Exam AZ-220 topic 2 question 8 discussion

Ans is A Registration ID is a required field

I would say the answer is A , Registration ID is mandatory https://docs.microsoft.com/en-us/azure/iot-dps/concepts-device

Ans is A Registration ID for individual device enrollment

I think the question wants to say "which field is mandatory in 'Add enrollment screen'". I that case, only registration id is mandatory. Very confusing question, I totally agree.

It shall be B. Reason - Device Enrollment is already done, now need Primary Key which will be used to create SAS token

Confusing question, question says which details is required, then ans is A. but to auto provision device id is used !

The Device Identity of the IoT Hub Is the correct one. Checked the documents and couple of other sites.

An enrollment is the record of devices or groups of devices that may register through auto-provisioning. The enrollment record contains information about the device or group of devices, including: the attestation mechanism used by the device the optional initial desired configuration desired IoT hub the desired device ID GIven answer is correct Too much confusion in the comments

Answer B is correct. The RegID will be used to generate a symmetric key (e.g. the primary and secondary key) which will be used to authenticate with the DPS during provisioning.

Answer is B. Registration ID is a device identifier not enrollment group, so it is not A. "Open the enrollment and copy the value of your generated Primary Key." https://docs.microsoft.com/en-us/azure/iot-dps/how-to-legacy-device-symm-key

A and/or B for a symmetric device. https://docs.microsoft.com/bs-latn-ba/azure/iot-dps/quick-create-device-symmetric-key-python#prepare-the-device-provisioning-code

Definitely A is the Answer

Ans is A: https://docs.microsoft.com/en-us/azure/iot-dps/about-iot-dps

I will go with A) as "registration ID" is a mandatory field when adding a device individual enrollment in DPS
