Answer: A,C and E.
The NPV feature is an extension to NPIV. The NPV allows the ToR fabric device to behave as am NPIV-based HBA to the core Fibre Channel switch. The ddevice aggregates the locally connected hosts ports (N Ports) into one or more uplinks to the Core SW.
The interface that is connected to the HBA is the F Port. The interface that is connected to the FC SW is the proxy N port (NP Port).
An NPV-enabled SW does not require a domain ID, it’s used at the access layer, acts as a proxy subordinated to the FC SW and most FC services are switched off.
