Refer to the Exhibit.
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.
