What this objective tests

220-1101 Mobile Devices — Key Topics

Mobile devices questions test connection types (cellular, Wi-Fi, Bluetooth, NFC), synchronisation, common symptoms and mobile OS management basics.

Connection types: cellular (4G/5G), Wi-Fi, Bluetooth, NFC, USB, hotspot.
Mobile OS management: MDM, MAM, corporate vs personal data separation.
Common symptoms: battery drain, overheating, connectivity, slow performance.
Synchronisation methods and data backup for iOS and Android.

Common exam traps

Where candidates lose marks on Mobile Devices

⚠NFC requires very close proximity (a few centimetres) to function.
⚠Airplane mode disables cellular, Wi-Fi AND Bluetooth by default.
⚠MDM manages the whole device; MAM manages only the corporate apps.
⚠A factory reset solves software issues but wipes all user data.
