Which command initiates the transfer of a Cisco IOS image over IP from ROMMON?
The tftpdnld command is specifically designed to initiate a TFTP (Trivial File Transfer Protocol) transfer of an image within ROMmon mode on a Cisco device. Here's why it's the correct answer:
ROMmon Functionality: ROMmon (Read-Only Memory Monitor) is a basic operating system mode used when the main Cisco IOS is unavailable. The tftpdnld command works from ROMmon to download a new IOS image.
TFTP Protocol: The tftpdnld command utilizes TFTP, which is a simple and reliable protocol commonly used for transferring Cisco IOS images.
Purpose: The command is used primarily for recovering corrupt images or upgrading to a different IOS version.
Why other options are incorrect:
Xmodem: XMODEM is an older and less reliable file transfer protocol that's less suitable than TFTP for Cisco IOS image transfers.
copy tftp: flash: This command format is used within the Cisco IOS itself, not in ROMmon mode.
copy flash: tftp: This command format would attempt to upload an image from flash memory to a TFTP server, instead of downloading an image.
