What does the show startup-config command reveal?

• A. The current running configuration in RAM
• B. The contents of the saved configuration file
• C. The current status of all interfaces
• D. The routing table of the device

Answer: (B)

The command "show startup-config" displays the contents of the saved configuration file stored in the device's non-volatile memory (NVRAM). This file holds the configuration that will be applied to the device when it is rebooted. It includes information such as interface settings, routing protocols, access control lists, and any other parameters that have been configured and saved by the network administrator. When a device powers on, it reads this startup configuration to initialize its settings before loading the running configuration (which resides in RAM). Understanding the distinction between the startup configuration and the running configuration is crucial; the startup configuration represents the last saved settings, while the running configuration can change during the device's operation. The reference to the current running configuration relates to a different command, typically "show running-config," which shows the active configuration in RAM. The status of all interfaces and the routing table are also reviewed through other specific commands, making the context provided by "show startup-config" particularly focused on the saved configuration that defines what the device is expected to do upon the next boot.
