Which three statements are correct regarding Fibre Channel over Ethernet (FCOE)? (Choose three.)

VMware recommends setting Priority-based Flow Control to AUTO on the physical switch so that the switch and the Converged Network Adapter (CNA) can dynamically negotiate lossless Data Center Bridging (DCB) parameters, which is the supported configuration for vSphere FCoE deployments.

Setting PFC to ON (hard-enabled) is not the VMware-recommended setting for FCoE; the AUTO mode is specifically called out in VMware documentation as the required configuration because it enables proper DCB negotiation with the CNA.

Placing multiple FCoE card ports on the same vSwitch is explicitly unsupported - each port requires an isolated vSwitch to maintain separate fabric login sessions and prevent traffic domain collisions.

Each physical port on an FCoE CNA must be assigned to its own dedicated vSwitch because FCoE and standard Ethernet traffic must remain in isolated switching domains; placing multiple CNA ports on a shared vSwitch causes fabric initialization conflicts.

Moving an FCoE adapter port to a different vSwitch requires a full ESXi host reboot to reinitialize the FCoE kernel module and re-establish the fabric login (FLOGI) under the new vSwitch context.
