What is the purpose of a drop profile in a Junos CoS scheduler?

To classify incoming packets based on DSCP.

To set the DSCP value on outgoing packets.

To manage congestion by selectively dropping packets.

To define the transmit rate of a queue.

What is the primary purpose of RED (Random Early Detection) in a Junos CoS drop profile?

To set the MPLS EXP bits on outgoing packets.

To classify packets based on DSCP.

To avoid congestion by dropping packets before the queue is full.

To determine the transmit rate of a queue.

An engineer is configuring CoS on a Juniper router with multiple logical interfaces. The engineer has applied a scheduler map to the physical interface, but the expected queue behavior is not observed on one of the logical interfaces. What is the most likely cause of this issue?

The scheduler map is not applied to the logical interface, and the logical interface is using the default scheduler map.

The drop profile is not applied to the logical interface, causing unexpected drops.

The classifier is not applied to the logical interface, so traffic is not being assigned to the correct forwarding class.

The rewrite rule is not applied to the logical interface, so the DSCP values are not being set correctly.

What is the purpose of a scheduler map in Junos CoS configuration?

To set the MPLS EXP bits on outgoing packets.

To associate schedulers with forwarding classes.

To define the drop profile for each queue.

To classify incoming packets based on DSCP.

Which statement best describes the function of a drop profile in Junos CoS?

It sets the forwarding class for incoming packets.

It defines the transmit rate and buffer size for a queue.

It maps forwarding classes to queues.

It determines the drop probability of packets based on queue depth and loss priority.

Configure or Monitor CoS JN0-664 Practice Questions (Page 3)

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 27 practice questions to prepare you well beyond it.
