Correct Answer
Configure IoT Hub File Upload to associate a storage account — devices upload directly to Azure Blob Storage using SAS URIs provided by IoT Hub
Why This Answer Is Correct
IoT Hub File Upload allows devices to upload large files directly to Azure Blob Storage. IoT Hub provides a temporary SAS URI to the device, the device uploads directly to Blob Storage, and then notifies IoT Hub when complete. IoT Hub then sends a file upload notification to the backend service. This handles files up to 256 GB.
This question evaluates your knowledge of Azure IoT Hub — a core concept tested in Microsoft Certified: Azure IoT Developer Specialty (AZ-220). Understanding Azure IoT Hub is essential for designing scalable, secure, and cost-effective cloud architectures. Mastery of this topic will help you answer scenario-based questions confidently on exam day.
You are building an IoT solution where 50,000 devices must send telemetry every 30 seconds. Your IoT Hub is receiving messages but you are hitting throttling errors. Which action should you take first?
A field device needs to receive configuration updates from the cloud and report its current state back. The configuration properties are set by the backend and the device reports its actual state. Which IoT Hub feature is designed for this pattern?
You need to invoke a firmware update on a specific device immediately and wait for a response to confirm it started. The operation must complete within 30 seconds or be considered failed. Which IoT Hub feature should you use?
Your IoT solution requires sending a firmware binary to 10,000 devices simultaneously over the next 24 hours. Each device must receive the same file. Which IoT Hub capability is designed for this at-scale operation?
Your IoT Hub receives messages from both temperature sensors and pressure sensors. Temperature messages have a custom property 'sensorType=temperature'. You need to route temperature messages to Azure Blob Storage and pressure messages to a Service Bus Queue, without duplicating messages. How do you configure this?
