Municipal parking sensors must send frequent small telemetry to a city cloud. Which application protocol choice is most fit for efficient telemetry versus chatty HTTP polling?
Select an answer to reveal the explanation.
Short Explanation
Parking sensors whisper tiny updates all day. MQTT-style pub/sub is the walkie-talkie; constant HTTP polling is mailing a novel every second.
Full Explanation
IoT telemetry favors lightweight pub/sub protocols such as MQTT (or CoAP-class patterns) that minimize header and connection overhead for frequent small messages. Continuous HTTP polling, SMTP, or monthly FTP dumps are inefficient or too coarse for near-real-time parking occupancy.
