Introduction
Welcome to CompTIA A+ Core 1 (220-1001) and Core 2 (220-1002) 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 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 question aid in reinforcing your knowledge about the concepts associated with the 1000 series of 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 the lab or 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 220-1001 and Core 220-1002 Exam Cram textbook or consider my A+ 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: There are 480 questions that help you learn, drill, and review for the exams. All of the questions in this section are multiple choice.
▶ 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 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 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 a “Real-World Scenarios” document and supporting performance-based exercises and videos, as well as two bonus exams. Create an account and register this book at http://www.pearsonitcertification.com/ to get access to the bonus content. (Access to the test engine is print version only.)
Hints for Using This Book
Complete your exams on a separate piece of paper so that you can reuse the practice questions again if necessary. Also, plan to score 90 percent or higher on each exam before moving on to the next one. The higher you score on these practice questions, the better your chances for passing the real exams.
I am available for questions at my website: https://dprocomputer.com
I answer questions Monday through Friday, usually in the mornings.

Customizing Your Exams
Once you are in the exam settings screen, you can choose to take exams in one of three modes:
▶ Study mode: Allows you to fully customize your exams and review answers as you are taking the exam. This is typically the mode you would use first to assess your knowledge and identify information gaps.
▶ Practice Exam mode: Locks certain customization options, as it is presenting a realistic exam experience. Use this mode when you are preparing to test your exam readiness.
▶ Flash Card 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 do, so you should not use it if you are trying to 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 narrow 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 two exams printed in the book are available to you as well as two additional exams of unique questions. You can have the test engine serve up exams from all four 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 of 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.
CompTIA A+ Practice Questions Exam Cram Core 1 (220-1001) and Core 2 (220-1002)
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 software while connected to the Internet, it checks whether there are any updates to your exam data and automatically downloads any changes that were made since the last time you used the software.
Sometimes, due to many factors, the exam data may not fully download when you activate your exam. If you find that figures or exhibits are missing, you may need to manually update your exams. To update a particular exam you have already activated and downloaded, simply click 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 Pearson Test Prep exam engine software, Windows desktop version, simply click the Tools tab and click the Update Application button. Taking this step ensures that you are running the latest version of the software engine.

Each domain has several objectives. There are far too many to list in this book, but I recommend you download a copy of the objectives for yourself. You can get them from CompTIA’s A+ web page or from my website: https://dprocomputer.com.
Let’s talk about each domain briefly.
Domain 1.0: Mobile Devices (14%)
CompTIA refers to any portable computers as mobile devices, including laptops, tablets, smartphones, and hybrid versions of those devices. This domain comprises only 14 percent 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 220-1001 exam.
Domain 2.0: Networking (20%)
The Networking domain covers network standards, cabling, connectors, and tools. TCP/IP is also a big portion of this domain; you will undoubtedly see questions 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 networking tools. Plus, you should be able to describe the various types of servers and networking hardware available.
Domain 3.0: Hardware (27%)
The Hardware domain concerns building a computer and upgrading it. The core of a desktop computer includes the motherboard, CPU, and RAM. Those are the guts of the 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, buses, and expansion slots of a motherboard. You should also know how to access, configure, and update the BIOS and understand the relationship between the BIOS, CMOS, and lithium battery.
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 that concept by incorporating many paragraph-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 troubleshooting process. Memorize it!
Step 1. Identify the problem.
Step 2. Establish a theory of probable cause. (Question the obvious.)
Step 3. Test the theory to determine cause.
Step 4. Establish a plan of action to resolve the problem and implement the solution.
Step 5. Verify full system functionality and, if applicable, implement preventative measures.
Step 6. Document findings, actions, and outcomes.
I really can’t stress enough the importance of this domain. Practice on real systems and be ready to troubleshoot!
Test-Taking Tips
My first recommendation is to take the exams slowly. Don’t rush through, especially 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 installing 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 summarize 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 220-1001 exam. Every exam is followed by in-depth explanations. Be sure to read them carefully. Don’t move on to another exam until you have mastered the first one. And by “mastered,” I mean you should be scoring 90 percent 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 gets progressively more difficult. 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 percent on the first try. This just means you need to study more and try the test again later. Keep studying and practicing!
After each exam is an answer key, followed by the 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 serve to build you a stronger foundation of knowledge in general. In other words, I might branch off the main topic, but this is done so you can get a clearer, bigger picture of the 220-1001 exam and of the tech world in general.
So take a deep breath, and let’s go!
