Internet of Things (IoT) Practice Exam

Which of the following is a common advantage of IoT technology in cities?

1. Improved traffic management

2. Reduced job opportunities

3. Higher energy consumption

4. Increased urban noise levels

The correct answer is: Improved traffic management

Improved traffic management is indeed a common advantage of IoT technology in cities. The implementation of IoT devices enables real-time data collection and analysis, which enhances the efficiency of traffic systems. Smart traffic lights can adjust their timings based on current traffic conditions, minimizing congestion and reducing travel times for commuters. Additionally, connected vehicles and infrastructure can communicate with each other, allowing for better navigation and route optimization. This not only eases traffic flow but also contributes to lower emissions by reducing idling and stop-and-go traffic, leading to a more sustainable urban environment. Other options, such as reduced job opportunities, higher energy consumption, and increased urban noise levels, do not represent advantages of IoT technology in urban settings. In fact, IoT can lead to job creation in tech and maintenance sectors while promoting energy efficiency and potentially lowering noise pollution through better traffic flow and management systems.
