What SAN technology can accomplish fabric infrastructure implementation using multiple fabrics?
The correct answer is A. VSAN. VSANs (Virtual SANs) allow a single physical Fibre Channel fabric to be logically partitioned into multiple isolated virtual fabrics, each operating independently.

Why each option
VSANs (Virtual SANs) allow a single physical Fibre Channel fabric to be logically partitioned into multiple isolated virtual fabrics, each operating independently.
VSANs virtualize the physical SAN fabric by creating multiple isolated logical fabrics on the same physical infrastructure, each with its own fabric services, zoning, and domain IDs. This allows multiple independent fabrics to coexist on shared hardware, improving utilization and isolation.
IVR (Inter-VSAN Routing) is used to route traffic between separate VSANs, not to create or implement multiple fabrics.
SCSI is a storage command-set protocol and has no role in fabric virtualization or the creation of multiple virtual fabrics.
NAS (Network Attached Storage) is a file-level storage paradigm using IP networking, entirely separate from SAN fabric technology.
