Which command provides security on the console?

• A. Router(config-line)# password class
• B. Router(config-line)# enable secret
• C. Router(config)# banner motd #
• D. Router(config)# hostname CL1

Answer: (A)

Requiring a password on the console line is how you control direct device access. On Cisco devices, you secure console access by configuring a password on the console line and enabling login so that anyone connecting to the console must enter that password. The command shown sets a password for the line, which is the step that actually enforces authentication at the console. In practice you’d apply it on the console line (line console 0), along with login, so the password prompt appears when someone connects via the console. Other options don’t protect console access: enable secret guards privileged EXEC after you’ve logged in, not the initial console sign-on; a banner MOTD is just a message; and the hostname simply names the device.
