The configuration in the exhibit is associated with which class of service component? ... if-exceeding { bandwidth-limit 1m; burst-size-limit 3k; } then discard;

Classification is the process of identifying and marking traffic, not defining limits and actions for exceeding them.

Policing involves setting rate limits on traffic (like `bandwidth-limit` and `burst-size-limit`) and taking an action, such as `discard`, when those limits are exceeded. This is a direct implementation of a policer to manage traffic flow.

Queuing involves placing packets into different queues for prioritization and scheduling, which is distinct from rate limiting and discarding excess traffic.

Scheduling determines the order and rate at which packets are transmitted from queues, rather than directly limiting the incoming rate and discarding excess traffic.
