When marking traffic for Expedited Forwarding, how does a device that is not capable of
recognizing DSCP interpret the EF binary string 101110?
A.
The device that cannot recognize DSCP will use best effort to forward the packet.
B.
The device that does not recognize DSCP will use 110 as the CoS value and forward the
packet with a CoS of 6.
C.
The first device in the network that does not recognize DSCP will use 110 as the CoS value
and will replace the DSCP value with a CoS of 6 and forward the packet.
D.
The devices in the network that do not recognize DSCP will use the three high-order DSCP bits
as the CoS setting, resulting in a CoS value of 5.
