If a drop profile has a fill level of 80% and a drop probability of 50%, what happens when the queue reaches 80% occupancy?

Packets are dropped only if they have a high loss priority

Half of the packets are dropped

In a drop profile, what does the 'fill level' represent?

The priority of the queue relative to other queues

The rate at which packets are transmitted from the queue

The maximum number of packets that can be queued

The percentage of queue occupancy at which a certain drop probability applies

How is a drop profile applied to a scheduler node in Junos?

By referencing the drop profile name in the scheduler's drop-profile-map

By using the set class-of-service drop-profiles command on the scheduler

By including the drop profile in the forwarding class definition

By attaching the drop profile directly to the interface

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

To shape traffic by limiting the peak rate of a queue

To prioritize traffic by assigning higher forwarding classes to delay-sensitive packets

To mark packets with a specific forwarding class for downstream devices

To manage congestion by selectively dropping packets based on queue fill level

A network administrator is analyzing the drop behavior of a queue with the following drop profile: ``` interpolate { fill-level [ 30 70 100 ]; drop-probability [ 0 50 100 ]; } ``` The queue fill level is at 85%. What is the drop probability for packets in this queue?
