What will be disabled as a result of the no service password-recovery command?

A.
password encryption service

B.
ROMMON

C.
changes to the config-register setting

D.
the xmodem privilege EXEC mode command to recover the Cisco IOS image

Explanation:
Password recovery occurs in the ROMMON, if you have forgotten the password and need
to recover. In ROMMON you have the ability to reset the password. Since an attacker that
gains physical access to the router could reboot the device and break the boot sequence to
enter ROMMON and do the same, the “no service password-recovery” command
eliminates the possibility of entering ROMMON.
