You have an Azure IoT solution that includes an Azure IoT hub, a Device Provisioning Service instance, and 1,000 connected IoT devices.

All the IoT devices are provisioned automatically by using one enrollment group.

You need to temporarily disable the IoT devices from the connecting to the IoT hub.

Solution: From the Device Provisioning Service, you disable the enrollment group, and you disable device entries in the identity registry of the IoT hub to which the

IoT devices are provisioned.

Does the solution meet the goal?

Show Answer
Correct Answer: A

To temporarily disable the IoT devices from connecting to the IoT hub, you need to perform two primary actions: first, disable the enrollment group in the Device Provisioning Service (DPS) to stop future auto-provisioning of devices, and second, disable the device entries in the identity registry of the IoT hub to prevent existing devices from communicating with the hub. This approach ensures that the devices are temporarily prevented from both auto-provisioning and current communication, effectively meeting the goal.

Key word here is 'temporarily' so disabling is right strategy.
