Explanation
In a SAN environment, confidentiality is achieved through access control mechanisms that prevent unauthorized hosts from accessing storage. Zoning (B) is a switch-level SAN fabric configuration that creates logical groups, restricting which initiators (servers) can communicate with which targets (storage), preventing unauthorized hosts from even 'seeing' the storage. LUN masking (E) is a storage array-level control that restricts which specific server HBAs can access particular LUNs, adding a second layer of access control beyond zoning. Together they implement defense-in-depth for SAN confidentiality. Deduplication (A) improves storage efficiency. Snapshots (C) support recovery and availability. Multipathing (D) provides path redundancy and load balancing. None of A, C, or D address confidentiality.
