In Which Two Ways Is IPv4 and IPv6 Traffic Handled

In which two ways is IPv4 and IPv6 traffic handled in a network design that uses QoS deployment options? (Choose two.)

A) IPv6 and IPv4 traffic is treated in the same way by using a single QoS policy that classifies and matches on both protocols.
B) IPv6 traffic is treated differently than IPv4 by using the flow-label field, which is built into the IPv6 packet header.
C) IPv6 traffic does not require QoS because it uses to the flow-label field, which classifies and matches on the IPv6 protocol.
D) IPv6 traffic is treated differently than IPv4 by using two different QoS policies.
E) IPv6 traffic is treated differently than IPv4 because it uses only the DSCP value and not the IP precedence.
