Which command would you use to configure console line security on a Cisco IOS device?

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

Answer: (A)

Securing the console line is done by setting a password directly on that line. In line configuration mode, the password command defines what password will be required when someone tries to access the device through the console. For example, configuring the line with password class sets the console password to "class." After this, you’d typically enable login so the device prompts for that password on attempt to console in. This approach provides a straightforward barrier to unauthorized physical access. The other options don’t provide the basic console password mechanism. Using login local would require a local user database and is a different form of authentication. Displaying a banner MOTD or changing the hostname doesn’t impact access control on the console.
