A water-utility team needs blob-created notifications to reach a Function quickly without a timer scanning the container every five minutes. What approach should they prefer?
Select an answer to reveal the explanation.
Short Explanation
Polling is walking the hallway every five minutes hoping for mail. Event Grid (or the Event Grid–backed blob pattern) rings you when the blob shows up—drop the timer scavenger hunt.
Full Explanation
Event-driven Function triggers avoid latency and waste from timer-based container scans. Event Grid integration with blob-created events is the documented alternative to polling. Speeding up timers, manual portal downloads, or moving to a single VM disk do not provide the scalable event path AZ-204 expects for this trigger comparison.
