Introduction
Welcome to CompTIA® Network+® Practice Tests: Exam N10-008. This book gives you a focused, timesaving way to review your networking knowledge and prepare to pass the Computing Technology Industry Association (CompTIA) Network+ exam. The book combines realistic exam prep questions with detailed answers and two complete practice tests to help you become familiar with the types of questions that you will encounter on the Network+ exam. By reviewing the objectives and sample questions, you can focus on the specific skills that you need to improve before taking the exam.
How This Book Is Organized
The first five chapters of this book are based on the five objective domains published by CompTIA for the N10-008 Network+ exam. There are approximately 200 questions for each objective domain, covering each of the suggested topics. The next two chapters each contain a 100-question practice test covering all of the objective domains. Once you have prepared for each of the objective domains individually, you can take the practice tests to see how you will perform on the actual exam.
Objective Map
The following table gives you the extent, by percentage, that each domain is represented on the actual examination, and where you can find questions in this book that are related to each objective.
| Objective | Percentage of Exam | Chapter |
|---|---|---|
| 1.0 Networking Fundamentals | 24% | 1 |
| 2.0 Network Implementations | 19% | 2 |
| 3.0 Network Operations | 16% | 3 |
| 4.0 Network Security | 19% | 4 |
| 5.0 Network Troubleshooting | 22% | 5 |
Who Should Read This Book
CompTIA recommends, but does not require, that candidates for the Network+ exam meet the following prerequisites:
CompTIA A+ certification or equivalent knowledge
At least 9 to 12 months of work experience in IT networking
CompTIA's certification program relies on exams that measure your ability to perform a specific job function or set of tasks. CompTIA develops the exams by analyzing the tasks performed by people who are currently working in the field. Therefore, the specific knowledge, skills, and abilities relating to the job are reflected in the certification exam.
Because the certification exams are based on real-world tasks, you need to gain hands-on experience with the applicable technology in order to master the exam. In a sense, you might consider hands-on experience in an organizational environment to be a prerequisite for passing the Network+ exam. Many of the questions relate directly to specific network products or technologies, so use opportunities at your school or workplace to practice using the relevant tools. Candidates for the exam are also expected to have a basic understanding of enterprise technologies, including cloud and virtualization.
How To Use This Book
Although you can use this book in a number of ways, you might begin your studies by taking one of the practice exams as a pretest. After completing the exam, review your results for each Objective Domain and focus your studies first on the Objective Domains for which you received the lowest scores.
As this book contains only practice questions and answers, the best method to prepare for the Network+ exam is to use this book along with a companion book that provides more extensive explanations for the elements covered in each objective domain. Todd Lammle's CompTIA® Network+® Study Guide: Exam N10-008 provides complete coverage of all the technology you need to know for the exam.
After you have taken your pretest, you can use the chapters for the objective domains in which you need work to test your detailed knowledge and learn more about the technologies involved. By reviewing why the answers are correct or incorrect, you can determine if you need to study the objective topics more.
What's Next
The next step is to review the objective domains for the Network+ N10-008 exam and think about which topics you need to work on most. Then, you can turn to the appropriate chapter and get started. Good luck on the exam.
