The systems administrator is configuring a new iSCSI storage, which will be presented to several servers. Which of the following should the administrator use to present a LUN to a server?

LUN masking is a storage-array-side access control that hides or reveals specific logical unit numbers (LUNs) on a per-initiator or per-host basis. When the administrator configures masking, only the designated server's iSCSI initiator IQN is permitted to see and mount that LUN. This prevents other servers in the SAN from accidentally accessing or corrupting the volume.

An initiator is the client-side component (the server's iSCSI software or HBA) that originates storage requests; it does not control which LUNs are presented.

A target is the storage array endpoint that hosts LUNs; it is the destination of iSCSI sessions, not the mechanism for selective LUN presentation.

A share is a network file-system construct (SMB/NFS) used in NAS environments; it is not applicable to block-level SAN/iSCSI LUN access control.
