The CompTIA A+ Core 1 220-1201 exam focuses on mobile devices, networking, hardware, virtualization and cloud computing, and hardware and network troubleshooting. Core 1 is one exam in the A+ path; full CompTIA A+ certification also requires Core 2.
Mobile Devices covers laptops, tablets, smartphones, accessories, wireless settings, and mobile connectivity. Study how technicians identify device components, connect peripherals, recognize battery or display symptoms, and choose the most practical first troubleshooting step for portable systems.
Networking focuses on ports, protocols, cabling, wireless standards, IP addressing, DHCP, DNS, and basic network tools. Core 1 expects recognition of how devices connect, how addressing works, and which network setting or physical connection best matches a support scenario.
Hardware includes motherboards, CPUs, memory, storage, power, printers, displays, connectors, and common peripherals. The exam often asks which component fits a requirement, which part explains a symptom, or which replacement or compatibility concern a technician should notice first.
Virtualization and Cloud Computing covers virtual machines, hypervisors, hosted resources, and basic cloud service ideas. Hardware and Network Troubleshooting is equally important: study symptoms, probable causes, safe first actions, printer issues, connectivity failures, and how to verify a fix.
