Which two devices are required when implementing FCoE? (Choose two.)

A standard Ethernet switch is not sufficient for FCoE because it typically does not provide the lossless transport necessary for Fibre Channel traffic.

FCoE requires a lossless Ethernet switch to ensure that Fibre Channel frames are not dropped, which is critical for the Fibre Channel protocol's reliability and often implemented with Priority Flow Control (PFC).

A Converged Network Adapter (CNA) is a network adapter that combines the functionality of a Host Bus Adapter (HBA) and an Ethernet Network Interface Card (NIC), allowing servers to connect to an FCoE network.

While Fibre Channel switches are used in traditional Fibre Channel SANs, FCoE aims to converge FC traffic onto Ethernet, potentially reducing or eliminating the need for separate FC switches.

A virtual adapter is a software construct within a hypervisor or operating system, not a physical device required for the FCoE fabric connectivity itself.
