Which two storage protocols can a virtual infrastructure operator use to create a VMFS datastore? (Choose two.)

The correct answer is A. Fibre Channel C. iSCSI. VMFS datastores are deployed on block storage, which can be provided by Fibre Channel or iSCSI protocols.

Why each option

VMFS datastores are deployed on block storage, which can be provided by Fibre Channel or iSCSI protocols.

AFibre ChannelCorrect

Fibre Channel is a block-level storage protocol that provides high-speed data transfer between servers and storage devices, making it suitable for VMFS datastores.

BNFS

NFS is a file-level storage protocol, not block-level, and while it can be used for virtual machine storage, it cannot be used to create a VMFS datastore.

CiSCSICorrect

iSCSI is a block-level storage protocol that encapsulates SCSI commands over standard TCP/IP networks, allowing servers to access storage devices as if they were local, and is commonly used for VMFS datastores.

DCIFS

CIFS (Common Internet File System) is a file-level storage protocol primarily used for shared folders on Windows systems and is not suitable for VMFS datastores.

ESMB

SMB (Server Message Block) is a file-level storage protocol, an evolution of CIFS, and is not used for creating VMFS datastores.
