You need to deploy a new IoT device.
What should you use as the device identity during attestation?
Correct Answer: C
Explanation
Each device uses its derived device key with your unique registration ID to perform symmetric key attestation with the enrollment during provisioning. To generate the device key, use the key you copied from your DPS enrollment to compute an HMAC-SHA256 of the unique registration ID for the device and convert the result into Base64 format.
