A+ Practice Questions for the Comptia A+ Exam 220-901

Introduction 

The process of answering a test question is our ultimate test of knowledge. After hours of video watching, book reading, and note taking, do you really know the material? If you're trying to prove yourself, nothing beats getting the right answer. In 2009, I started an email list that would send subscribers a single CompTIA A+ sample exam question each day. I had no idea if there would be an interest in this list, but my daily Pop Quiz quickly gained in popularity. Today, tens of thousands of people try to answer my daily question, and I now write hundreds of Pop Quiz questions a year. This blog is a combination of my daily pop quiz questions, hundreds of new questions, and newly written performance-based questions. I've personally curated every question to validate its applicability to the 220-901 exam objectives, and many of the original Pop Quiz questions have been updated to make the questions and answers as unambiguous as possible. I hope this book will help you be the smartest one in the room. 

Best of luck with your studies!
