   Which statement describes the typical order of configuration for class-of-service (CoS) on a Juniper device?

   • AApply the scheduler map to the interface, then define the classifiers and rewrite rules.
   • BDefine the drop profile, then the scheduler, then the classifier, and finally the forwarding class.
   • CConfigure the interface first, then create the scheduler map and rewrite rules, and finally define the classifiers.
   • DDefine classifiers, forwarding classes, schedulers, and drop profiles, then associate them via scheduler maps and rewrite rules, and finally apply them to interfaces.

   A junior engineer is configuring CoS on a Juniper router for the first time. They have been asked to ensure that voice traffic is placed in a high-priority queue and that the queue is served before other traffic. The engineer has already created a forwarding class named 'voice'. What is the next logical step in the CoS configuration process?

   • AConfigure a rewrite rule to mark voice traffic with a high DSCP value on egress.
   • BApply a classifier to the ingress interface to assign voice traffic to the 'voice' forwarding class.
   • CCreate a scheduler for the 'voice' forwarding class with a strict-high priority and associate it with the forwarding class using a scheduler map.
   • DApply the 'voice' forwarding class directly to the physical interface.
