Which enrollment method guarantees devices are automatically supervised?

The correct answer is Automated Device Enrollment, as it is specifically designed to ensure that devices are automatically supervised during the enrollment process. This method uses Apple's Device Enrollment Program (DEP), which allows devices to be purchased in bulk and registered directly with an Apple School Manager or Apple Business Manager account.

When a device is enrolled through this method, it is automatically associated with the specified Mobile Device Management (MDM) system and receives the supervisory status right from the start. This supervisory control provides enhanced management capabilities, including the ability to enforce security policies, remotely lock or wipe the device, and configure device settings without user intervention.

In contrast, the other methods either do not guarantee supervision or require additional steps to achieve it. Regular Enrollment and User Enrollment do not inherently provide supervision; they are typically user-initiated and offer limited control compared to supervised devices. Manual Enrollment necessitates user action as well and may involve more complexities in achieving the same level of control and capability that comes with Automated Device Enrollment.
