Which of the following statements regarding scheduling on the Nokia 7750 SR is TRUE? (Choose two)

A.

When using profile-mode queues, traffic that is marked as in-profile on ingress and scheduled in the above-CIR loop will still be considered as in-profile at egress.

B.

When an HQoS strategy using an egress port-scheduler has been deployed, Tier 1 receives its scheduling rates based on the amount of egress bandwidth available for each forwarding class.

C.

The greater the difference between PIR and CIR rates in a queue, the less likely a CIR will be provided.

D.

Packets scheduled out of high-priority queues in the default scheduler will have a lower chance of packet loss at the expense of incurring a higher probability of delay.

E.

When using priority-mode queues, traffic that is marked as in-profile on ingress and scheduled in the above-CIR loop will be considered as in-profile at egress.

Which of the following is an advantage of using queue-groups on a service SAP?

C.

It allows a separate set of queues/policers for each VLAN on a port.

Click the exhibit button below. Given that the slope-policy (below) has been enabled and applied on a network port, which of the following statements are TRUE? (Choose three)

A.

All out-of-profile traffic will be dropped before any in-profile is dropped.

B.

The time average factor of 0 will discard all packets arriving in the shared buffer pool.

C.

When the shared buffer utilization reaches 51%, in-profile packets might be dropped.

D.

The highest probability with which an out-of-profile packet can be dropped is 20%.

E.

When an in-profile packet arrives and the shared buffer utilization is at 69%, the packet will have approximately a 60% likelihood of being discarded.

D.

768 MB dynamically allocated between ingress and egress.

E.

768 MB, with a minimum of 256 MB ingress and egress, and an additional 256 MB dynamically allocated.
