A service provider is designing a CoS policy for a new internet service. The policy must ensure that premium customers receive a higher share of bandwidth during congestion. The engineer plans to use forwarding classes and queues to implement this. Which configuration element is responsible for determining how much bandwidth each queue receives?

The scheduler configuration, which defines the transmit rate and buffer size for each queue.

The rewrite rule configuration, which sets the CoS bits on outgoing packets.

The classifier configuration, which maps packets to forwarding classes.

The policer configuration, which limits the rate of traffic entering the queue.

Part of the Class of Service (CoS) domain, which makes up ~16% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~6–10 in this domain), expect 1–1 from this objective — we provide 20 practice questions to prepare you well beyond it.
