An engineer must choose the World Wide Port Name for the Cisco UCS Fibre Channel virtual host bus adapter. Which identifier must be used?

'naa.600a09840691712159764d' is typically an N_Port ID Virtualization (NPIV) World Wide Node Name (WWNN) or a storage device identifier, not a WWPN for a Fibre Channel HBA.

'fe80::314e:4566:8702:bf3d' is an example of an IPv6 link-local address, which is used for IP networking and not for Fibre Channel identification.

'iqn.2021-08.com.acme:3xxx' is an iSCSI Qualified Name (IQN), which is a unique identifier for iSCSI initiators and targets, distinct from Fibre Channel identifiers.

A World Wide Port Name (WWPN) is a unique, 64-bit identifier used to identify a Fibre Channel port, whether physical or virtual, and is conventionally represented as an 8-byte hexadecimal value, often separated by colons. The format '20:00:00:25:B5:97:c3:ac' precisely matches the standard representation of a WWPN, which is essential for Fibre Channel SAN zoning and identification.
