What are two purposes of a USB thumb drive? (Choose two.)

USB thumb drives on Cisco devices function as external, non-volatile storage media. Their two primary purposes in a field service context are for file management tasks critical to device maintenance and deployment. This includes copying configuration files to the device for initial setup or from the device for backup. It also involves transferring Cisco IOS software images, which is essential for performing system upgrades, downgrades, or recovery from a corrupted image. These functions allow technicians to manage devices efficiently without constant network connectivity.

A. While a system log can be manually copied as a text file to a USB drive, this is not a primary purpose; logs are typically streamed to a syslog server.
C. Hardware information is obtained using show commands. The output can be saved to a file and copied, but this is an indirect use, not a primary function.
E. A USB drive provides storage, which is distinct from system memory (RAM). It cannot be used to increase the amount of memory available for running processes. ---
