The correct answer is B. Apply classifier normal traffic to the interface hierarchy under the class-of-service stanza. See the full explanation below for the reasoning.
Question
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? {master:0}[edit] user@router# show class-of-service classifiers { inet-precedence normal-traffic { forwarding-class best-effort { loss-priority low code-points [ my1 my2 ]; } } } code-point-aliases { inet-precedence { my1 000; my2 001; cs1 010; cs2 011; cs3 100; cs4 101; cs5 111; cs6 111; } }
Options
- AInclude the option q-pic-large-buffer under the chassis hierarchy to accommodate the new code
- BApply classifier normal traffic to the interface hierarchy under the class-of-service stanza.
- CConfigure a rewrite marker on the ingress Gigabit Ethernet interface.
- DAdd code point values for the expedited-forwarding forwarding class as well as the best- effort
