You have an Azure IoT hub that has a hostname of contoso-hub.azure-devices.net and an MCU-based IoT device named Device1. Device1 does NOT support Azure IoT SDKs.
You plan to connect Device1 to the IoT hub by using the Message Queuing Telemetry Transport (MQTT) protocol and to authenticate by using X.509 certificates.
You need to ensure that Device1 can authenticate to the IoT hub.
What should you do?

• A.Create an Azure key vault and enable the encryption of data at rest for the IoT hub by using a customermanaged key.
• B.Enable a hardware security module (HSM) on Device1.
• C.From the Azure portal, create an IoT Hub Device Provisioning Service (DPS) instance and add a certificate enrollment for Device1.
• D.Add the DigiCert Baltimore Root Certificate to Device1.
