An administrator is setting up software RAID 5 on a Windows Server with two volumes for two separate hard drives, but the option for RAID 5 is grayed out. Which of the following is the MOST likely…
The correct answer is C. Raid 5 requires three volumes. Software RAID 5 requires a minimum of three physical disks to function, and with only two volumes configured, the option to create a RAID 5 array will be unavailable.
Question
An administrator is setting up software RAID 5 on a Windows Server with two volumes for two separate hard drives, but the option for RAID 5 is grayed out. Which of the following is the MOST likely reason why?
Options
- AThe disks have been setup as dynamic.
- BWindows does not support software RAID 5.
- CRaid 5 requires three volumes.
- DThe page file must be at least 4GB to support RAID 5.

Why each option
Software RAID 5 requires a minimum of three physical disks to function, and with only two volumes configured, the option to create a RAID 5 array will be unavailable.
Dynamic disks are a prerequisite for creating software RAID volumes on Windows Server, so this would enable, not disable, the RAID 5 option if other requirements were met.
Windows Server operating systems do support software RAID 5 functionality.
Software RAID 5, like its hardware counterpart, fundamentally requires at least three physical disks to distribute data and parity information. This minimum number of disks is essential for RAID 5's data redundancy and performance features. When only two volumes are available, the system cannot meet this requirement, thus graying out the RAID 5 creation option.
The size of the page file has no direct impact on the ability to configure a RAID 5 array.
