* Router Initialization:
* When a router boots up, it attempts to load its configuration file from the default save directory to initialize.
* If the configuration file is missing, the router defaults to preconfigured parameters to ensure basic functionality.
* Default Parameters:
* These parameters include IP routing, interface defaults, and system-level settings. They allow network administrators to connect and manually configure the router.
* Why Other Options Are Incorrect:
* B: The "initial configuration file" refers to the manually created file, which may not exist.
* C: The "current configuration file" is used during runtime but does not persist through reboots if unsaved.
* D: A "new configuration file" must be manually created and does not exist by default.
