What does the command o/r 0x2142 provide?

Answer & Solution
Correct Answer: Option B
The default configuration setting is 0x2102, which tells the router to load the IOS from flash and the configuration from NVRAM. 0x2142 tells the router to bypass the configuration in NVRAM so that you can perform password recovery.
