CompTIA A+ 220-801 Practice Exam

This is a complete, 100 question practice exam for the CompTIA A+ 220-801 certification, including detailed answers.
This chapter is from the book

Now let’s kick it up a notch. This second 220-801 exam could be considered an intermediate practice test. I’ll be mixing in some more difficult questions this time. Unlike the first exam, this one is freestyle, meaning the questions are randomized. You can expect questions from any of the domains, in any order.

Again, the goal here is to make sure you understand all of the concepts before moving on to the next test. If you didn’t already, I suggest taking a break between exams. If you just completed the first exam, give yourself a half-hour or so before you begin this one. If you didn’t score 90% or higher on Exam A, go back and study; then retake Exam A until you pass with 90% or higher.

Write down your answers and check them against the answer key that immediately follows the exam. After the answer key, you will find explanations for all of the answers. Good luck!
