ZIGBEE Practice Exam

Zigbee is a low-power, wireless communication protocol designed for short-range, low-data-rate applications in IoT (Internet of Things) and home automation. It operates on the IEEE 802.15.4 standard and provides a reliable and efficient way to connect and control devices in smart homes, industrial automation, healthcare, and other IoT applications. Zigbee networks typically consist of a coordinator, routers, and end devices, forming a mesh network topology for decentralized communication. Skills covered in Zigbee certification include understanding Zigbee protocol stack, network configuration, device interoperability, security mechanisms, and troubleshooting techniques. Prerequisites usually include basic knowledge of wireless communication principles, familiarity with IoT concepts, and understanding of networking protocols.
