Understanding the Importance of the ‘copy running-configuration startup-configuration’ Command in Router Configuration Management

After several configuration changes are made to a router, the copy running-configuration startup-configuration command is issued. Where will the changes be stored? A) flash ROM. B) NV RAM. C) RAM.  D)TFTP server

The “copy running-configuration startup-configuration” command is used to save the changes made to the running configuration of a router, so that they persist after a reboot.

The changes will be stored in the startup configuration file, which is located in non-volatile random-access memory (NVRAM). NVRAM is a type of memory in a router that retains its content even when the router is turned off or restarted.

The startup configuration file is loaded into the router’s memory (RAM) during the boot process and becomes the active running configuration. The running configuration is volatile, meaning it is lost when the router is powered off or restarted, unless it is saved to the startup configuration.

Flash memory (also known as flashROM) on a router is used to store the operating system (IOS), configuration files, and other data. However, the startup configuration is not stored in the flash memory.

The configuration register is a setting in the router that determines how the router boots up and where it looks for configuration files. It does not directly store the changes made to the configuration.

A TFTP (Trivial File Transfer Protocol) server is a network service that allows files to be transferred between devices. It can be used to back up or restore configuration files, but it is not directly involved in the “copy running-configuration startup-configuration” command.
