For Bring Your Own Device (BYOD) deployments, User Enrollment is the commonly used method. It allows users to enroll their personal devices in an MDM solution via a customized URL or portal, maintaining a separation between personal and managed data. Device Enrollment (option A) is typically for organization-owned devices, requiring more control than BYOD allows. Automated Device Enrollment (option C) is for organization-owned devices pre-registered with Apple, not BYOD. TheApple Platform Deployment Guidespecifies User Enrollment as the standard for BYOD.
