Final answer:
An advantage of storing configuration files to a USB flash drive instead of to a TFTP server is portability, offline access, and added security.
Step-by-step explanation:
An advantage of storing configuration files to a USB flash drive instead of to a TFTP server is that the files can be easily transported and accessed on different devices.USB flash drives are portable and can be used on any computer or device with a USB port. In contrast, a TFTP server requires network connectivity and may not be accessible in all locations or on all devices.
Another advantage is that storing configuration files on a USB flash drive provides offline access. If a network connection is not available or reliable, the configuration files can still be accessed and applied from the USB flash drive. This can be particularly useful in situations where a stable network connection is not guaranteed.
Furthermore, using a USB flash drive for storing configuration files can provide an extra layer of security. The files stored on the flash drive can be encrypted or password protected, adding an additional barrier to unauthorized access to the configuration files.
