A+ Certification Training Guide, Fifth Edition, is designed for those with the goal of certification as an A+ certified technician. It covers both the Core Hardware Service Technician (220-301) and Operating System Technologies (220-302) exams.
These exams measure essential competencies for a microcomputer hardware service technician with six months of on-the-job experience. You must demonstrate knowledge that would enable you to properly install, configure, upgrade, troubleshoot, and repair microcomputer hardware. This includes basic knowledge of desktop and portable systems, basic networking concepts, and printers. You also must demonstrate knowledge of safety and common preventive maintenance procedures.
This book is your one-stop shop. Everything you need to know to pass the exams is in here. You do not have to take a class in addition to buying this book to pass the exam. Depending on your personal study habits or learning style, however, you might benefit from buying this book and taking a class.
This book also can help advanced users and administrators who are not studying for the exam but are looking for a single-volume technical reference.
This book provides a self-guided tour of all the areas covered by the Core Hardware Service Technician and Operating System Technologies exams and identifies the specific skills you need to achieve your A+ certification. You also will find the features that make Que's training guides so successful: clear organization, helpful hints, tips, real-world examples, and step-by-step exercises. Specifically, this book is set up to help you in the following ways:
Organization— This book is organized according to individual exam objectives. This book covers every objective that you need to know for the Core Hardware Service Technician and Operating System Technologies exams. The objectives are covered in the same order as they are listed by the certifying organization, CompTIA, to make it as easy as possible for you to learn the information. We also have attempted to make the information accessible in the following ways:
The Study and Exam Prep Tips section will help you develop study strategies. It also provides valuable exam-day tips and information.
This introduction includes the full list of exam topics and objectives.
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 indicating where you can find particular topics.
Objectives are repeated within the text where the material most directly relevant to them is covered.
Information on where the objectives are covered is also conveniently condensed on the tearcard at the front of this book.
Instructional features— This book has been designed to provide you with multiple ways to learn and reinforce the exam material. Following are some of the helpful methods:
Objective explanations— As mentioned previously, each chapter begins with a list of the objectives covered in the chapter. In addition, immediately following each objective is an explanation in a context that defines it more meaningfully.
Study strategies— The beginning of each chapter also includes strategies for studying and retaining the material in the chapter, particularly as it is addressed on the exam.
Test tips— Exam tips appear in the margin to provide specific exam-related advice. Such tips might address what material is covered (or not covered) on the exam, how it is covered, mnemonic devices, and particular quirks of that exam.
Key terms— A list of key terms appears at the end of each chapter. This list highlights terms and concepts you should recognize. Where possible, such terms have been italicized in the text.
Notes— These paragraphs appear in the margin and contain various kinds of useful information such as tips on technology or administrative practices, historical background on terms and technologies, or side commentary on industry issues.
Warnings— When you are using sophisticated technology improperly, the potential for mistakes or even catastrophes to occur is ever-present. Warnings appear in the margin to alert you to such potential problems.
Lab exercises— Fifty-four exercises or lab procedures are included on the CD that accompanies this book, providing you with more opportunities for hands-on learning and reinforcement of the concepts.
Challenges— These instructional elements require you to analyze a situation and come up with a solution to a technical problem. They are included here in anticipation of the application questions that will begin to appear in the A+ exams. Answers appear in the “Apply Your Knowledge” section.
Extensive practice test options— This book provides numerous opportunities for you to assess your knowledge and to practice for the exam. The practice options include the following:
Review Questions— These questions appear in the “Apply Your Knowledge” section. They reflect the kinds of multiple-choice questions that appear on the A+ exams. Use them to practice for the exam and to help you determine what you know and what you need to review or study further. Answers and explanations for them are provided.
Practice exam— A practice exam is included in the “Final Review” section for each exam (as discussed later).
PrepLogic— The PrepLogic software included on the CD that accompanies this book provides even more practice questions. You also can purchase more questions; these questions are already on the CD and merely need to be “unlocked” so that you can access them.
Final Review— This part of the book provides the following three valuable tools that can help you prepare for the exam:
Fast Facts— This condensed version of the information contained in the book will prove extremely useful for last-minute review.
Practice Exam— A full practice test for each of the exams is included. Questions are written in the styles used on the actual exams. Use it to assess your readiness for the real thing.
Video Presentations— This edition of the book includes approximately two hours of video presentations provided by world-renowned computer repair author Scott Mueller. These video presentations can be found on the CD-ROM located inside the back cover of the book.
The book includes several valuable appendixes as well, including a glossary (Appendix A), an overview of the A+ certification program (Appendix B), a description of what is on the CD-ROM (Appendix C), and an explanation of the PrepLogic test engine (Appendix D).
These and all the other book features mentioned previously will enable you to thoroughly prepare for the exam.

As a self-paced study guide, this book was designed with the expectation that you will use your computer as you follow along through the exercises.

More extensive tips are located in the section titled “Study and Exam Prep Tips,” but keep this advice in mind as you study:
Read all the material. Make sure that your exam preparation is thorough. Do not just drop into the book and read around. Read through all the material. This book includes additional information not reflected in the objectives in an effort to give you the best possible preparation for the examination—and for on-the-job experiences to come.
Complete the steps. They will provide you with another way of understanding the material as well as more information on how well you comprehend it.
Use the questions to assess your knowledge. Do not just read the chapter content; use the questions to find out what you know and what you do not. Study some more, review, and then assess your knowledge again.
Review the exam objectives. Develop your own questions and examples for each topic listed. If you can develop and answer several questions for each topic, you should not find it difficult to pass the exam.
Remember, the primary objective is not to pass the exam—it is to understand the material. After 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 CompTIA A+ certification program are designed to ensure that you have that solid foundation.
Exam-Taking Advice— Although this book is designed to prepare you to take and pass the Core Hardware Service Technician and Operating System Technologies exams, 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 using the PrepLogic test engine. This 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, answer it as best as you can; then mark it for review after you have finished the rest of the questions.
Good luck!
