Correct Answer
Update the DPS enrollment's assigned IoT Hub and trigger the device to re-provision using the DPS reprovisioning policy
Why This Answer Is Correct
DPS supports reprovisioning policies that control what happens when a previously provisioned device re-registers. By updating the enrollment's target IoT Hub and configuring the reprovisioning policy (e.g., 'Reprovision and migrate data'), the device will receive new connection details pointing to the new hub at its next provisioning request.
This question evaluates your knowledge of Azure Device Provisioning Service — a core concept tested in Microsoft Certified: Azure IoT Developer Specialty (AZ-220). Understanding Azure Device Provisioning Service is essential for designing scalable, secure, and cost-effective cloud architectures. Mastery of this topic will help you answer scenario-based questions confidently on exam day.
You are manufacturing IoT devices that will be shipped globally and deployed in customer environments. You do not know which IoT Hub the device should connect to at manufacture time. You need zero-touch provisioning at customer deployment. Which service enables this?
You are using Azure DPS with X.509 certificate attestation. You need to provision all devices from the same manufacturer into a specific IoT Hub, while devices from a different manufacturer go to a different IoT Hub. How should you configure DPS?
You are using DPS with TPM attestation. A device's TPM chip fails and must be replaced. The replacement TPM has a different endorsement key. You need to re-provision the device to the same IoT Hub and preserve its device ID and twin data. What steps are required?
A developer is setting up an individual enrollment in Azure DPS using TPM attestation. What information must be obtained from the physical TPM chip on the device to register it?
You need to implement a dynamic allocation policy in DPS to assign devices to the nearest geographical IoT Hub based on a real-time lookup in a custom database. Which allocation policy should you configure?
