When a router is powered on, where will the router first search for a valid IOS image to load by default?

• RAM
• ROM
• flash memory
• NVRAM

Explanation: By default, if no boot system commands are in the configuration, a router will load the first valid Cisco IOS image in flash memory and run it. RAM is active memory that is not used to store image files. NVRAM stores configuration files. ROM stores a minimal version of the Cisco IOS image that can be used to provide limited functions if a valid IOS image is not available in flash memory.
