Which UDP port is primarily used for TFTP communication?

Port 67
Port 68
Port 69
Port 70

The correct answer is: Port 69

TFTP, or Trivial File Transfer Protocol, primarily uses UDP port 69 for its communication. This choice is correct as TFTP is a simple protocol designed to transfer files over a network without the overhead of more complex protocols such as FTP. It operates over UDP, which is a connectionless protocol, making TFTP suitable for environments where packet loss is acceptable and speed is prioritized over reliability. The alternative ports listed in the other options serve different purposes. Port 67 is typically associated with the Dynamic Host Configuration Protocol (DHCP) server, which is used for dynamically assigning IP address configurations. Port 68 is generally used by DHCP clients to receive these configurations. Port 70 is assigned to Gopher, an early internet protocol for distributing, searching, and retrieving documents. Each of these ports serves distinct roles in network communication, thereby reinforcing the specificity of port 69 for TFTP.
