Which three commands are needed to set up secure access to a router through a console interface? (Choose three)

• A. line console 0
• B. enable
• C. login
• D. password cisco

Answer: (A)

To establish secure access to a router through its console interface, specific commands are necessary to configure the device appropriately. First, entering the command to access the console line, such as "line console 0," is essential. This command allows access to the console line configuration mode, where settings related to console access can be defined. Next, to secure the console access, setting a password is also required. The command "password cisco" accomplishes this by establishing the password necessary for logging into the console session. Finally, the command "login" is crucial as it activates the password requirement for console logins. Without this command, entering a password set on the console line would not be enforced, and users could access the router without any authentication. Thus, to ensure secure access, the combination of entering the console line configuration mode, setting a password, and requiring login authentication effectively secures the console interface on the router.
