Which of the following backup media would be MOST appropriate for router configuration files?

Optical media, such as CDs or DVDs, are generally less convenient for frequent, small backups and are becoming obsolete.

Tape drives are typically used for large-scale, long-term archival backups of vast amounts of data, which is excessive for small router configuration files.

Flash drives are highly portable, durable, and offer sufficient storage for small files like router configurations, making them ideal for quick and convenient backups directly from network devices or for field use.

While a hard disk can store the files, it is generally less portable and practical for direct interaction with a router for a quick configuration backup compared to a flash drive.
