DP-203 Certification Practice Question #122

Question

You are designing an Azure Stream Analytics job to process incoming events from sensors in retail environments.
You need to process the events to produce a running average of shopper counts during the previous 15 minutes, calculated at five-minute intervals.
Which type of window should you use?

Accepted Answer

The requirement is a running average over the previous 15 minutes, emitted every 5 minutes. In Azure Stream Analytics that is exactly the scheduled-overlap pattern of a hopping window with a 15-minute size and a 5-minute hop. The strong community consensus and Microsoft Learn?s definition align cleanly, so C is well supported.
