Domain overview
Domain 3 of CompTIA A+ Core 1 220-1201 covers laptop hardware, mobile device connectivity, and mobile OS configuration. Expect scenario questions on touchpad and keyboard settings, display and battery replacement, Bluetooth and NFC pairing, hotspot and tethering setup, and locating power-hungry apps in Android and iOS settings.
Exam objectives
Touchpad palm rejection and sensitivity settings in Windows 11 Settings and vendor control panels
Enabling NFC and a default payment app for contactless mobile payments on Android and iOS
Configuring Bluetooth headset auto-connect and trusted device pairing on Windows tablets
Using Android battery usage screens and iOS Battery settings to find apps draining power
Assuming a driver update fixes erratic touchpad jumps; palm rejection or sensitivity settings are usually the actual fix.
Confusing NFC with Bluetooth for contactless payments; NFC must be enabled and a default payment app set.
Overlooking that Bluetooth auto-connect requires the headset to be paired and set as a trusted or preferred device.
