200-150 · Question #211
Which description of NPIV is true?
The correct answer is C. It assigns multiple Fiber Channel IDs to a single N Port. NPIV (N_Port ID Virtualization) allows a single physical Fibre Channel HBA port to present multiple virtual N_Port identifiers - each with its own WWPN - to the fabric.

Why each option
NPIV (N_Port ID Virtualization) allows a single physical Fibre Channel HBA port to present multiple virtual N_Port identifiers - each with its own WWPN - to the fabric.
Allowing storage traffic to traverse Ethernet networks describes FCoE (Fibre Channel over Ethernet), which is a distinct encapsulation technology unrelated to NPIV.
Exchanging zone information through the fabric describes zone merge or FSPF processes, not the port virtualization function of NPIV.
NPIV works by assigning multiple Fibre Channel IDs (WWPNs) to a single physical N_Port, enabling a single HBA to support multiple virtual machines or virtual HBAs, each with a unique fabric identity. This is the defining technical characteristic of NPIV and is essential for virtualized SAN environments.
NPIV is enabled at the individual switch port level, not on a per-VSAN basis, making this description inaccurate as a defining characteristic.
