The network administrator has forgotten the enable password of the router. Luckily, no one is currently logged into the router, but all passwords on the router are encrypted. What should the administrator do to recover the enable password?

A.
Call the Cisco Technical Assistance Center (TAC) for a special code that will erase the existing password.

B.
Reboot the router, press the break key during bootup, boot the router into ROM monitor mode, and modify the configuration
register so that the current configuration is ignored during normal bootup

C.
Reboot the router, press the BREAK key during bootup, and boot the router into ROM Monitor mode to erase the configuration,
and re-install the entire configuration as it was saved on a TFTP server.

D.
Erase the configuration, boot the router into ROM Monitor mode, press the BREAK key, and overwrite the previous enable
password with a new one.
