IoT Networking and Communication Concepts ISE Practice Questions (Page 7)

Part of the IoT Fundamentals and Networking domain, which makes up ~15% of our current practice bank. EC-Council does not publish an official question count, but from its 120-minute exam (~50–80 total, ~8–12 in this domain), expect 2–3 from this objective — we provide 42 practice questions to prepare you well beyond it.

A smart-agriculture company is deploying soil-moisture sensors across a 10 km² farm. Each sensor wakes every 15 minutes, sends a 50-byte reading, and then sleeps. The sensors are battery-powered and must operate for at least two years. The network team must choose an application-layer protocol and transport. Which combination best meets the requirements?
