Introduction
Welcome to CompTIA A+ Practice Questions Core 1 (220-1101) and Core 2 (220-
1102) Exam Cram. The 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 exams. The book offers 480
questions that help you practice each exam domain and help you assess your
knowledge before you take the real exams. The detailed answers to every ques-
tion aid in reinforcing your knowledge about the concepts associated with the
CompTIA A+ exams.
Who This Book Is For
The CompTIA A+ exams are designed for individuals with at least 12 months
of hands-on experience in a lab or in the field. If you have that experience, this
book will be an excellent late-stage study tool. However, if you have not acquired
that experience, I recommend that you register for a hands-on A+ course or, at
the very least, purchase an A+ study guide such as the CompTIA A+ Core 1
220-1101 and Core 2 220-1102 Exam Cram textbook or consider my CompTIA
A+ 220-1101 Complete Video Course and CompTIA A+ 220-1102 Complete Video
Course. After you take the course and/or read the study guide, return to this book
as your late-stage test preparation to be used just before taking the real exams.
What You Will Find in This Book
In every chapter devoted to practice exams, you will find the following three
elements:
▶ Practice Questions: Each chapter includes 80 questions that help you
learn, drill, and review for the exams.
▶ Quick-Check Answer Key: After you finish answering the questions,
you can quickly grade your exam from this section. Only correct answers
are given in this section. No explanations are offered yet. Even if you
answered a question incorrectly, do not be discouraged. Keep in mind that
this is not the real exam. You can always review the topic and revisit the
questions again.

▶ Answers and Explanations: This section provides you with correct
answers as well as 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 exam day.
The book also comes with a companion website. It contains a simulated testing
environment where you can take all the exams on a computer in study mode or
in full practice test mode. It also includes two bonus exams. Create an account
and register this book at http://www.pearsonitcertification.com to get access to
the bonus content. For those who purchased a Kindle edition from Amazon, the
access code will be supplied directly by Amazon.
Hints for Using This Book
Complete your exams on a separate piece of paper so that you can reuse the
practice questions if necessary. Also, plan to score 90% or higher on each exam
before moving on to the next one. The higher you score on these practice ques-
tions, the better your chances for passing the real exams.

Customizing Your Exams
Once you are in the exam settings screen, you can choose to take exams in one
of three modes:
▶ Study mode: This mode allows you to fully customize your exams and
review answers as you are taking an exam. This is typically the mode you
would use first to assess your knowledge and identify information gaps.
▶ Practice Exam mode: This mode locks certain customization options in
order to present a realistic exam experience. Use this mode when you are
preparing to test your exam readiness.
▶ Flash Card mode: This mode strips out the answers and presents you
with only the question stem. This mode is great for late-stage preparation,
when you really want to challenge yourself to provide answers without the
benefit of seeing multiple-choice options. This mode does not provide the
detailed score reports that the other two modes provide, so it is not the
best mode for helping you identify knowledge gaps.
In addition to these three modes, you will be able to select the source of your
questions. You can choose to take exams that cover all of the chapters, or you
can narrow your selection to just a single chapter or the chapters that make up
specific parts in the book. All chapters are selected by default. If you want to nar-
row your focus to individual chapters, simply deselect all the chapters and then
select only those on which you wish to focus in the Objectives area.
You can also select the exam banks on which to focus. Each exam bank comes
complete with a full exam of questions that cover topics in every chapter. The
exams printed in the book are available to you, as are two additional exams of
unique questions. You can have the test engine serve up exams from all banks
or just from one individual bank by selecting the desired banks in the exam
bank area.
There are several other customizations you can make to your exam from the
exam settings screen, such as the time allowed for taking the exam, the number
of questions served up, whether to randomize questions and answers, whether to
show the number of correct answers for multiple-answer questions, and whether
to serve up only specific types of questions. You can also create custom test banks
by selecting only questions that you have marked or questions on which you
have added notes.

Updating Your Exams
If you are using the online version of the Pearson Test Prep software, you should
always have access to the latest version of the software as well as the exam data.
If you are using the Windows desktop version, every time you launch the soft-
ware, it will check to see if there are any updates to your exam data and auto-
matically download any changes made since the last time you used the software.
This requires that you be connected to the Internet at the time you launch the
software.
Sometimes, due to a number of factors, the exam data might not fully download
when you activate your exam. If you find that figures or exhibits are missing,
you might need to manually update your exams. To update a particular exam you
have already activated and downloaded, simply select the Tools tab and click the
Update Products button. Again, this is only an issue with the desktop Windows
application.
If you wish to check for updates to the Windows desktop version of the Pearson
Test Prep exam engine software, simply select the Tools tab and click the Update
Application button. Doing so allows you to ensure that you are running the lat-
est version of the software engine.

Chances are that when you take the real CompTIA exam, the questions will be
based on these percentages, but you never know. The questions are chosen at
random, so you have to be prepared for anything and study all of the objectives.
Each domain has several objectives. There are far too many to list in this book, but
I recommend that you download a copy of the objectives for yourself. You can get
them from CompTIA’s A+ web page (https://www.comptia.org/certifications/a),
and I link to them at my website (https://dprocomputer.com) as well.
Let’s talk about each domain briefly.
Domain 1.0: Mobile Devices (15%)
CompTIA refers to any portable computers as mobile devices, including lap-
tops, tablets, smartphones, and hybrid versions of those devices. This domain
comprises only 15% of the exam, but remember that every domain is important.
You should be able to demonstrate the ability to install and configure laptop
hardware and software. You also should know how to operate laptops’ special
functions, such as dual displays, wireless, and Bluetooth. Finally, because of the
explosion of mobile devices in the tech world and the increased adoption of
bring your own device (BYOD) policies by companies, you need to understand
the hardware side of smartphones and tablets for the 220-1101 exam.
Domain 2.0: Networking (20%)
The Networking domain covers network standards, cabling, connectors, and
tools. TCP/IP is also a big topic in this domain; you will undoubtedly see ques-
tions on IP addresses, ports, and protocols. You should be able to install and
configure a basic wired or wireless SOHO network and use the appropriate net-
working tools. Plus, you should be able to describe the various types of servers
and networking hardware available.
Domain 3.0: Hardware (25%)
The Hardware domain concerns building, upgrading, and maintaining a com-
puter. The motherboard, CPU, and RAM are the guts of a desktop computer, so
to speak. They are installed inside a computer case.
You are required to understand motherboard form factors and compatibility
concerns as well as the ports, connectors, and expansion slots of a motherboard.
You should also know how to access, configure, and update the BIOS/UEFI and
understand the relationship between the BIOS/UEFI, CMOS, and lithium battery.

Introduction to the 220-1101 Exam 3
The BIOS/UEFI is also known as UEFI/BIOS, or just BIOS or UEFI. You might see any of
these terms on the A+ exams or in the IT field. Remember that the UEFI is a newer tech-
nology that augments the BIOS and allows for more security and better communication
with the operating system.
NOTE
Then there’s everything that connects to the motherboard: CPU and fan, RAM,
expansion cards, and storage drives. Plus, there are all of the ports on a com-
puter, such as USB, video, and audio ports. Finally, you should know peripherals
such as monitors, printers, USB flash drives, and other devices that interact with
the computer.
Domain 4.0: Virtualization and Cloud
Computing (11%)
The Virtualization and Cloud Computing domain is new to the A+ Core 1 (220-
1101) exam. Coming in at 11% of the exam—but still quite important—this domain
summarizes cloud-computing concepts such as common cloud models, cloud char-
acteristics, and desktop virtualization. It also covers the purpose of virtual machines
(VMs) and resource and security requirements. If you are not using VMs now, you
will be. And chances are that you already make use of some type of cloud-based ser-
vices. This domain is considered to be an introduction to the cloud, but you should
study it carefully because you will be dealing with the cloud and VMs often.
Domain 5.0: Hardware and Network
Troubleshooting (29%)
Troubleshooting is key; it is the most vital ability a technician should possess.
You need to understand how to troubleshoot hardware failures, bootup issues,
no-display obstacles, network connectivity difficulties, and, of course, printing
problems. This is the crux of the exam (both A+ exams, to be accurate), and you
need to study and practice accordingly.
Expect one question out of four (or more) to be based on a troubleshooting
scenario. Practice the questions in this book, understand the concepts, and—
importantly—practice the topics on real computers in a hands-on way when-
ever possible. Hands-on experience plays a big role in troubleshooting, and
CompTIA recommends that a test-taker have 12 months of hands-on experi-
ence in the lab or field.

4 Chapter 1
Remember this: Troubleshooting is a huge portion of what you do as a computer
technician. To increase your job security, you need to be a good troubleshooter.
Today’s CompTIA A+ exams reflect this concept by incorporating many para-
graph-based, scenario-oriented troubleshooting questions. You need to imagine
yourself in the situation and think carefully about how to fix the problem. One
thing that can aid you in this process is the CompTIA A+ six-step troubleshoot-
ing process. Memorize it!
Step 1. Identify the problem.
▶ Gather information from the user, identify user changes, and, if
applicable, perform backups before making changes.
▶ Inquire regarding environmental or infrastructure changes.
Step 2. Establish a theory of probable cause. (Question the obvious.)
▶ If necessary, conduct external or internal research based on
symptoms.
Step 3. Test the theory to determine the cause.
▶ Once the theory is confirmed, determine the next steps to
resolve the problem.
▶ If the theory is not confirmed, establish a new theory or esca-
late.
Step 4. Establish a plan of action to resolve the problem and imple-
ment the solution.
▶ Refer to the vendor’s instructions for guidance.
Step 5. Verify full system functionality and, if applicable, implement
preventative measures.
Step 6. Document the findings, actions, and outcomes.
Always consider corporate policies, procedures, and impacts before implementing changes.
NOTE
I really can’t stress enough the importance of this domain. Practice on real sys-
tems and be ready to troubleshoot!

Introduction to the 220-1101 Exam 5
Test-Taking Tips
My first recommendation is to take the exams slowly. Don’t rush through, espe-
cially on the first exam. Carefully read each question. Some questions are tricky
by design. Others may seem tricky if you lack knowledge in certain areas. Still
other questions are somewhat vague, and that is intentional as well. You need to
place yourself in the scenario of the question. Think of yourself actually install-
ing a CPU and heat sink, or imagine that you are upgrading a video card. Picture
in your head the steps you must take to accomplish what the question is asking
of you. Envision what you do with computers step by step, and the answers will
come more easily to you.
Next, read through all of the answers. Don’t just jump on the first one that
seems correct to you. Look at each answer and ask yourself whether it is right
or wrong. And if it is wrong, define why it is wrong. Using this approach helps
you eliminate wrong answers in the search for the correct answer. When you
have selected an answer, be confident in your decision.
Finally, don’t get stuck on any one question. You can always mark it and return
to it later. This advice especially applies to performance-based questions and
longer questions. I offer more tips as we progress through the book, and I sum-
marize all test-taking tips at the end of this book.
Getting Ready for the Practice
Exams
The next three chapters feature practice exams based on the 220-1101 exam.
Every exam is followed by in-depth explanations. Be sure to read them carefully.
Don’t move on to another exam until you understand the first one. By that I
mean you should be scoring 90% or higher on the exam (without memorizing
the answers). Really understand the concepts before moving on to another exam.
This makes you an efficient test-taker and allows you to benefit the most from
this book.
Consider timing yourself. Give yourself 90 minutes to complete each exam.
Write down your answers on a piece of paper. When you are finished, if there is
still time left, review your answers for accuracy.
Each exam is more difficult than the one before it. Don’t get overconfident if
you do well on the first exam; your skills will be tested more thoroughly as you
progress. And don’t get too concerned if you don’t score 90% on the first try.

This just means you need to study more and try the test again later. Keep study-
ing and practicing!
After each exam is an answer key, followed by in-depth answers/explanations.
Don’t skip the explanations, even if you think you know the concept. I often
insert little tidbits of knowledge that are on the periphery of the concept; these
tidbits help you build a stronger foundation of knowledge in general. In other
words, I might branch off the main topic in order to give you a clearer, bigger
picture of the 220-1101 exam and of the tech world in general.
So take a deep breath, and let’s go!
