Explanation/Reference:
AD (not C): vSAN 6.0 introduces a new on-disk format that includes VirstoFS technology. This always- sparse filesystem provides the basis for a new snapshot format, also introduced with vSAN 6.0, called vsanSparse.
E: If the underlying is storage is vSAN, if the on-disk format is v2, and if there are no older vmfsSparse/ redo log format snapshots on the virtual machine, vsanSparse format snapshots will be automatically used.
If a virtual machine has existing vmfsSparse/redo log based snapshots, it will continue to get vmfsSparse/ redo log based snapshots until the user consolidates and deletes all of the current snapshots.
Incorrect Answers:
B: A chain of up to 32 snapshots is supported.
F: The new vsanSparse format leverages the underlying sparseness of the new VirstoFS filesystem (v2) on-disk format References:https://storagehub.vmware.com/export_to_pdf/vsansparse-tech-note
