Introduction
Welcome to CompTIA A+ Practice Questions Exam Cram. The sole purpose of
this book is to provide you with practice questions that are complete with
answers and explanations to help you learn, drill, and review for the CompTIA
A+ certification exam. The book offers many questions that will help you practice
each exam objective and will help you assess your knowledge before you
write the real exam. The detailed answers to every question will help you reinforce
your knowledge about different issues involving the concepts associated
with the updated A+ exam (2009 Edition), which also includes topics on
Windows 7 and IPv6.
Who This Book Is For
If you have studied the content for both the 220-701 and 220-702 exam and feel
you are ready to put your knowledge to the test, but you are not sure that you
want to take the real exam yet, this book is for you! If you have answered other
practice questions or unsuccessfully taken the real exam, and want to do more
practice questions before going to take the real exam, this book is for you, too!
Even when the exam is done and you have passed with flying colors and have the
A+ certificate in your pocket, keep the book handy on your desktop to look for
answers to your everyday security issues.
What You Will Find in This Book
This book is all about practice questions! The practice questions in the book,
some very easy and others with a little complicated problem scenario, all are
intended to raise your confidence level before you take the real exam. You will
find questions that you will face in real life.
This book is organized according to the objectives published by CompTIA for
the 220-701: CompTIA A+ Essentials and 220-702: CompTIA A+ (2009
Edition) exams. Each chapter corresponds to an exam objective, and in every
chapter, you will find the following three elements:
. Practice Questions: These are the numerous questions that will help
you learn, drill, and review exam objectives. All of the questions in this
section are multiple-choice type. Choose the correct answer based on
your knowledge of security.
. Quick-Check Answer Key: After you have finished answering the questions,
you can quickly grade your exam from this section. Only correct

CompTIA A+ 220-701 and 220-701 Practice Questions Exam Cram
answers are given in this section. No explanations are offered yet! Even if
you have answered a question incorrectly, do not be discouraged. Just
move on! Keep in mind that this is not the real exam. You can always
review the topic and do the questions again.
. Answers and Explanations: This section provides you with correct
answers as well as further explanations about the content posed in that
question. Use this information to learn why an answer is correct and to
reinforce the content in your mind for the exam day.
Note
It is not possible to reflect a real exam on a paper product. As mentioned earlier, the purpose
of the book is to help you prepare for the exam and not provide you with real exam
questions. Neither the author nor the publisher can guarantee that you will pass the exam
only by memorizing the practice questions given in this book.

Hints for Using This Book
Because this book is a paper practice product, you might want to complete your
exams on a separate piece of paper so that you can reuse the practice questions
again and again without having previous answers in your way. Also, a general
rule of thumb across all practice questions products is to make sure that you are
scoring in the high 80% to 90% range for all topics before attempting the real
exam. The higher percentages you score on practice question products, the better
your chances for passing the real exam. Of course, we cannot guarantee a
passing score on the real exam, but we can offer you plenty of opportunities to
practice and assess your knowledge level before you enter the real exam.
When you have completed the exam on paper, use the companion CD to take a
timed exam. This will further help you gain confidence and make a self-assessment
in case you need more study. Your results will indicate the exam objectives
in which you need further study or hands-on practice.
Need Further Study?
Are you having a hard time correctly answering these questions? If so, you probably
need further review of all exam objectives. Be sure to see the following sister

Hardware
The first domain for the A+ Essentials (220-701) exam is hardware, which
focuses on teaching you to identify components and to demonstrate a basic
knowledge of hardware technology. This domain is essential because it gives
you a background for the other domains and also counts as 27% of the test
score, the largest percentage of all the domains. It also includes the most
objectives because today’s PCs have such a wide variety of hardware and
technology:
The objectives for this domain are as follows:
. 1.1—Categorize storage devices and backup media
. 1.2—Explain motherboard components, types, and features
. 1.3—Classify power supplies types and characteristics
. 1.4—Explain the purpose and characteristics of CPUs and their features
. 1.5—Explain cooling methods and devices
. 1.6—Compare and contrast memory types, characteristics, and their
purpose
. 1.7—Distinguish between the different display devices and their
characteristics
. 1.8—Install and configure peripherals and input devices
. 1.9—Summarize the function and types of adapter cards
. 1.10—Install, configure, and optimize laptop components and features
1.1 Categorize storage devices and backup media
. FDD
. HDD
. Solid state vs. magnetic
. Optical drives
. CD/DVD/RW/Blu-Ray
. Removable storage
. Tape drive
. Solid state (e.g., thumb drive, flash, SD cards, USB)
. External CD-RW and hard drive
. Hot swappable devices and non-hot swappable devices From <
