第3题：

Why might the Ezonexam network administrator set the configuration register to 0x2142 on a 2600 series Cisco router?

A．To boot the IOS from ROM

B．To reset the console password

C．To upload a new version of the configuration file

D．To upload a new version of the IOS

E．To allow a new memory upgrade to be recognized by the router

正确答案：B
解析：Explanation:
About 99 percent of the time someone uses a config-register, it's more than likely because of a lost router password. The two config-registers for recovering passwords are 0x2102 and 0x2142.

The first config-register, 0x2102, 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 0x2102." This is normal.

But let's say you forgot the router's password. To recover this password (as long as it's unencrypted), boot the router and bypass the startup-config using config-register 0x2142; you should then be able to see the password in the startup-config. You can use the same method for encrypted passwords, but you'll need to overwrite the original password with a new one. To change the configuration register, enter the following:
Router(config)# config-register 0x2142

This will instruct the router to bypass the configuration and boot up as if it were a brand new router using factory default settings.
