Which two files, if found, are copied into RAM as a router with the default configuration register setting boots up?

When a router with the default configuration register setting boots up, two files are copied into RAM:

1. IOS (Internetwork Operating System) file: This is the operating system file of the router. It is loaded into RAM so that the router can use it to perform its functions. The IOS file is typically stored in the router's flash memory.

2. Startup Configuration file: This file contains the router's configuration settings. It is loaded into RAM so that the router can use these settings while it is operating. The Startup Configuration file is typically stored in the router's NVRAM (Non-Volatile Random Access Memory).

So, in summary, the two files that are copied into RAM as a router with the default configuration register setting boots up are the IOS file and the Startup Configuration file.
