What additional information will Easy Restore back up starting with iDRAC revision 2.20.20.20?

The correct answer, OEM ID, signifies that starting with iDRAC revision 2.20.20.20, Easy Restore has been enhanced to include the functionality of backing up the OEM ID. The OEM ID is a unique identifier associated with Original Equipment Manufacturers (OEMs) that allows systems to be better integrated and managed according to the manufacturer's specifications and customizations. This additional information provides crucial context for system recovery and restore operations, ensuring that OEM-specific configurations and values are retained, which can be vital for compatibility and operational consistency.

The other options, such as BIOS settings, network settings, and RAID configurations, were typically part of Easy Restore's capabilities prior to this version and do not represent the new enhancements introduced in this particular iDRAC update. Understanding the significance of including the OEM ID helps to appreciate how system identification and configuration fidelity are maintained during recovery operations.
