Which of the following allows multiple hosts that are connected to the same storage array to only access their assigned storage?

VLANs operate at the network layer to segment network traffic, not to control access to specific LUNs on a storage array.

LUN masking is a security and access control mechanism used in storage area networks (SANs) to restrict which servers (hosts) can access specific Logical Unit Numbers (LUNs) on a shared storage array. This ensures that each host only sees and can access the storage assigned to it, preventing unauthorized access and data corruption.

Zones are used in Fibre Channel fabrics to control which devices can communicate with each other, but they do not specifically restrict access to LUNs on a storage array.

VSANs (Virtual SANs) are used in Fibre Channel fabrics to create logical isolation of fabric devices, similar to VLANs for Ethernet, but they do not directly control LUN access for individual hosts.
