A storage administrator wants to enable NPV in a Fibre Channel edge switch. Which configuration is supported in this mode?

Question

Options

• ACisco Fabric Services distribution over Fibre Channel
• BE Port connectivity to the core switch
• Clocal switching of east-west traffic
• DDynamic Port VSAN Membership

• A
  82% (18)
• B
  5% (1)
• C
  9% (2)
• D
  5% (1)

Explanation

Cisco Fabric Services (CFS) distribution over Fibre Channel remains operational in NPV mode because NPV switches still forward FC frames, allowing CFS to propagate configuration data across the fabric - it doesn't require the edge switch to run full fabric services.

B is wrong because NPV mode replaces E ports with NP (N-Port Proxy) ports for uplinks to the core switch - E ports require full fabric participation, which NPV deliberately disables to reduce domain ID consumption.

C is wrong because local switching (east-west traffic between devices on the same NPV switch) is explicitly disabled in NPV mode - all traffic must traverse the uplink to the core NPIV-enabled switch, which is a fundamental trade-off of the NPV design.

D is wrong because Dynamic Port VSAN Membership (DPVM) is not supported in NPV mode - VSAN assignment is managed by the core switch, not the edge NPV switch.

Memory tip: Think "NPV = No Ports are E-ports, No local switching, No DPVM - but CFS still flows through it." NPV strips the switch down to a proxy forwarder, so anything requiring local fabric intelligence is gone, but passive protocol forwarding like CFS survives.
