Final answer:
Windows Server 2019 does not support RAID 10 natively, but it does support RAID levels 0, 1, and 5. RAID 10 can only be implemented using nested RAID levels and is better suited to hardware RAID configurations.
Step-by-step explanation:
The RAID level configuration that is not supported by Windows Server 2019 is RAID 10. While Windows Server 2019 does support RAID levels 0, 1, and 5, it does not support RAID 10 natively. Instead, RAID 10 functionality needs to be implemented using nested RAID levels, specifically by creating a RAID 0 array over two RAID 1 arrays. This type of configuration is also known as RAID 1+0 and is typically implemented through hardware RAID configurations rather than through the operating system.
RAID 0 (striping) spreads data across multiple disks for improved performance but offers no redundancy. RAID 1 (mirroring) duplicates data on two disks, providing fault tolerance. RAID 5 (striped with parity) also spreads data and parity information across multiple disks, allowing for the recovery of data in case one drive fails.
