Which memory holds the OS image used to boot the switch?

Explanation:
The memory that holds the OS image used to boot a switch is flash memory. The OS image is stored in flash so it remains non-volatile across power cycles, and the boot process loads that image into RAM to run. RAM, being volatile, holds the running system and active data, not the stored OS image. NVRAM typically stores the startup configuration, and ROM contains the bootstrap code or a small recovery OS, not the main OS image. So the OS image lives in flash and is loaded into RAM to be executed during boot.
