What is the UDP port number assigned for TFTP?

The correct answer is 69, which is the UDP port number assigned for Trivial File Transfer Protocol (TFTP). TFTP is a simplified version of the File Transfer Protocol (FTP) that is used for transferring files over the Internet or an intranet. It operates over UDP rather than TCP, making it connectionless and lightweight, suitable for scenarios where complexity and overhead need to be minimized, such as in embedded systems or when booting devices across the network.

Other options mention ports that are reserved for different protocols: port 68 is generally used by the Dynamic Host Configuration Protocol (DHCP) for client requests, port 161 is used for the Simple Network Management Protocol (SNMP), and port 514 is utilized by the Syslog protocol for system logging. Understanding the specific functions and corresponding port assignments of different protocols is crucial for effective network management and security.
