Which are among the valid steps in the process of recovering a password on a Cisco router? (Choose all that apply.)

  • Restart the router.
  • Configure the enable secret password.
  • Enter the router diagnostic mode.
  • Enter user mode.
  • Answer the security question to recover the password.
Three of the steps that should be performed while recovering a password on a Cisco router are to restart the router in ROMMOM mode, enter ROMMON mode (router diagnostic mode) and reset the enable secret password. The complete password recovery process on a Cisco Router is as follows:

Configure the router so that it starts without reading the non-volatile random access memory (NVRAM). This is also referred to as the system test mode, which you enter by changing the configuration register. You must first restart the router and within 60 seconds press Break on the terminal keyboard. Then the router will skip normal reading of the startup configuration file and will go to the ROMMON prompt (shown below this text section). At this command prompt, type confreg 0x2142 to instruct the router to boot to flash memory at the next reboot. When it does, it will ignore the startup configuration file again and will behave as if it had no configuration, as a new router would.

rommon 1> confreg 0x2142

Type reset to reboot the router.
Enter enable mode through the test system mode.
View the existing password (if it can be viewed, it may be encrypted), configure a new password, or delete the configuration.
Configure the router to start by reading the NVRAM, which is done by resetting the configuration register to its normal value. Run these commands:

Router#configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#config-register 0x2102

Restart the router.

You will proceed through user mode but to make any changes you make must be at the global configuration prompt.

Finally, there is no way to recover a password by answering a security question.
