Which of the following is a limitation of TFTP?

The limitation of TFTP (Trivial File Transfer Protocol) primarily stems from its lack of security features, including encryption. TFTP is designed to be a simple and lightweight file transfer protocol that operates on UDP (User Datagram Protocol), which does not include mechanisms for securing the data being transferred. As a result, any files sent over TFTP can be intercepted and read by unauthorized users, making it unsuitable for transferring sensitive data where security is a concern.

Additionally, TFTP does not offer user authentication, which further compromises security by allowing anyone with network access to use the protocol for file transfers. This vulnerability is particularly important in environments where data security is essential, as it could lead to potential data breaches or unauthorized access to files.

In other contexts, file transfer protocols that incorporate security features, such as SFTP (Secure File Transfer Protocol) or SCP (Secure Copy Protocol), are preferred when safeguarding data integrity and confidentiality is crucial.
