Which three statements are true regarding vsanSparse snapshots? (Choose three.)
A. They require vSAN 6.0 or higher.
B. They support up to 24 snapshots
C. They use a copy-on-write format
D. They use an always-sparse format.
E. They are supported if a virtual machine has machine has existing vmfsSparse snapshots
F. They are supported if the on-disk format is v1 or higher
Correct Answer: ADE
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
