Which file transfer protocol transfers a file using UDP instead of TCP and is typically used on local networks?

• A. tftp
• B. http
• C. smtp
• D. imap

Answer: (A)

Trivial File Transfer Protocol uses UDP instead of TCP, making it lightweight and fast for simple file transfers on a local network. UDP is connectionless and does not guarantee delivery, ordering, or error checking like TCP does, which is fine for small, uncomplicated transfers in trusted LAN environments. TFTP is designed for these quick, uncomplicated tasks and is commonly used for network bootstrapping and device configuration on local networks. In contrast, HTTP, SMTP, and IMAP all run over TCP, which provides reliable, ordered delivery and is better suited for web pages and email traffic, where data integrity and reliability are important.
