問題

After working all night and successfully configuring a Cisco router for the Ezonexam network you save your changes on the startup config, reboot the router, and go out for a cigarette. When you return, none of your changes are active and the router boots to the initial configuration mode! Which of the choices below indicates the source of your problem?

A.Hardware failure in NVRAM prevents the router from loading the config

B.Startup-config in flash is corrupt and cannot be analyzed

C.Router configuration-register set to bypass startup configuration

D.Startup-config in NVRAM is corrupt and cannot be analyzed

E.None of the above

參考答案
正確答案:C
解析:Explanation:
The default configuration-register setting of 0x2102 loads the IOS from flash and the configuration from NVRAM.
However, for password recovery, you can set the register to 0x2142 and the startup-config file in NVRAM will be bypassed. The problem described here is that the config register was not changed back to 0x2102 before the router was rebooted, so the active configuration is bypassed. Simply setting the config register back to 0x2102 will fix this problem.

Incorrect Answers:
A, B, D. All of these describe hardware or software errors. In the event that this is the problem, errors will be generated and the router will fail to boot properly. In these cases, the router will not return to the initial startup configuration.
