Which of the following is an example of a Network Layer protocol?

The correct choice is indeed an example of a Network Layer protocol because it is responsible for routing packets of data between devices across different networks. Specifically, it facilitates the addressing and forwarding of data packets, enabling communication between devices that are not on the same local network.

This protocol operates at the Network Layer of the OSI model, which is the third layer. Its key functions include logical addressing, which allows for the identification of devices across complex networks, and packet forwarding, which is essential for establishing paths for data to travel over an internetwork.

In contrast, the other options belong to different layers or categories of protocols. For instance, TCP and UDP are Transport Layer protocols that are responsible for facilitating end-to-end communication between devices, while HTTP is an application layer protocol used specifically for transmitting hypertext over the web. This distinction helps to clarify the roles that different protocols play within the overall networking framework.
