreams, the nightmare he's been haveing since he was 10, come to life. <p>part one at next result.Was this review helpful?

Great reference as well as Study Guide
This book is a great study guide and it serves a very useful long term purpose as a great reference tool. I am also using it as one of my study materials preparing for the Cisco CCNA exam.Was this review helpful? Yes NoThank you for your feedback.

I really like the way Cisco presents the material. This guide has just enough detail to clearly cover the topic but not overwhelm. The use of tables, figures, examples, and bulleted points, make it an easy read. Key topics for the exam are clearly marked. Each chapter begins with a quiz which is helpful in deciding how much time to spend studying that chapter. Each chapter also ends with a Q&A section which serves to ensure that you understand the material. The last 2 chapters of the guide tie it all together by providing real world comprehensive scenarios and tools for final exam preparation.
The CD contains supplemental materials including:
* Memory Tables and the Memory tables answer key in PDF format. This is similar to a cheat sheet and provides another good tool for certification preparation.
* The installer for the exam engine for the practice test and the process to activate it
* Link to register this guide so that you can receive any update
The exam engine installed and ran well on Windows 7. It provides 2 modes, study and practice exam. You can choose to include the book questions as well as the practice exam questions. You can include or exclude questions for each exam objective. You can choose to order by objective or not. You can choose the number of questions to select and a time limit. You can move forward and backward through the questions. You can also review the answer and an explanation at any point in time. This exam engine also allows you to save notes for any specific question which is a feature I have not seen before. When you click the Grade Exam button, you are provided with detailed feedback on your results. This includes feedback on each objective as well as each question.
I highly recommend this book as either a study guide and/or a great reference tool for networking concepts.

A good Cisco DESGN exam book
CCDA 640-864 Official Cert Guide is a well written and easy to understand book. The book's goal is to help the readers pass the 640-864 Cisco DESGN exam. All chapters start with the "Do I know this already" quiz, followed by the introduction of the foundation topics and finished with Q&A.Was this review helpful? Yes NoThank you for your feedback.

The book covers the design of Cisco internetwork infrastructure from the basic network design, LAN and WAN design to security, voice and video design.
The first three chapters mainly discuss the network design method, Cisco enterprise architecture model and enterprise LAN design. It illustrates the usual campus layer design (core-distribution-access) along with the best design practices for large, medium or small LAN sites. It covers redundancy protocols like HSRP, VRRP and GLBP in 2 pages but its explanation is very concise and good.
The data center design chapter touches many different topics from power, cooling, cabling to virtualization. There are a lot of acronyms like VSS, VRF, vPC, VSAN and others. The book does not explain them clearly. Readers will need to check the references and recommended readings at the end of the chapter to get a better understanding. There are also a lot of Cisco equipment (Nexus switches, ASA firewall and others) being mentioned. I know this is a design book but it should at least dedicate one chapter to introduce these Cisco equipments for readers who have no knowledge about Cisco products. Chapter 7 WAN design briefly illustrates Cisco router and switching solution only but not the new Nexus switches and other security products.
The book does a good job explaining the WAN technologies and designs especially MPLS. In two pages, it is able to provide the summary on how MPLS works and the design for layer 2 and layer 3 MPLS. The book does an excellent job describing IPv4 and IPv6 and their comparison. I do recommend reading Shannon McFarland's IPv6 for Enterprise Networks for readers who want to know more about IPv6.
The book also covers routing protocol topics well. Not only it describes how each routing protocols like RIP, EIGRP and OSPF work but it also explains these protocols in IPv6 networks. The chapter also explains route manipulation as well as BGP and its attributes. It does not cover ISIS. I find it interesting that the book dedicates 8 pages to explain IP multicast while it only reserves 2 pages for MPLS.
Chapter 16 discusses three network case study scenarios and the final chapter is about final exam preparation where it identifies the tool and tips to use the material for the study.
This book is relatively easy to read and understand for readers who are very familiar with Cisco switching and routing concepts.
I recommend this book without hesitation. I rate this book 5 out of 5 stars. The book will help the readers pass the exam. However, I still recommend the readers to access the Cisco web site to get more information for their study in addition to reading this book

good exam preparation
The dominant computer networking company is Cisco. So if you aspire to be a network manager, being certified in Cisco products can be an important qualification. To help you pass the CCDA DESGN exam, the authors of this book compiled a massive study aid.Was this review helpful? Yes NoThank you for your feedback.

Each chapter is prefaced by a 'Do I know this already' quiz. A few pages of multiple choice questions. None seems particularly hard or conceptually deep. This is a nice format for what is meant to be a purely functional, single purpose book. Perhaps like the venerable Schaum's Outline series, fleshed out with more narrative. I wonder why I don't see this more often. Often texts for exam preparation have quizzes at the end of chapters; not at the start.
As usual with most Cisco books, the network diagrams are well drawn and usually simple. An invaluable aid to understanding the accompanying narrative. Often, the diagrams reduce the discussion of a network topology or routing to the minimal essence in graphical form. This pictorial representation might be what really makes coherent of a lot of text to the reader.
The book can serve another purpose. The grouping of information into the various chapters is a handy way to study networking. Several of the chapters, like those on Internet Protocol version 4 and version 6, can be regarded as quite generic; ie. not about Cisco products and their specific properties. Likewise with the chapter on managing security. This talks about 3rd party tools (think Nmap, Nessus and Kismet as examples) and the overall design of a network.
Don't forget the accompanying CD. While the book has those quizzes, the CD is meant as a full test run, after you have hopefully assimilated the chapters. If you are indeed preparing for the exam and have gotten this book, sittin thru the CD is vital feedback on your preparation status. If you find that you've scored too low on the CD exam, then consider postponing taking the real exam while you reread [more carefully this time!] the book. This can easily repay the cost of the book, compared to having to retake the exam.
