What is an accurate statement about the Data Center Bridging Exchange protocol?

A.
Enables Converged Enhanced Ethernet (CEE) devices to convey and configure their features
with other CEE devices

B.
Creates virtual FCoE links over an existing Ethernet network to transport FC frames over virtual
links independently

C.
Enables an FCoE switch to send signals to other FCoE switches that need to stop or slow down
their transmissions

D.
Enables an FCoE switch to transport both TCP/IP and FC frames over a single virtual FCoE
link

Explanation:

Data Center Brdiging Exchange Protocol (DCBX)
DCBX protocol is a discovery and capability exchange protocol, which helps Converged
Enhanced Ethernet devices to convey and configure their features with the other CEE devices
in the network . DCBX is used to negotiate capabilities between the switches and the adapters,
and it allows the switch to distribute the configuration values to all the attached adapters. This
helps to ensure consistent configuration across the entire network.
