What command displays a message when the router is accessed?

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

Answer: (B)

The command that displays a message when the router is accessed is the one that configures a message of the day (MOTD) banner. This type of banner serves as a notice to anyone accessing the router, informing them of important information or a warning before they proceed to use the command line. By using the proper syntax, as shown in the correct answer, you can set a custom message that will be displayed at the beginning of a terminal session. The "#" symbol denotes the start and the end of the message content, allowing administrators to define a message that can include a warning or useful procedural information about the router. In contrast, the other commands serve different purposes. Setting a password under the vty lines establishes a method of securing access to the router but does not output any message. Configuring the hostname merely changes the device's name without providing a user-facing message. The enable secret command is used specifically to set a more secure password for privileged EXEC mode but does not display information when accessing the router. Thus, using the MOTD banner sets clear communication for users accessing the device, making it the most appropriate command for displaying a message during access.
