What is an array LUN?
A.
a LUN provisioned in ONTAP that is mounted by a connected host
B.
a LUN provisioned on third-party storage that ONTAP will use as a passthrough LUN
C.
a LUN that is used only as a part of a volume group
D.
a LUN provisioned on third-party storage that ONTAP will use in a RAID group
Explanation:
The Data ONTAP software-based scheme provides ownership control only for storage systems running Data
ONTAP; it does not prevent a different type of host from overwriting data in an array LUN owned by a system
running Data ONTAP. Therefore, if multiple hosts are accessing array LUNs through the same storage array
port, be sure to use LUN security on your storage array to prevent the systems from overwriting each other’s
array LUNs.

Yes D is correct.
An array LUN is a logical storage device backed by storage arrays and used by Data ONTAP as a disk. These LUNs are referred to as array LUNs to distinguish them from the LUNs that Data ONTAP serves to clients.
This is from their official study material.
