A solution is setup with a Volume Guarantee = volume, LUN reservation = off, Fractional
Reserve = 0%, Snap Reserve = 0%, auto_delete = volume, auto_grow = on, try_first =
autosize. Which of these choices best describes the use of these settings for our Space
Policy?

A.
when you want to set aside overwrite reserve space for the LUNs so that writes never fail
with the presence of Snapshots

B.
when you want to use thinly provisioned LUNs to overcommit the volume and increase
storage efficiency

C.
when you want Data ONTAP to start deleting Snapshots to recover space from the
volume before growing the volume

D.
when you want to guarantee space for Snapshots by letting the volume autogrow
