Refer to the exhibit. Which type of port is used to connect an edge switch in NPV mode to the core switch?
The correct answer is D. NP. In NPV (N-Port Virtualization) mode, the edge switch uses NP ports to connect upstream to the core Fibre Channel fabric switch.

Why each option
In NPV (N-Port Virtualization) mode, the edge switch uses NP ports to connect upstream to the core Fibre Channel fabric switch.
E ports are used for ISL (Inter-Switch Links) between two full fabric non-NPV Fibre Channel switches and are not applicable to NPV edge-to-core connections.
TE (Trunking E) ports extend ISL functionality with VSAN trunking between full fabric switches, not for NPV edge switch uplinks to a core.
F ports are fabric ports on the core switch side that accept connections from N-ports or NP-ports; an edge switch in NPV mode presents NP ports, not F ports, on its uplink.
An NP (N-Port Proxy) port is the specific port type used on an NPV-mode edge switch to connect to the upstream core switch's F port. The NP port acts as a proxy, multiplexing all downstream N-port login sessions through a single physical uplink to the core fabric. This port pairing - NP on the edge, F on the core - is the fundamental requirement for NPV operation.
