IntroductionThe CompTIA Network certification is a popular certification for those enteringthe computer networking field. Although many vendor-specific networking certifications are popular in the industry, the CompTIA Network certification is uniquein that it is vendor neutral. The CompTIA Network certification often acts as astepping-stone to more specialized and vendor-specific certifications, such as thoseoffered by Cisco Systems.In CompTIA Network , the topics are mostly generic in that they can apply tonetworking equipment regardless of vendor. Although the CompTIA Network isvendor neutral, network software and systems are implemented by multiple independent vendors. In that light, several of the exercises, examples, and simulations inthis book include using a vendor’s configuration and technology, such as MicrosoftWindows operating systems or Cisco Systems routers and switches. More detailedtraining for a specific vendor’s software and hardware can be found in books andtraining specific to that vendor.Who Should Read This Book?This book was written with two audiences in mind—those who want to learn allthey can about networking technology, and those who want to pass the CompTIANetwork exam. I think that both groups are going to be very impressed with thebreadth of technologies this book details. Although it would be impossible to coverevery topic found in networking today, this book manages to cover all the massiveareas that make networking the exciting field so many want to learn.Readers will range from people who are attempting to attain a position in the ITfield to people who want to keep their skills sharp or perhaps retain their job because of a company policy that mandates they take the new exams. This book is alsofor the reader who wants to acquire additional certifications beyond the Network certification (for example, the Cisco Certified Network Associate [CCNA] certification and beyond). The book is designed in such a way to offer easy transition tofuture certification studies.
Introduction xxixResourcesThis book comes with a wealth of digital resources to help you review, practice, andassess your knowledge. The end of each chapter contains a review section that references several of these tools, and you should be sure to use them as you completeeach chapter to help reinforce the knowledge you are learning. You can use themagain after you finish the book to help you review and make sure you are fully prepared for the exam.Here’s a list of resources available on the companion website: Interactive glossary flash card application Interactive exam essentials appendix Performance-based exercises CompTIA Network Hands-on Lab Simulator Lite Software for examN10-007 The Pearson Test Prep practice test software Video training on key exam topics Memory Table review exercises and answer keys A study planner tool Instructions to redeem your Network certification exam voucher, providing a10% discount on the examTo access the companion website, follow these steps:Step 1. Go to p 2. Either log in to your account (if you have an existing account already) orcreate a new account.Step 3. Enter the ISBN of your book (9780789759818) and click Submit.Step 4.

Using the Pearson Test Prep practice test engine, you can either

The software also has a flash cardmode that allows you to challenge yourself to answer the questions without seeingthe multiple-choice answers.The Pearson Test Prep software is available both online and as a Windows desktopapplication that you can run offline. The online version can be accessed atwww.pearsontestprep.com. This version can be used on any device that has anInternet connection, including desktop computers, laptop computers, tablets, andsmartphones. It is optimized for viewing on screens as small as a standard iPhonescreen. The desktop application can be downloaded and installed from the companion website.Note The desktop application is a Windows-based application, so it is only designed to run on Windows. Although it can be run on other operating systems using aWindows emulator, other operating systems are not officially supported on the desktop version. If you are using an OS other than Windows, you may want to considerusing the online version instead.Accessing the test engine is a two-step process. The first step is to either install thesoftware on your desktop or access the online version website. However, the practice exam (that is, the database of CompTIA Network exam questions) is not available to you until you register the unique access code that accompanies your book.The cardboard sleeve in the back of the physical book includes a piece ofpaper. The paper lists the access code for the practice exam associated with this book.Make sure you keep the access code even after you have registered your exam, as youmay need to refer to it later.
