Explanation
Configuration register value 0x2142 sets bit 6, instructing the Cisco router to ignore the startup configuration in NVRAM during boot, which is the standard password recovery method.
Common mistakes.
- A. 0x102 is not a standard Cisco configuration register value and does not map to a defined NVRAM bypass or special boot behavior.
- B. 0x2102 is the factory default configuration register that boots the router normally, loading the startup-config from NVRAM rather than bypassing it.
- C. 0x2120 is not a recognized standard Cisco configuration register setting and does not bypass NVRAM contents.
- D. 0x2124 is not a defined Cisco configuration register value associated with bypassing NVRAM or password recovery.
