You have an Azure IoT hub that uses a Device Provisioning Service instance.
You create a new individual device enrollment that uses symmetric key attestation.
Which detail from the enrollment is required to auto provision the device by using the Device Provisioning Service?

A. the registration ID of the enrollment

B. the primary key of the enrollment

C. the device identity of the IoT hub

D. the hostname of the IoT hub








 

Suggested Answer: A

The registration ID is used to uniquely identify a device registration with the Device Provisioning Service. The device ID must be unique in the provisioning service
ID scope. Each device must have a registration ID.
Note: An individual enrollment is an entry for a single device that may register. Individual enrollments may use either X.509 leaf certificates or SAS tokens (from a physical or virtual TPM) as attestation mechanisms. The registration ID in an individual enrollment is alphanumeric, lowercase, and may contain hyphens.
