How many tiers of schedulers can be supported in hierarchical scheduling on the Nokia 7750 SR?

Question 201

A profile-mode queue is configured with the following attributes: MBS = 10 KB, CBS = 5 KB and High-Priority- Only = 30%. Assume there is no CBS overbooking, and the slope-policy is disabled. If the current queue depth is 8 KB, what will happen to an in-profile packet?

It will be discarded because the high-priority-only threshold is exceeded.

It will be stored in the queue's reserved buffer space and become out-of-profile.

It will be stored in the queue's reserved buffer space and remain in-profile.

It will contend for shared buffer space with packets from other queues.

Question 202

Refer to the exhibit.

According to the SAP-ingress QoS policy shown, which of the following statements about packets processed by policer 6 is TRUE?

All forwarded packets will be in-profile

Packets forwarded above CIR will be marked out-of-profile and the rest will be in-profile

Excess packets that arrive within a burst larger than CBS will be forwarded as out-of-profile

All forwarded packets will be out-of-profile

Question 207

Which of the following is an example of something that CAN be done with hierarchical policing (CFHP) but CANNOT be done with standalone policers?

Limiting the maximum forwarding rate of each individual policer and, at the same time, marking, packets as in-profile or out-of-profile.

Putting packets in a buffer as they are received, and marking packets as in-profile or out-of-profile as they are removed from the buffer.

Rate-limiting the collective output of several policers, and to reallocate bandwidth that is not utilized by some policers to other policers that need to use it.

Rate-limiting the collective output of several policers towards each egress FFPC, while maintaining control of the maximum overall forwarding rate.

Question 208

When we select the adaptation rule ''min'', how are the operational CIR/PIR rates of a queue calculated?

The administrative PIR values are ignored and both operational rates are set to the minimum residual rate allowed by the hardware.

The administrative PIR value is ignored and both operational rates are set to the administrative CIR value.

They are chosen as the largest multiple of the hardware rate step that is less than or equal to the corresponding CIR/PIR administrative value.

They are chosen as the smallest multiple of the hardware rate step that is greater than or equal to the corresponding CIR/PIR administrative value.
