Question 1

You are designing an IoT solution that receives telemetry data from 100,000 sensors globally.

The system must ingest up to 2 million events per second. You need a service that can buffer this massive influx of streaming data, partition it for parallel processing, and retain the raw events for up to 7 days so multiple downstream consumer applications can read the data at their own pace.

Which Azure service should you recommend?

Accepted Answer

Look for keywords: 'telemetry', 'millions of events per second', 'buffer', and 'retention'. These point to Event Hubs.

Question 2

What mistakes do candidates make on this AZ-305 question?

Accepted Answer

Confusing Event Hubs with Event Grid or Service Bus. Event Hubs = Telemetry/Big Data. Service Bus = High-value enterprise messages. Event Grid = Reactive discrete events.
