You have created an individual enrollment in the Device Provisioning Service and you write the following code to register the device: 
<pre class="brush:python;">provisioning_device_client = ProvisioningDeviceClient.create_from_symmetric_key(
Provisioning_host = “my-dps-001.azure-devices-provisioning.net”,
Device_id = “device-004”,
Id_scope = “0ne00000A0A”,
Symmetric_key = “zRuEuGKag+kQKV+T1QGakR...stfha6dhIPWvdD1nRxK5T0KGKA+nQ”,
)
</pre>
Which of the parameters is wrong and should be replaced with another one to make the code valid?

Answer options:

A.provisioning_host
B.id_scope
C.symmetric_key
D.device_id

Correct Answer: D
Option A is incorrect because the host running the Device Provisioning Service is required.
Option B is incorrect because the ID scope uniquely identifies the provisioning service the device will register. It is required.
Option C is incorrect because it is the symmetric key that will be used to create the shared access signature token to authenticate the device with the DPS. It is required.
Option D is CORRECT because the device_id is not a parameter for the device provisioning method. It is the registration_id which has to be used to uniquely identify the device in the DPS.
