David is a network administrator. He has forgotten the password to one of your routers. After a password recovery procedure, the router returns to its normal operation. What is the value that the config-register set to after the password recovery?
  1. 0x2102
  2. 0x2112
  3. 0x2104
  4. 0x2142
Explanation
Answer - A - The value of the config-register will be set to 0x2102 after the password recovery procedure.

Key Takeaway: Routers use 16-bit software configuration register, which is used to set specific system parameters. The settings for the software configuration register are written into nonvolatile random access memory (NVRAM). The lowest four bits of the configuration register (bits 3, 2, 1, and 0) form the boot field. The order in which the switch/router looks for system bootstrap information depends on the boot field setting in the configuration register.
