Which Cisco Internetwork Operating System (IOS) command would be used to set the privileged mode
password to “cisco”?

A.
router(config)# enable password cisco

B.
router# enable secret cisco

C.
router(config)# line password cisco

D.
router(config-router)# enable password cisco

Explanation:
The enable password command is used to set the local password to control access to privileged levels. This
command is executed on the global configuration mode, as in router(config)# enable password cisco. The
syntax of the command is:
router(config)# enable password [level level] {password | [encryption-type] encrypted-password}
The parameters of the command are as follows:
level level: An optional parameter to set the privilege level at which the password applies. The default value
is 15.
password: Specifies the password that is used to enter enable mode.
encryption-type: An optional parameter to specify the algorithm used to encrypt the password.
encrypted-password: Specifies the encrypted password that is copied from another router configuration.
The router# enable secret cisco command is incorrect because the enable secret command must be executed
from global configuration mode, not privileged EXEC mode. In fact, this is the password for which you will be
prompted when you attempt to enter privilege exec mode.
The line password command is incorrect because this command is not a valid Cisco IOS command.
The router(config-router)# enable password cisco command is incorrect because the enable password
command must be entered in global configuration mode.
