Which of the following is the BEST process to provide data access control to only the hosts authorized to access the LUN?

RAID Masking is not a recognized storage concept for access control; RAID deals with data redundancy and performance.

LUN Masking is a crucial security feature in Storage Area Networks (SANs) that ensures only authorized host servers can "see" and access designated Logical Unit Numbers (LUNs). This process explicitly controls which storage ports present which LUNs to specific host Bus Adapters (HBAs), thereby preventing unauthorized hosts from discovering or accessing sensitive data on unassigned LUNs.

RAID Mirroring is a data redundancy technique (RAID 1) that duplicates data across multiple disks and is unrelated to host access control.

LUN Binding refers to the process of associating a LUN with a host or group of hosts, but LUN Masking is the specific security mechanism that enforces restricted access.
