Which ONTAP component is used to expose block LUNs to initiators via iSCSI?

• A. Export policy
• B. Volume
• C. iSCSI target
• D. LIF

Answer: (C)

Exposing block LUNs to iSCSI initiators is done by the iSCSI target. In ONTAP, a LUN sits inside a volume, but it becomes accessible to initiators only when there is an iSCSI target presenting that LUN over the network. The target is the endpoint that handles iSCSI protocol communication, maps the LUN to the appropriate initiator group, and serves data through a portal (IP and port). LIFs are just network interfaces used for data paths, export policies control NAS access, and a volume is the data container—not the mechanism that exposes LUNs via iSCSI. So the iSCSI target is the component that exposes block LUNs to initiators.
