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

Suggested Answer: A 🗳️
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.
