Which two storage technologies are supported for MSCS? (Choose two.)

VAAI (vStorage APIs for Array Integration) is a set of storage offload APIs, not a storage protocol, and cannot be used as a datastore backing for MSCS cluster disks.

NFS is a file-based protocol that does not expose raw block devices and does not support the SCSI persistent reservations that MSCS relies on for cluster arbitration.

iSCSI is a block storage protocol that delivers SCSI commands over IP networks and supports the persistent SCSI reservations Windows clustering requires for shared-disk access.

Fibre Channel (FC) is a block storage protocol that natively supports SCSI reservations and has been a supported MSCS backing store in VMware environments since early vSphere releases.
