Assume all transmitted frames on a SONET port are 1500 bytes and that the average frame overhead has been configured as 10%. If the total bandwidth of all queues, excluding overhead, needs to be guaranteed at 55 Mbps, how much bandwidth should be configured for the egress port scheduler applied on that port?

55 Mbps / 1.1 = 50 Mbps

55 Mbps

55 Mbps + 55 Mbps * 0.1 / 1.1 = 60 Mbps

55 Mbps * 1.1 = 60.5 Mbps

A port scheduler can be implemented on an access ingress port.

A port scheduler can be implemented without HQoS on an access egress port.

A port scheduler can be implemented on a network ingress port.

Question 216

Which of the following statements about the default scheduler in the Nokia 7750 SR is TRUE?

A queue will be serviced as expedited if all of the forwarding classes mapped to it are expedited, regardless of its configured type.

A queue will be serviced as best-effort if all of the forwarding classes mapped to it are best-effort, regardless of its configured type.

A queue will be serviced as expedited if at least one of the forwarding classes mapped to it is expedited, regardless of its configured type.

A queue will be serviced as expedited if its type is configured as expedited, regardless of the forwarding classes mapped to it.

Question 217

Refer to the exhibit.

Given the scheduler-policy parameters shown, and assuming the offered rate of each queue is 10 Mbps, what are the operational PIR and CIR for queue 3?

PIR = 4 Mbps, CIR = 1 Mbps

PIR = 1 Mbps, CIR = 1 Mbps

PIR = 10 Mbps, CIR = 1 Mbps

PIR = 5 Mbps, CIR = 1.25 Mbps

PIR = 1.25 Mbps, CIR = 1.25 Mbps
