Which two actions should you perform?

You have an IoT device that gathers data in a CSV file named Sensors.csv. You deploy an Azure IoT hub that is accessible at ContosoHub.azure-devices.net. You need to ensure that Sensors.csv is uploaded to the IoT hub.

Which two actions should you perform? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.
A . Upload Sensors.csv by using the IoT Hub REST AP
C . From the Azure subscription, select the IoT hub, select Message routing, and then configure a route to storage.
D . From the Azure subscription, select the IoT hub, select File upload, and then configure a storage container.
E . Configure the device to use a GET request to ContosoHub.azure-devices.net/devices/ContosoDevice1/ files/notifications.

Answer: AC

Explanation:

C: To use the file upload functionality in IoT Hub, you must first associate an Azure Storage account with your hub. Select File upload to display a list of file upload properties for the IoT hub that is being modified.

For Storage container: Use the Azure portal to select a blob container in an Azure Storage account in your current Azure subscription to associate with your IoT Hub. If necessary, you can create an Azure Storage account on the Storage accounts blade and blob container on the Containers

A: IoT Hub has an endpoint specifically for devices to request a SAS URI for storage to upload a file. To start the file upload process, the device sends a POST request to {iot hub}.azure-devices.net/devices/{deviceId}/files with the following JSON body:

{

"blobName": "{name of the file for which a SAS URI will be generated}"

}

Incorrect Answers:

D: Deprecated: initialize a file upload with a GET. Use the POST method instead.
