ACKNOWLEDGMENTS
From Mike Chapple:
This book marks the start of a new series of CertMike Test Prep books and I'd first like to thank the people who helped shape the vision for this series. The original idea was hatched over breakfast with two very supportive editors from the Wiley team: Ken Brown and Jim Minatel. I've worked with both Jim and Ken on many books over many years, and they're both insightful industry experts who know what it takes to produce a great book.
Mark Soper did the heavy lifting of putting this book together, and I am grateful to him for lending this series his expertise on end-user support and the A+ exams.
I'd also like to extend a special thank you to my agent, Carole Jelen of Waterside Productions. Carole is also an experienced industry pro who can deftly navigate the murky waters of publishing. Carole is the one who pushed me to create my own series.
Of course, the creation of any book involves a tremendous amount of effort from many people other than the authors. I truly appreciate the work of Adaobi Obi Tulton, the project editor. Adaobi and I have now worked together on many books, and she keeps the train on the tracks! I'd also like to thank Chris Crayton, the technical editor, who provided insightful advice and gave wonderful feedback throughout the book; and Magesh Elangovan, production editor, who guided me through layouts, formatting, and final cleanup to produce a great book. I would also like to thank the many behind-the-scenes contributors, including the graphics, production, and technical teams who make the book and companion materials into a finished product.
Finally, I would like to thank my family, who supported me through the late evenings, busy weekends, and long hours that a book like this requires to write, edit, and get to press.
From Mark Soper
My name is on the cover, but this book would not be a reality without the efforts of so many people behind the scenes. First, I want to thank CertMike, Mike Chapple, for the opportunity to work on this brand-new certification series. I am also deeply grateful to the editorial and production team at Wiley for all their hard work.
Many thanks to Ken Brown, acquisitions editor; Christine O'Connor, managing editor; Adaobi Obi Tulton, project editor; Chris Crayton, technical editor; Magesh Elangovan, production editor; Elizabeth Welch, copyeditor; and everyone else at Wiley who helped to make this book a reality.
I also want to thank my family for their support and for the many technology problems they've provided me with! It's been enjoyable to fix computer problems and to teach the next generation how things work. Thanks especially to my wife, Cheryl, for smiling and nodding as we've discussed tech issues during Christmas dinner.
Finally, thanks so much to Almighty God, who created everything visible and invisible, including the forces that make computers work, and for His great salvation.

INTRODUCTION
If you're preparing to take the A+ Core 2 exam, you might find yourself overwhelmed with information. This exam covers a very broad range of topics, and it's possible to spend weeks studying each one of them. Fortunately, that's not necessary!
As part of the CertMike Test Prep series, CompTIA A+ CertMike: Prepare. Practice. Pass the Test! Get Certified! Core 2 Exam 220-1102 is designed to help you focus on the specific knowledge that you'll need to pass the exam. CompTIA publishes a detailed list of exam objectives, and this book is organized around those objectives. Each chapter clearly states the single objective that it covers and then, in a few pages, covers the material you need to know about that objective.
You'll find two important things at the end of each chapter: Exam Essentials and Practice Questions. The CertMike Exam Essentials distill the major points from the chapter into just a few bullet points. Reviewing the Exam Essentials is a great way to prepare yourself right before the exam. Mike also recorded a free audio version of the Exam Essentials that you'll find on the book's companion website at www.wiley.com/go/sybextestprep. They're great listening when you're in the car, at the gym, or mowing the lawn!
Each chapter concludes with two Practice Questions that are designed to give you a taste of what it's like to take the exam. You'll find that they're written in the same style as the A+ exam questions and have detailed explanations to help you understand the correct answer. Be sure to take your time and thoroughly read these questions.
Finally, the book's website includes a full-length practice exam that you can use to assess your knowledge when you're ready to take the test. Good luck on the A+ Core 2 exam!
NOTE
Don't just study the questions and answers! The questions on the actual exam will be different from the Practice Questions included in this book. The exam is designed to test your knowledge of a concept or objective, so use this book to learn the objectives behind the questions.
THE A+ PROGRAM
A+ is designed to be a vendor-neutral certification for those seeking to enter the information technology field. CompTIA recommends this certification for individuals who want to be problem solvers in the world of endpoint management and technical support. Common job roles held by A+ certified individuals include the following:
Helpdesk technician
Field service technician
Associate network engineer
Junior systems administrator
Desktop support specialist
System support technician
The A+ certification is unique in that earning it requires passing two separate exams:
A+ Core 1
(
220-1101)
, which covers mobile devices, networking technology, hardware, virtualization, and cloud computing
A+ Core 2 (220-1102)
, which covers operating systems, security, software, and operational procedures
This book focuses on the Core 2 exam, which covers four major domains of knowledge:
Operating Systems
Security
Software Troubleshooting
Operational Procedures
These four areas include a range of topics, from configuring operating system settings to preventing malware attacks, while focusing heavily on the basic knowledge expected of IT technicians.
The A+ exam uses a combination of standard multiple-choice questions and performance-based questions that require you to manipulate objects on the screen. This exam is designed to be straightforward and not to trick you. If you know the material in this book, you will pass the exam.
Each exam costs $239 in the United States, with roughly equivalent prices in other locations around the globe. You can find more details about the A+ exams and how to take it at:
www.comptia.org/certifications/a#examdetails
You'll have 90 minutes to take the exam and will be asked to answer up to 90 questions during that time period. Your exam will be scored on a scale ranging from 100 to 900, with a passing score of 700.
NOTE
CompTIA frequently does what is called item seeding, which is the practice of including unscored questions on exams. It does so to gather psychometric data, which is then used when developing new versions of the exam. Before you take the exam, you will be told that your exam may include these unscored questions. So, if you come across a question that does not appear to map to any of the exam objectives—or for that matter, does not appear to belong in the exam—it is likely a seeded question. You never really know whether or not a question is seeded, however, so always make your best effort to answer every question.
Taking the Exam
Once you are fully prepared to take the exam, you can visit the CompTIA website to purchase your exam voucher:
https://store.comptia.org
Currently, CompTIA offers two options for taking the exam: an in-person exam at a testing center and an at-home exam that you take on your own computer.
TIP
This book includes a coupon that you may use to save 10 percent on your CompTIA exam registration.
In-Person Exams
CompTIA partners with Pearson VUE's testing centers, so your next step will be to locate a testing center near you. In the United States, you can do this based on your address or your zip code, while non-U.S. test takers may find it easier to enter their city and country. You can search for a test center near you at the Pearson Vue website, where you will need to navigate to “Find a test center.”
www.pearsonvue.com/comptia
Now that you know where you'd like to take the exam, simply set up a Pearson VUE testing account and schedule an exam on their site.
On the day of the test, take two forms of identification, and be sure to show up with plenty of time before the exam starts. Remember that you will not be able to take your notes, electronic devices (including smartphones and watches), or other materials in with you.
At-Home Exams
CompTIA began offering online exam proctoring in 2020 in response to the coronavirus pandemic. As of this writing, the at-home testing option was still available and appears likely to continue. Candidates using this approach will take the exam at their home or office and be proctored over a webcam by a remote proctor.
Due to the rapidly changing nature of the at-home testing experience, candidates wishing to pursue this option should check the CompTIA website for the latest details.
After the Exam
Once you have taken the exam, you will be notified of your score immediately, so you'll know if you passed the test right away. You should keep track of your score report with your exam registration records and the email address you used to register for the exam.
After you earn the A+ certification, you're required to renew your certification every three years by either earning an advanced certification, completing a CertMaster continuing education program, or earning 20 continuing education units over a three-year period.
Many people who earn the A+ credential use it as a stepping stone to earning other certifications in their areas of interest. Those interested in networking work toward the Network+ credential, data analytics professionals might go on to earn the Data+ certification, and the Security+ program is a gateway to a career in cybersecurity.

CORE 1 EXAM 220-1102 EXAM OBJECTIVES
CompTIA goes to great lengths to ensure that its certification programs accurately reflect the IT industry's best practices. They do this by establishing committees for each of its exam programs. Each committee consists of a small group of IT professionals, training providers, and publishers who are responsible for establishing the exam's baseline competency level and who determine the appropriate target-audience level.
Once these factors are determined, CompTIA shares this information with a group of hand-selected subject matter experts (SMEs). These folks are the true brainpower behind the certification program. The SMEs review the committee's findings, refine them, and shape them into the objectives that follow this section. CompTIA calls this process a job-task analysis.
Finally, CompTIA conducts a survey to ensure that the objectives and weightings truly reflect job requirements. Only then can the SMEs go to work writing the hundreds of questions needed for the exam. Even so, they have to go back to the drawing board for further refinements in many cases before the exam is ready to go live in its final state. Rest assured that the content you're about to learn will serve you long after you take the exam.
CompTIA also publishes relative weightings for each of the exam's objectives. The following table lists the four A+ Core 2 objective domains and the extent to which they are represented on the exam.
NOTE
The A+ exam covers both Windows 10 and 11. You should be familiar with how the information in these objectives applies to both operating systems.
