CompTIA 220-1001 Exam

Notice

If you get a question wrong, you can still click on the other answers. This will open up hints and explanations (if available), which will provide additional information. Exam should be 1 minute per question and please time accordingly.

The two cores of A+ exams are very smiliar and the knowlagebase is linked across both exams. I highly recommend that you go through the questions for both core 1 and core 2 compeltely at least once before talking either exam. Then you can you back and study the questions intricately for one of the two cores before taking that specific section exam.
