What is the main benefit of using TFTP for configuration backups?

Using TFTP (Trivial File Transfer Protocol) for configuration backups is primarily beneficial because it is lightweight and easy to set up. TFTP operates over UDP (User Datagram Protocol), making it less complex than other file transfer protocols that utilize TCP (Transmission Control Protocol). This simplicity leads to a straightforward configuration process, allowing technicians to quickly implement TFTP for uploading and downloading configuration files.

The protocol's lightweight nature also means it consumes fewer resources, which is particularly advantageous in network environments where minimal overhead is desirable. Additionally, since TFTP does not support advanced features like authentication or encryption, its ease of use remains a key advantage when the need for speed and simplicity takes precedence over security.

While the other options present characteristics that might apply to different protocols or methods, they do not align with TFTP's inherent functions. For instance, TFTP is not designed as a secure method of file transfer, nor does it provide encryption. It is also limited in terms of file size, which can constrain larger configurations. Therefore, the primary appeal of TFTP lies in its lightweight setup and operation, making it an excellent choice for straightforward configuration backup tasks.
