In IOS command structure, what is the difference between a keyword and an argument?

• A. A keyword is a specific parameter. An argument is not a predefined variable.
• B. An argument is a specific parameter. A keyword is not predefined.
• C. Both have predefined values.
• D. Keywords and arguments are the same.

Answer: (A)

In IOS command structure, the action and its parameter are built from a fixed part and a variable part. The fixed part, the keyword, identifies what you want to do or which parameter you’re configuring. The variable part, the argument, supplies the actual value the command will use—this value can change with each use and isn’t predefined by the command itself. For example, in configuring an interface, the keyword interface names the parameter to configure, while the argument GigabitEthernet0/1 specifies exactly which interface you’re targeting. The keyword stays the same, but the argument can be anything valid for that command. So the keyword is a specific, predefined piece of the syntax that tells IOS what to do, while the argument is the actual data you provide to that command, not a fixed predefined value.
