Which of the following devices would allow a storage administrator to implement Fibre Channel over Ethernet (FCoE)?

A Network Interface Card (NIC) is used for traditional Ethernet connectivity and does not natively support Fibre Channel protocols, including FCoE.

A Host Channel Adapter (HCA) is primarily associated with InfiniBand networks, not Fibre Channel or FCoE.

A Host Bus Adapter (HBA) is used for native Fibre Channel connectivity but does not provide the Ethernet functionality required for FCoE.

A Converged Network Adapter (CNA) is specifically designed to handle both traditional Ethernet traffic and Fibre Channel over Ethernet (FCoE) traffic, consolidating the functionality of an HBA and a NIC into a single adapter. This allows servers to connect to both IP-based networks and Fibre Channel storage networks over a single converged network infrastructure.
