Question

In an FCoE environment, for which two categories of data must an interface implementing the PAUSE mechanism always provide sufficient ingress buffering?

Choose two

A frames that were sent with high credit
B frames that were sent on the link but not yet received
C frames that were processed and transmitted by the transmitter after the PAUSE frame left the sender
D frames that were processed and transmitted by the transmitter before the PAUSE frame left the sender
E frames that were sent on the link and received

Explanation

A PAUSE mechanism has propagation and reaction delay. Ingress buffering must accommodate frames already on the link but not yet received, as well as frames the peer processes and transmits after the PAUSE frame has left the sender but before the peer acts on it. This is the basis for provisioning buffer capacity for twice the link distance in multihop FCoE.
