How do you set a description on an interface?

• A. description description
• B. set description description
• C. define description description
• D. interface description description

Answer: (A)

To set a description on an interface in Cisco devices, the command is used in interface configuration mode. The correct format is to enter the interface context and then type the command followed by the desired description text. In this case, the command "description description" is correctly formatted to apply a specific text as a description to the selected interface. This command not only helps in documenting the purpose or role of the interface, but it can also aid network administrators in identifying interfaces at a glance when examining the device configuration. While options like "set description" and "define description" may sound plausible, they do not correspond to the Cisco IOS command syntax. The command structure for Cisco devices relies on established keywords, and using "interface" as a command does not apply in the context of setting the description directly. The command needs to be issued in the correct context, which is why the first option aligns with the recognized syntax.
