Introduction
The A+ certification program was developed by the Computing Technology Industry
Association (CompTIA) to provide an industry-wide means of certifying the competency of
computer service technicians. The A+ certification is granted to those who have attained the
level of knowledge and troubleshooting skills that are needed to provide capable support in
the field of personal computers. CompTIA is a widely respected industry leader in this area.
CompTIA’s A+ exam objectives are periodically updated to keep the certification appli-
cable to the most recent hardware and software. This is necessary because a technician must
be able to work on the latest equipment. The most recent revisions to the objectives—and to
the whole program—were introduced in 2022 and are reflected in this book.
This book and the Sybex CompTIA A+ Complete Study Guide (both the Standard and
Deluxe Editions) are tools to help you prepare for this certification—and for the new areas
of focus of a modern computer technician’s job.
What Is A+ Certification?
The A+ certification program was created to offer a wide-ranging certification, in the sense
that it’s intended to certify competence with personal computers from many different
makers/vendors. Everyone must take and pass two exams: 220-1101 and 220-1102.
You don’t have to take the 220-1101 exam and the 220-1102 exam at the same time. The
A+ certification isn’t awarded until you’ve passed both tests. For the latest pricing on the
exams and updates to the registration procedures, call Pearson VUE at (877) 551-7587. You
can also go to Pearson VUE for additional information or to register online at www
.pearsonvue.com/comptia. If you have further questions about the scope of the exams or
related CompTIA programs, refer to the CompTIA website at www.comptia.org.
Who Should Buy This Book?
If you want to acquire a solid foundation in personal computer basics and your goal is to
prepare for the exams by filling in any gaps in your knowledge, this book is for you. You’ll
find clear explanations of the concepts you need to grasp and plenty of help to achieve the
high level of professional competency you need to succeed in your chosen field.
If you want to become certified as an A+ holder, this book is definitely what you need.
However, if you just want to attempt to pass the exam without really understanding the
basics of personal computers, this guide isn’t for you. It’s written for people who want to
acquire skills and knowledge of personal computer basics.

Tips for Taking the A+ Exams
Here are some general tips for taking your exams successfully:
■ Bring two forms of ID with you. One must be a photo ID, such as a driver’s license. The
other can be a major credit card or a passport. Both forms must include a signature.
■ Arrive early at the exam center so that you can relax and review your study materials,
particularly tables and lists of exam-related information.
■ Read the questions carefully. Don’t be tempted to jump to an early conclusion. Make
sure you know exactly what the question is asking.
■ Don’t leave any unanswered questions. Unanswered questions are scored against you.
■ There will be questions with multiple correct responses. When there is more than one
correct answer, a message at the bottom of the screen will prompt you to either “Choose
two” or “Choose all that apply.” Be sure to read the messages displayed to know how
many correct answers you must choose.
■ When answering multiple-choice questions you’re not sure about, use a process of elim-
ination to get rid of the obviously incorrect answers first. Doing so will improve your
odds if you need to make an educated guess.
■ On form-based tests (nonadaptive), because the hard questions will eat up the most
time, save them for last. You can move forward and backward through the exam.
■ For the latest pricing on the exams and updates to the registration procedures, visit
CompTIA’s website at www.comptia.org.
CompTIA A+ 1100 Series Exam
Objectives
CompTIA goes to great lengths to ensure that its certification programs accurately reflect the
IT industry’s best practices. The company does this by establishing Cornerstone 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. They review the committee’s findings, refine them, and shape them
into the objectives you see before you. CompTIA calls this process a job task analysis (JTA).
Finally, CompTIA conducts a survey to ensure that the objectives and weightings truly
reflect the job requirements. Only then can the SMEs go to work writing the hundreds of
questions needed for the exam. And, in many cases, they have to go back to the drawing
