Configuring IoT Hub for Stream Analytics
Question
You are operating an IoT solution for a vineyard where a fleet of drones is used to monitor plants for possible infections.
The drones, which have no direct network access, collect local weather data and they download them to docking stations at the end of their trips.
The docking unit then transfers the data in batches to the central IoT Hub.
You need to design a solution to get the data to the IoT Hub.
You want to configure the IoT hub to send the uploaded data directly to a central Stream Analytics job.
Can you configure the IoT Hub for this scenario?

A. B.Correct Answer: B.
Option A is incorrect because when the field devices send telemetry data in batches as files, the file upload endpoint of the IoT Hub has to be used.
To use the upload functionality, an Azure Storage account must be inked to the IoT Hub and it has to be used as an upload target.
Option B is CORRECT because to use the upload functionality, an Azure Storage account must be inked to the IoT Hub and it has to be used as a target.
Stream Analytics cannot be targeted directly.
References:
Yes, you can configure the IoT Hub to send the uploaded data directly to a central Stream Analytics job for this scenario.
To achieve this, you can use the Azure IoT Hub's built-in integration with Azure Stream Analytics. The integration enables IoT Hub to send device telemetry data to an Azure Stream Analytics job for processing and analysis.
Here's how you can configure the IoT Hub to send data directly to Stream Analytics:
Create an Azure Stream Analytics job in the same region as your IoT Hub. You can use the Azure portal to create a Stream Analytics job.
Add an input to your Stream Analytics job that references your IoT Hub. You can use the built-in IoT Hub input in Stream Analytics to add your IoT Hub as a data source.
Create a query that processes the data from your IoT Hub. You can use SQL-like language to write your Stream Analytics query.
Add an output to your Stream Analytics job that sends the processed data to your desired destination. In this case, you can select the output as another Azure service, such as Azure Blob Storage or Azure Event Hubs.
Finally, configure the IoT Hub to send telemetry data to your Stream Analytics job. You can use the Azure portal or the Azure CLI to configure the IoT Hub's built-in integration with Stream Analytics.
By configuring the IoT Hub to send data directly to Stream Analytics, you can streamline your data processing pipeline and gain real-time insights into your vineyard operations.
