In TCP/IP, which protocol pair is correctly matched with its layer?
UDP is correctly matched with the transport layer, where it offers connectionless, best-effort delivery alongside TCP. HTTP works at the application layer, IP at the internet layer, and Ethernet at the network access layer, so the other pairings are wrong.

- BUDP - Transport layerCorrect
- CIP - Application layer
- DEthernet - Transport layer
Explanation
UDP, like TCP, is a transport layer protocol. HTTP is an application layer protocol, IP belongs to the internet layer, and Ethernet belongs to the network access (link) layer.
