Internet of Things (IoT) Practice Exam

What is a common application of ZigBee technology?

1. High-speed internet access

2. Home automation

3. Data center networking

4. Cloud-based services

The correct answer is: Home automation

ZigBee technology is widely recognized for its application in home automation due to its low power consumption, ability to create mesh networks, and support for a large number of devices. This makes it particularly suitable for controlling and monitoring smart home devices like lights, thermostats, and security systems. In a home automation setup, ZigBee allows devices to communicate efficiently with one another over short distances while maintaining low energy requirements, which is essential for battery-powered devices. The mesh networking capability extends the range of coverage, enabling devices placed further away from the hub to relay information through other ZigBee devices. Thus, the robustness and efficiency of ZigBee make it an ideal choice for managing various interconnected home devices, which aligns perfectly with the needs of home automation systems. Other options like high-speed internet access, data center networking, and cloud-based services do not utilize ZigBee technology due to their different requirements for speed, bandwidth, and connectivity which ZigBee is not designed to meet.
