200-150 Question #211: Real Exam Question with Answer & Explanation

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.

Question

Which description of NPIV is true?

Options

AIt allows storage traffic to transverse Ethernet networks.
BIt exchanges zone information through the fabric.
CIt assigns multiple Fiber Channel IDs to a single N Port.
DIt is enabled on a per-VSAN basis.

Explanation

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.

Common mistakes.

A. Allowing storage traffic to traverse Ethernet networks describes FCoE (Fibre Channel over Ethernet), which is a distinct encapsulation technology unrelated to NPIV.
B. Exchanging zone information through the fabric describes zone merge or FSPF processes, not the port virtualization function of NPIV.
D. NPIV is enabled at the individual switch port level, not on a per-VSAN basis, making this description inaccurate as a defining characteristic.
