Automated Device Enrollment (ADE) is ideal for distributing devices to multiple users across multiple regions because it allows enrollment in an MDM solution without physically handling the devices. Devices are pre-registered in Apple Business Manager or Apple School Manager, and upon setup, they automatically enroll in MDM, streamlining deployment at scale. Device Enrollment (option A) requires manual profile installation, impractical for large, dispersed deployments. User Enrollment (option B) is suited for BYOD, not organization-owned devices distributed widely. TheApple Platform Deployment Guiderecommends ADE for such scenarios.
