Sliding Windows output a result only when an event enters or leaves the window, capturing data within a specified time span (e.g., 10 minutes) every time a new event is received. Tumbling and Hopping windows run at fixed, scheduled intervals.
This question evaluates your knowledge of Azure Stream Analytics — a core concept tested in Microsoft Certified: Azure IoT Developer Specialty (AZ-220). Understanding Azure Stream Analytics 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.
IoT sensor data arrives in Azure IoT Hub. You need to detect when the average temperature across all sensors exceeds 75°C for any 5-minute window, and send an alert immediately when that threshold is crossed. Which Azure service should you use?
Your Stream Analytics job processes IoT Hub telemetry. You notice that out-of-order events are causing incorrect window calculations because some sensors report data with a delay of up to 10 seconds. How should you configure Stream Analytics to handle this?
A Stream Analytics job processing device telemetry is showing high latency and a large backlog. Which metric should you monitor, and what scaling action is appropriate?
A Stream Analytics query needs to archive telemetry data to Azure Storage and send real-time alerts to a Service Bus Queue. How should you implement this in a single Stream Analytics job?
