True or False: When restoring an image backup, F-ROM and SRAM files on the controller are erased.

When restoring an image backup on a FANUC robot controller, it is true that F-ROM (Flash Read-Only Memory) and SRAM (Static Random-Access Memory) files are erased. The process of restoring an image backup typically involves reverting the controller to the state captured during the backup, which means all current data in F-ROM and SRAM will be replaced by the data from the backup. This is a fundamental aspect of image restoration, ensuring that the entire system configuration, settings, and any stored programs are fully reverted to the specified point in time.

Choosing this option is based on an understanding of the backup and restoration process within the context of FANUC robot systems, which emphasizes the importance of a complete overwrite of both types of memory during such operations. The other options may suggest varying conditions or exceptions based on specific circumstances or configurations, which do not apply universally across models or backup methods.
