A city deploys smart traffic lights that adapt to real-time traffic flow. The system uses sensors and a central control platform. The city wants to reduce congestion but also needs to ensure the system does not fail during a power outage. Which approach is most effective?

Use a manual override for traffic lights

Move the control platform to a different location

Implement a backup power supply for the traffic lights and control system

Reduce the number of sensors to lower power consumption

A city deploys smart streetlights that dim when no motion is detected. The city expects to reduce energy costs and extend bulb life. Which benefit of IoT is most directly achieved by this deployment?

Increased customer satisfaction

Improved operational efficiency

Enhanced data-driven decision making

A utility company deploys smart meters to collect usage data from homes. The data is used for accurate billing and demand forecasting. Which challenge is most likely to arise from this deployment?

Privacy concerns from detailed usage data

A company is designing an IoT system for a smart building. The system includes sensors, a local controller, and a cloud service. The company wants to ensure that the building's critical functions (e.g., fire alarms) continue to operate even if the cloud service is unreachable. Which architectural approach best meets this requirement?

Use multiple cloud providers to ensure redundancy.

All processing in the cloud, with sensors sending data directly to the cloud.

Store all data locally and never use the cloud.

Local processing on the controller for critical functions, with cloud used for non-critical analytics.
