An administrator has just changed the IP address of an interface on an IOS device. What else must be done in order to apply those changes to the device?
- Reload the device and type yes when prompted to save the configuration.
- Copy the information in the startup configuration file to the running configuration.
- 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.
- Copy the running configuration to the startup configuration file.
|Explanation & Hint:
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.
