The command used to save the running configuration to the startup configuration in Cisco devices is indeed "copy running-config startup-config." This command ensures that any changes made to the device's configuration while it was operational (the running configuration) are written to the startup configuration file. This file is used to load the configuration when the device is rebooted, ensuring that your settings persist across power cycles or reboots.

Using this command is essential in network management to ensure that configuration changes are not lost when the device restarts. This practice helps maintain network stability and ensures that the network operates as intended.

The other choices do not accurately reflect Cisco IOS command syntax or functionality. "Save config," "store running-config," and "backup config" are not valid commands in Cisco IOS for saving configurations. It is important to use the correct syntax provided by Cisco to effectively manage networking devices.
