Which characteristic describes TFTP?

TFTP (Trivial File Transfer Protocol) is a simple, connectionless protocol that uses UDP port 69. A key characteristic is that it allows anonymous file transfer, meaning it does not require authentication (usernames or passwords). This makes it suitable for specific tasks like booting diskless workstations or transferring configuration files to network devices where security is less of a concern or handled by other means. The other options are incorrect: TFTP does not use separate control and data connections; it uses a single UDP port for both. FTP uses separate control and data connections. TFTP relies on UDP port 69, not TCP port 20. TCP port 20 is used by FTP for data. TFTP does not provide encryption; it transfers data in plain text. Secure protocols like SFTP or FTPS provide encryption.
