Running memory that the switch uses for operations. Changes to the current configuration are stored in the "running-configuration".

• A. RAM
• B. ROM
• C. Flash Memory
• D. NVRAM

Answer: (A)

The running configuration is kept in RAM because RAM is the active, fast, volatile workspace the switch uses while it’s operating. Edits to the configuration update this RAM copy, which is why it’s called the running configuration. If you don’t save the changes, a reboot will clear RAM and the device will load the previous configuration from non-volatile memory. That non-volatile memory stores the startup configuration (and this is typically in NVRAM). In contrast, ROM holds the bootstrap and sometimes a minimal bootloader, and Flash stores the IOS image and other files, not the live running configuration. So the memory that holds the running-configuration is RAM.
