In the IoT architectural model, which layer is associated with connecting endpoints?

• A. Application Layer
• B. Middleware Layer
• C. Internet Layer
• D. Physical Layer

Answer: (C)

Connecting endpoints in an IoT architectural model hinges on network connectivity, which is handled by the Internet Layer. This layer provides IP addressing, routing, and inter-network communication so devices can reach each other and exchange data across different networks. The Physical Layer deals with the actual hardware and signals from sensors and actuators. The Middleware Layer sits between the network and applications, handling data translation, processing, and services that enable communication and integration. The Application Layer delivers user-facing services and interfaces. Since connecting endpoints requires scalable addressing and routing across networks, the Internet Layer is the best fit.
