Which of the following terms describes the situation where a single HBA can represent many World Wide Ports Names on a fabric to give a unique World Wide Port name to a number of hosted virtual machin

VSAN (Virtual Storage Area Network) is a logical partitioning of a Fibre Channel fabric, creating multiple independent SANs over a single physical infrastructure, not a mechanism for virtual WWPNs.

MPIO (Multipath I/O) is a framework that allows multiple paths to storage devices to be used simultaneously for redundancy and load balancing, not for virtualizing WWPNs.

MPLS (Multiprotocol Label Switching) is a data-carrying mechanism for high-performance telecommunications networks that directs data from one network node to the next based on short path labels, unrelated to Fibre Channel HBA virtualization.

NPIV (N-Port ID Virtualization) is a Fibre Channel feature that enables a single physical Fibre Channel host bus adapter (HBA) port to register multiple N-Port IDs (WWPNs) on a Fibre Channel fabric. This allows individual virtual machines running on a host to have their own unique WWPNs, enabling per-VM zoning and LUN masking directly from the storage system.
