Question 74

Click the Exhibit button.

Which two statements are correct about the class-of-service configuration shown in the exhibit? (Choose two.)

The drop probability jumps immediately from 20% to 60% when the queue level reaches 75% full.

To use this drop profile, you reference it in a scheduler.

The drop probability gradually increases from 20% to 60% as the queue level increases from 50% full to 75% full.

To use this drop profile, you apply it directly to an interface.

Correct Answer: B, C

To use the drop profile shown in the exhibit, it must be referenced within a scheduler configuration in Junos OS. This scheduler is then applied to an interface. Moreover, the specified drop-profile configuration indicates that the drop probability gradually increases from 20% to 60% as the queue level transitions from 50% to 75% full, ensuring a smoother and more controlled drop behavior.

Discussion

fukJUNIPEROptions: BC

Correct: BC B. To use this drop profile, you reference it in a scheduler. Correct: In Junos OS, you typically reference a drop-profile within a scheduler configuration. The scheduler is then applied to an interface to control the scheduling and dropping behavior of traffic. So, to use this drop profile, you would reference it in a scheduler configuration. C. The drop probability gradually increases from 20% to 60% as the queue level increases from 50% full to 75% full. Correct: The drop-profile configuration specifies a gradual increase in drop probability from 20% to 60% as the queue level increases from 50% to 75% full. This allows for a more controlled drop behavior as the queue fills up.
