Why each option
The exhibit displays Fibre Channel output for 4 separate HBAs, each with its own unique node name and port name, totaling 4 WWNNs and 4 WWPNs.
In Fibre Channel, every HBA has one WWNN identifying the node and one or more WWPNs identifying each individual port. The exhibit shows 4 distinct HBA entries, each with a separate WWNN and a single WWPN, resulting in 4 WWNNs and 4 WWPNs total.
One WWNN with four WWPNs would describe a single multi-port HBA, not four separate HBA nodes each with their own node name.
One WWNN and one WWPN describes a single single-port HBA, which does not match an exhibit showing multiple HBA entries.
Four WWNNs and one WWPN is technically inconsistent - each WWPN is bound to a specific node, so four nodes must have at least four WWPNs.
