Before diving into your CompTIA A+ Study Guide , it's essential to have a solid understanding of the CompTIA A+ exam structure. The certification is divided into two exams: Core 1 (220-1101) and Core 2 (220-1102). Core 1 focuses on hardware, networking technology, mobile devices, and cloud computing, while Core 2 covers operating systems, security, software troubleshooting, and operational procedures. Knowing the structure will help you align your study efforts with the exam objectives, ensuring that you're covering all necessary content.
