Which UDP port is designated for TFTP?

The designated UDP port for Trivial File Transfer Protocol (TFTP) is indeed 69. TFTP is a simple protocol used for transferring files across a network and operates over UDP (User Datagram Protocol) to provide a lightweight method of moving files.

The importance of UDP port 69 stems from TFTP's role in environments that require minimal overhead compared to more complex file transfer protocols such as FTP. TFTP is commonly utilized in situations where file transfers are straightforward, such as in network booting scenarios or when uploading configuration files to network devices.

The other ports mentioned serve different purposes: port 67 is used by the Dynamic Host Configuration Protocol (DHCP) for server requests, port 68 is used by DHCP for client responses, and port 123 is designated for the Network Time Protocol (NTP). This distinction highlights the specific application roles of different ports in network communications.
