A service provider is deploying a new edge router. They want to ensure that all traffic from a specific customer is placed in a premium forwarding class, regardless of the DSCP markings. The customer's traffic arrives on a specific interface. Which configuration should be used?

Apply a multifield classifier that matches the source IP of the customer and assigns the premium class.

Enable default classification, which will automatically place all customer traffic in the premium class.

Use a rewrite rule to set the DSCP value to premium on all traffic from that customer.

Apply a BA classifier that maps all DSCP values to the premium class on that interface.

In Junos CoS, what is the primary role of a forwarding class?

To encrypt packets before they are transmitted over the network

To filter packets based on source and destination IP addresses

To assign a specific IP precedence value to packets leaving an interface

To determine the scheduling and queuing treatment that packets receive in the forwarding plane
