Which of the following is used to identify ports in a switched Fibre Channel fabric?

IP (Internet Protocol) addresses are used in TCP/IP networks, not for identifying ports within a Fibre Channel fabric.

MAC (Media Access Control) addresses are used for identifying network interfaces in Ethernet networks, not Fibre Channel.

DNS (Domain Name System) translates human-readable names to IP addresses in TCP/IP networks and is not relevant to Fibre Channel port identification.

A World Wide Name (WWN) is a 64-bit unique identifier assigned to Fibre Channel ports and devices, serving a similar function to MAC addresses in Ethernet. These WWNs are essential for the Fibre Channel fabric to identify specific devices and ports for zoning, routing, and overall fabric management.
