Explanation:
About 99 percent of the time someone uses a config-register, it’s more than likely because of a lost router
password. Normally, the two config-registers for recovering passwords are 0×2102 and 0×2142.
The first config-register, 0×2102, is the normal config-register if you boot the router from internal Flash. You
can see this config-register by using the show version command.
In this output, you’ll notice the last line says, “Configuration register is 0×2102.” This is normal.

Booting up the Router:
Cisco routers can boot Cisco IOS software from these locations:

QUESTION 381
What will a new Certifyme router do during startup if a configuration file is not located in NVRAM?
A. It will search for the configuration file in the locations specified by boot system commands.
B. It will search for the configuration file in flash and if no configuration file is found there, it will enter the setup
dialog.
C. It will search for the configuration file on a TFTP server and if no configuration file is found there, it will enter
the setup dialog.
D. It will search for the configuration file in flash and if no configuration file is found there, it will load a limited
configuration file from ROM.
E. It will search for the configuration file on a TFTP server and if no configuration file is found there, it will load
a limited configuration file from ROM.
Answer: C

CISCO DEVICES
Explanation/Reference:
Explanation:
When a router boots and is able to locate the IOS it begins to load the configuration file.
The configuration file, saved in NVRAM, is loaded into main memory and executed one line at a time. These
configuration commands start routing processes, supply addresses for interfaces, and set media
characteristics.
If no configuration file exists in NVRAM, the router attempts a network boot and sends a broadcast request for
the file on a TFTP server. If this is also not found, the operating system executes a question-driven initial
configuration routine called the system configuration dialog.
