CompTIA A+ exam guide: the two-exam format, domains, cost, and a free practice quiz covering hardware, networking, operating systems, security, and troubleshooting.
CompTIA A+ is the industry-standard entry point into IT. It validates the practical skills to support and troubleshoot hardware, operating systems, networks, and security — the core of any help-desk or technician role.
A+ requires passing two exams: Core 1 (220-1101) and Core 2 (220-1102). Together they cover the breadth an entry-level IT professional needs.
