A city deploys smart traffic lights that need to respond to real-time traffic conditions. The cloud has a round-trip latency of 200 ms, which is too slow for emergency vehicle preemption. The city also wants to collect traffic data for long-term planning. Which architecture is best?

Send all data to the cloud and make decisions there

Use a faster cloud region with 50 ms latency

Use local controllers but never send data to the cloud

Run local edge controllers for real-time decisions and send aggregated data to the cloud for planning

In an edge-to-cloud IoT architecture, what is the typical role of the cloud?

To reduce the need for device connectivity

To provide long-term storage, advanced analytics, and global management

To replace edge devices entirely

To perform real-time control of every device

Part of the IoT Hardware and Platforms domain, which makes up ~18% of our current practice bank. EC-Council does not publish an official question count, but from its 120-minute exam (~50–80 total, ~9–14 in this domain), expect 2–4 from this objective — we provide 52 practice questions to prepare you well beyond it.
