An HP Comware switch port is being connected to a server Converged Network Adaptor
(CNA). The CNA and the switch port need to communicate about parameters for various
priority flow control (PFC) and bandwidth control mechanisms. How does the administrator
enable these communications?
A.
Enable PFC globally and then enable PFC on the switch port
B.
Enable LLDP globally and then enable Data Center Bridging eXchange (DCBX) TLVs on
the switch port
C.
Enable the Fibre Channel (FC) fabric port function on the switch port and then set the
port as an F-port.
D.
Enable Ethernet Virtual Bridging (EVB) on the switch port.

B is 100% correct
As per student guide:
Automatic mode is used for links connecting switches to endpoint devices, such as
servers and storage systems. For these links, only the switch need be configured
for PFC. This is because switches use DCBX to exchange configuration
information with the endpoint CNA, which can adopt the switches proposed
configuration.
The first step to enabling DCBX is to ensure that LLDP is enabled globally on the
device.
