Explanation

VSAN (Virtual Storage Area Network) is a Cisco-proprietary technology specific to Cisco MDS SAN switches, making it the hallmark of a Cisco-designed data center. It allows administrators to create isolated logical SAN fabrics within a single physical infrastructure, much like VLANs do for Ethernet - and it is only native to Cisco equipment.

Why the distractors are wrong:

• A. NPV (N-Port Virtualization) is a vendor-neutral, standards-based feature (FC-BB-5) supported by multiple vendors including Brocade; it is not Cisco-exclusive.
• B. NPIV (N-Port ID Virtualization) is an ANSI/T11 standard allowing multiple virtual ports per physical HBA port - again, multi-vendor and not Cisco-specific.
• D. FCoE (Fibre Channel over Ethernet) is an IEEE/T11 open standard for tunneling FC traffic over Ethernet; Cisco supports it, but so does every other major vendor.

Memory tip: Link VSAN to VLAN - Cisco invented VLANs to virtualize Ethernet, and they invented VSANs to virtualize SANs. Both follow the same "Cisco adds a V" pattern. If the question says "Cisco data center," think VSAN.
