Click the Exhibit button.
In the exhibit, you see a configuration for CoS. Incoming traffic with specific IP precedence bits
should be mapped to a forwarding class named best-effort. A classifier named normal-traffic is
defined.

What must you add to complete this configuration?

A.
Include the option q-pic-large-buffer under the chassis hierarchy to accommodate the new code
points.

B.
Apply classifier normal traffic to the interface hierarchy under the class-of-service stanza.

C.
Configure a rewrite marker on the ingress Gigabit Ethernet interface.

D.
Add code point values for the expedited-forwarding forwarding class as well as the best-effort
forwarding class.
