Free online course CompTIA A Core 1 Exam Prep Training Course

About the free online course

Step into IT support with confidence by preparing for the CompTIA A+ Core 1 (220-1101) exam through a focused, practical learning experience designed for real-world troubleshooting. This free online course helps you build the foundations employers expect from entry-level technicians, while also giving you a clear roadmap for how to approach the A+ exams and avoid common study pitfalls.

You will strengthen your understanding of modern device hardware, including laptops, mobile devices, displays, accessories, and connectivity options used in day-to-day support. At the same time, you’ll build solid networking fundamentals: how IP addressing works, what common ports do, how devices and services fit together, and how to make sense of DNS, DHCP, VLANs, VPNs, wireless standards, and typical connection types. These skills translate directly to help desk tickets and hands-on environments where diagnosing the simplest detail often resolves the biggest problem.

Beyond core hardware and networking, the course also reinforces the tools and connectors technicians use, from Ethernet termination and cabling types to fiber, adapters, and peripheral interfaces. You’ll gain clarity around memory, storage technologies, motherboard compatibility, power considerations, and everyday maintenance scenarios. Printers and multifunction devices are also addressed from a support perspective, so you can recognize symptoms, perform appropriate maintenance, and identify likely failing components without guesswork.

Because modern support roles increasingly touch cloud and virtualization concepts, you’ll also get introduced to cloud models and key characteristics, plus the basics of client-side virtualization. Throughout the learning path, practice-style questions help you think like the exam: selecting the best next step, interpreting symptoms, and applying a consistent troubleshooting methodology. By the end, you’ll be better prepared not only to pass Core 1, but to communicate clearly, work methodically, and solve problems efficiently in an IT support or junior technician role.
