2V0-622D Question #263: Real Exam Question with Answer & Explanation

The correct answer is A: VMFS6 (default) and VMFS5. ESXi 6.5 supports both VMFS6 and VMFS5 on 512e (512-byte emulation) sector format drives, with VMFS6 being the default file system for new datastores.

Question

An administrator procured a new server on which to install ESXi 6.5. The server is equipped with local Serial Attached SCSI (SAS) disks with 512e format (512bytes sector emulation). Which file system does VMware support on this type of disk?

Options

AVMFS6 (default) and VMFS5
BVMFS5
C512e format is not supported
DVMFS6

Explanation

ESXi 6.5 supports both VMFS6 and VMFS5 on 512e (512-byte emulation) sector format drives, with VMFS6 being the default file system for new datastores.

Common mistakes.

B. VMFS5 alone is not the complete answer because ESXi 6.5 introduced VMFS6 with full 512e support, and VMFS6 is actually the default - omitting it makes this answer incomplete.
C. 512e format is explicitly supported in ESXi 6.5 and later by both VMFS5 and VMFS6; only 4Kn (native 4096-byte sector) drives have support limitations in VMFS.
D. While VMFS6 is the default and supports 512e, this answer is incomplete because VMFS5 also supports 512e format and is a valid supported option on ESXi 6.5.

Concept tested. VMFS version compatibility with 512e sector format disks
