Which two descriptions of NPV are true? (Choose two.)

The correct answer is B. lt reduces the number of domain IDs in a fabric. D. It assigns multiple Fibre IDs to a single Port. NPV reduces domain IDs by proxying N-Port traffic through NP-Port uplinks and, combined with NPIV, allows multiple FCIDs on a single physical port.

Why each option

NPV reduces domain IDs by proxying N-Port traffic through NP-Port uplinks and, combined with NPIV, allows multiple FCIDs on a single physical port.

AIt must be configured on all hosts that connect to the NPV switch.

NPV is a switch-level mode configured on the Fibre Channel switch itself, not a per-host configuration applied to connected servers or HBAs.

Blt reduces the number of domain IDs in a fabric.Correct

NPV mode converts a Fibre Channel switch into a proxy edge device that forwards host traffic through NP-Port uplinks to a core switch, so the NPV switch does not register its own domain ID, directly reducing the total number of domain IDs required in the fabric.

CIt combines locally connected N Ports into a single uplink.

NPV forwards N-Port traffic through one or more NP-Port uplinks to the core fabric switch rather than collapsing all connected N-Ports into a single uplink.

DIt assigns multiple Fibre IDs to a single Port.Correct

When NPV operates alongside NPIV (N-Port ID Virtualization), multiple virtual N-Ports each with a unique Fibre Channel ID can be presented over a single physical port, enabling virtualized server environments to register multiple initiators without additional physical HBAs.

EIt is deployed to a VM by using Cisco UCS Manager.

NPV is a Fibre Channel fabric feature configured directly on MDS or Nexus switches, not a virtualization service deployed to VMs through Cisco UCS Manager.
