Which option is a benefit of using N-Port Virtualization?

In NPV mode, the switch does not participate in Fibre Channel fabric services or domain ID assignment; it forwards all N-Port logins (FLOGIs) to the upstream NPIV-capable core switch as virtual N-Ports (NPIVs). This means the NPV switch consumes no domain ID of its own, directly reducing the total number of domain IDs used in the fabric and simplifying scalability in large SAN deployments where domain ID space is limited.

Zoning must still be configured on the upstream core or director switches to control access between initiators and targets; NPV mode proxies login requests but does not eliminate the zoning requirement in the fabric.

NPV mode disables local switching, meaning all traffic - even between devices on the same NPV switch - must traverse to the upstream core switch and back, which increases latency rather than reducing it.

Trunking on an NPV switch requires the upstream switch to support NPIV trunking and is configured as a separate feature; NPV mode alone does not enable or guarantee trunking capability.

The upstream switches must be explicitly configured to support NPIV so they can accept proxy FLOGI requests from the NPV switch; upstream configuration is a prerequisite, not an optional step.
