UDP Port 69

Trivial file transfer protocol (TFTP) operates over UDP port 69.

Explanation:

UDP port 69 uses the Datagram Protocol, a communications protocol for the Internet network layer, transport layer, and session layer. This protocol when used over PORT 69 makes possible the transmission of a datagram message from one computer to an application running in another computer. UDP is used with IP (the Internet Protocol) and UDP Port 69 is connectionless which means it does not give reliable communication; it's up to the application that received the message on Port 69 to process any errors and verify correct delivery.
