FCoE uses which of the following types of transport?

Fibre Channel is the storage protocol being encapsulated, not the transport mechanism that FCoE uses.

FDDI (Fiber Distributed Data Interface) is an older network technology that is not used as the transport for FCoE.

iSCSI is a separate storage protocol that encapsulates SCSI commands over IP networks, distinct from FCoE which uses Ethernet to encapsulate Fibre Channel.

FCoE utilizes the widely adopted Ethernet protocol as its underlying transport layer, allowing Fibre Channel traffic to converge onto a single, unified Ethernet infrastructure, simplifying network design and reducing cabling.
