Read an Excerpt
The CompTIA Network+ exam has become the leading introductory-level network certification available today. Network+ is recognized by both employers and industry giants such as Microsoft and Novell as providing candidates with a solid foundation of networking concepts, terminology, and skills. The Network+ exam covers a broad range of networking concepts, to prepare candidates for the technologies they are likely to be working with in today's network environments.
This book is your one-stop shop. Everything you need to know to pass the exam is in here. You do not have to take a class in addition to buying this book to pass the exam. However, depending on your personal study habits or learning style, you might benefit from buying this book and taking a class.
Exam Preps are meticulously crafted to give you the best possible learning experience for the particular characteristics of the technology covered and the actual certification exam. The instructional design implemented in the Exam Preps reflects the task- and experience-based nature of CompTIA certification exams. The Exam Preps provide the factual knowledge base you need for the exams but then take it to the next level, with exercises and exam questions that require you to engage in the analytic thinking needed to pass the Network+ exam.
CompTIA recommends that the typical candidate for this exam have a minimum of nine months experience in network support and administration. In addition, CompTIA recommends that candidates have preexisting hardware knowledge such as CompTIA A+ certification.
How This Book Helps You
This book takes you on a self-guided tour of all the areas covered by the Network+ exam and teaches you the specific skills you need to achieve your certification. The book also contains helpful hints, tips, real-world examples, and exercises, as well as references to additional study materials. Specifically, this book is set up to help you in the following ways:
- OrganizationThis book is organized by individual exam objectives. Every objective you need to know for the Network+ exam is covered in this book. We present the objectives in an order as close as possible to that listed by CompTIA. However, we do not hesitate to reorganize them where needed to make the material as easy as possible for you to learn. We also make the information accessible in the following ways:
- The full list of exam units and objectives is included in this introduction.
- Each chapter begins with a list of the objectives to be covered.
- Each chapter also begins with an outline that provides an overview of the material and the page numbers where particular topics can be found.
- The objectives are repeated where the material most directly relevant to it is covered.

Network Hardware and Software Requirements
As a self-paced study guide, Network+ Exam Prep 2 is meant to help you understand concepts that must be refined through hands-on experience. To make the most of your studying, you need to have as much background on and experience with both common operating systems and network environments as possible. The best way to do this is to combine studying with work on actual networks. These networks need not be complex; the concepts involved in configuring a network with only a few computers follow the same principles as those involved in configuring a network that has hundreds of connected systems. This section describes the recommended requirements you need to form a solid practice environment.
To fully practice some of the exam objectives, you need to create a network with two (or more) computers networked together. To do this, you need an operating system. CompTIA maintains that the exam is vendor neutral, and for the most part it appears to be. However, if there were a slight tilt in the exam questions, it would be toward Microsoft Windows. Therefore, you would do well to set up a small network using a Microsoft server platform such as Windows 2000/2003 server. In addition, you need clients with operating systems such as Windows 2000/XP, Linux, and Mac. When you really get into it, you might want to install a Linux server as well because you are most certainly going to be working with them in the real world. The following is a detailed list of the hardware and software requirements needed to set up your network:
- A network operating system such as Windows Server or Linux
- Client operating system software such as Windows XP, Mac OS X, or Linux
- Modern PC offering up-to-date functionality including wireless support
- A minimum 1.5GB of free disk space
- A CD-ROM or DVD drive
- A network interface card (NIC) for each computer system
- Network cabling such as Category 5 unshielded twisted-pair
- A two-port (or more) miniport hub to create a test network
- Wireless devices
It's easy to obtain access to the necessary computer hardware and software in a corporate business environment. It can be difficult, however, to allocate enough time within the busy workday to complete a self-study program. Most of your study time will occur after normal working hours, away from the everyday interruptions and pressures of your regular job.
Advice on Taking the Exam
More extensive tips are found in the "Study and Exam Prep Tips" section, but keep this advice in mind as you study:
- Read all the materialCompTIA has been known to include material that is not expressly specified in the objectives. This book includes additional information that is not reflected in the objectives, in an effort to give you the best possible preparation for the examinationand for your real-world experiences to come.
- Complete the exercises in each chapterThey will help you gain experience in using the specified methodology or approach. CompTIA exams may require task- and experienced-based knowledge and require you to have an understanding of how certain network procedures are accomplished.
- Use the exam questions to assess your knowledgeDon't just read the chapter content; use the exam questions to find out what you know and what you don't know. If you are struggling, study some more, review, and then assess your knowledge again.
- Review the objectivesDevelop your own questions and examples for each objective listed. If you can develop and answer several questions for each objective, you should not find it difficult to pass the exam.
Note - Exam-Taking Advice Although this book is designed to prepare you to take and pass the Network+ certification exam, there are no guarantees. Read this book, work through the questions and exercises, and when you feel confident, take the practice exam and additional exams provided in the MeasureUp test software. Your results should tell you whether you are ready for the real thing.
When taking the actual certification exam, make sure that you answer all the questions before your time limit expires. Do not spend too much time on any one question. If you are unsure about the answer to a question, answer it as best as you can; then mark it for review after you have finished the rest of the questions. Note that this advice does not apply if you are taking an adaptive exam. In that case, take your time on each question because there is no opportunity to go back to a question.
Remember that the primary objective is not to pass the exam but to understand the material. When you understand the material, passing the exam should be simple. Knowledge is a pyramid; to build upward, you need a solid foundation. This book and the Network+ certification are designed to ensure that you have that solid foundation.

I used this book plus the practice questions book and was able to pass the test. There were a few questions that I don't think the book covered but they could have been unscored questions.
