Frequently asked questions
Which CompTIA certification should I start with?
CompTIA A+ is the usual entry point for IT support and help-desk roles, and Network+ (N10-009) is the natural next step for anyone focused on networking. Both are vendor-neutral and require no prior certification.
How many exams does CompTIA A+ require?
Two. You must pass both Core 1 (220-1201) and Core 2 (220-1202); they are taken separately. Core 1 leans toward hardware, mobile devices, networking, virtualization and cloud, and hardware troubleshooting, while Core 2 focuses on operating systems, security, software troubleshooting, and operational procedures.
