A company has added a new FCoE storage array to increase the performance of datastore access for end users. This storage array is directly connected to the Cisco Nexus 5672UP switches using four 10G port-channel interfaces. After deployment, the end users fail to access the datastore compared to the older solution. A network engineer verified the port-channel interface and finds that the congestion occurs when PFC frames are generated at the FCoE ingress interface. Which action must be taken to resolve the congestion issue?

A. Reserve bandwidth for FCoE VLAN on the port-channel interface connected with storage.

B. Enable the FCoE class in QoS on Cisco Nexus 5672UP switches.

C. Increase the queuing buffer in the port-channel interface connected to the storage array.

D. Add an additional FCoE VLAN to the SAN network.
