CCNA Certification And CCENT Certification:

What configuration register setting causes the router to ignore the contents of NVRAM upon the next reload? As a result, what mode will the router boot into?

Answer: The following command sets the router's config register to ignore NVRAM contents the next time the router is reloaded:

Router1(config)#config-register 0x2142

This is verified by show version:

Router1#show version
Configuration register is 0x2102 (will be 0x2142 at next reload)

When you reload the router, it'll go into Setup Mode.
