NEW QUESTION # 49
You have an Azure IoT Central application that includes a Device Provisioning Service instance.
You need to connect IoT devices to the application without first registering the devices.
In which order should you perform the actions? To answer, move all actions from the list of actions to the answer area and arrange them in the correct order.

Answer:

Explanation:

Explanation:
Step: With DPS (Device Provisioning Service) you can generate device credentials and configure the devices offline without registering the devices through IoT Central UI.
Connect devices that use SAS tokens without registering
1. Copy the IoT Central application's group primary key
2. Use the dps-keygen tool to generate the device SAS keys. Use the group primary key from the previous step. The device IDs must be lower-case:
dps-keygen -mk:<group primary key> -di:<device ID>
3. The OEM flashes each device with a device ID, a generated device SAS key, and the application ID scope value.
4. When you switch on a device, it first connects to DPS to retrieve its IoT Central registration information.
The device initially has a device status Unassociated on the Devices page and isn't assigned to a device template. On the Devices page, Migrate the device to the appropriate device template. Device provisioning is now complete, the device status is now Provisioned, and the device can start sending data.
On the Administration > Device connection page, the Auto approve option controls whether you need to manually approve the device before it can start sending data.

Answer: A

Explanation:
You may find it necessary to deprovision devices that were previously auto-provisioned through the Device Provisioning Service.
In general, deprovisioning a device involves two steps:
1. Disenroll the device from your provisioning service, to prevent future auto-provisioning. Depending on whether you want to revoke access temporarily or permanently, you may want to either disable or delete an enrollment entry.
2. Deregister the device from your IoT Hub, to prevent future communications and data transfer. Again, you can temporarily disable or permanently delete the device's entry in the identity registry for the IoT Hub where it was provisioned.
