Which statement correctly contrasts Fibre Channel over Ethernet (FCoE) and iSCSI?

• A. FCoE runs over Ethernet; iSCSI uses TCP/IP
• B. FCoE requires separate storage protocols; iSCSI does not
• C. FCoE uses USB; iSCSI uses PCIe
• D. FCoE is wireless; iSCSI is wired

Answer: (A)

FCoE and iSCSI differ in how they transport the storage protocol over a network. FCoE carries Fibre Channel frames over Ethernet, so the Fibre Channel storage semantics stay intact while using Ethernet as the transport medium. iSCSI, on the other hand, sends SCSI commands over TCP/IP, leveraging the standard IP network stack for transport. This makes the key distinction clear: FCoE runs Fibre Channel over Ethernet, while iSCSI uses TCP/IP for SCSI over IP networks. The other descriptions don’t fit: FCoE doesn’t require a separate storage protocol to be used beyond Fibre Channel itself, iSCSI doesn’t rely on USB or PCIe, and both are typically wired rather than wireless.
