Exam 2V0-21.20 topic 1 question 4 discussion

A & E are correct. VMFS can be deployed on three kinds of SCSI-based storage devices: • Direct-attached storage • Fibre Channel storage • iSCSI storage

awsnoob better answer

A & E ESXi 7.0 supports VMFS Versions 5 and 6

VMFS provides the SCSI access layer for virtual machines to efficiently read and write data on the underlying disk. It uses adaptive block sizing for large I/Os, and subblock allocation for small files and directories. VMFS is rigorously tested and certified for a wide range of Fibre Channel and iSCSI storage systems, and it is optimized to support large files while also performing many small concurrent writes. Fibre Channel (FC) – An ANSI-standard, gigabit-speed network technology used to build storage area networks and transmit data. FC components include HBAs, switches, and cabling

Again - only block storage supported

Answer A and E

A & E ESXi can format SCSI-based storage devices as VMFS datastores

A&E yep

Answer is A & E

In order for a filesystem to be made, the underlying storage must be block-based. VSAN and virtual volumes are object-based and NFS is file-based. Hence, A & E.

A and E

Correct
