    A. Nothing must be done. Changes to the configuration on an IOS device take effect as soon as the command is typed correctly and the Enter key has been pressed.
    Explanation
    Refer to curriculum topic: 2.2.3
    Changes to router and switch configurations take effect as soon as the command is entered. For this reason, it is very important that changes to live production devices are always carefully planned before being implemented. If commands are entered that render the device unstable or inaccessible, the device may have to be reloaded, resulting in network downtime.
