Which protocol allows Fibre Channel to be transmitted over Ethernet?

HBA
FCoE
iSCSI
SAN

The correct answer is: FCoE

FCoE, or Fibre Channel over Ethernet, is the protocol that enables Fibre Channel data to be transported over Ethernet networks. This integration allows for the consolidation of storage and data traffic onto a single network infrastructure while maintaining the benefits of Fibre Channel, such as high performance and low latency. Using FCoE effectively combines the speed of Fibre Channel with the ubiquity and cost-effectiveness of Ethernet, facilitating data center designs that can be more streamlined and efficient. In a typical scenario, FCoE encapsulates Fibre Channel frames into Ethernet frames, allowing storage area network (SAN) functions to operate over standard Ethernet networks. While HBA (Host Bus Adapter) refers to the hardware component responsible for connecting servers to storage networks, it does not represent a protocol. iSCSI (Internet Small Computer Systems Interface) is another storage networking protocol, but it operates over TCP/IP instead of directly encapsulating Fibre Channel traffic. SAN (Storage Area Network) is a broad term for a network designed to provide access to consolidated, block-level data storage, but again, it does not define the specific protocol that transmits Fibre Channel over Ethernet. Thus, FCoE is the correct answer, as it distinctly facilitates Fibre Channel communications over an Ethernet-based infrastructure.
