  3. ROM; Read only memory - Stores a bootstrap program that is loaded when the switch first power on
    Bootstrap program finds the full Cisco IOS image and manages the process of loading Cisco IOS into RAM, at which point Cisco IOS takes over ops of the switch
  4. NVRAM; Nonvolatile RAM stores the initial or startup configuration file that is used when the switch is first powered on and when the switch is reloaded
20
Q

Configuration File Purpose ( 2 Types )
