Which command displays a message when the router is accessed?

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

Answer: (A)

When a user connects to a router, banners are used to present an important notice at the start of the session. The message of the day (MOTD) banner is specifically meant to display a message to anyone who accesses the device, regardless of whether they log in or what method they use (console or remote sessions). You configure it with banner motd and surround the message with a delimiter, for example banner motd #Your notice here#. This banner is shown as part of the session startup, so it appears whenever someone accesses the router. This is why it’s the best fit for displaying a message when the router is accessed: it directly targets the access moment and conveys information before or as the session begins. The other options serve different purposes: changing the hostname only alters the device name; setting a line password protects access but does not display a message; and a banner at login would appear before authentication, which is a different point in the access sequence.
