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)

  1. All out-of-profile traffic will be dropped before any in-profile is dropped.
  2. The time average factor of 0 will discard all packets arriving in the shared buffer pool.
  3. When the shared buffer utilization reaches 51%, in-profile packets might be dropped.
  4. The highest probability with which an out-of-profile packet can be dropped is 20%.
  5. 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.

Answer(s): A,C,E

Which of the following are entities of the Nokia 7750 SR on which you can NOT apply a network- queue policy? (Choose three)

  1. Router interfaces
  2. Ingress MDA
  3. Ingress Ethernet network ports
  4. Egress Ethernet network ports
  5. Service SAPs

Answer(s): A,C,E



When allocating scheduling resources, which of the following statements BEST describes how the egress port scheduler allocates bandwidth?

  1. The egress port scheduler takes the ratio of requested bandwidth to total bandwidth request from all children. It allocates bandwidth fairly, using these percentages and not exceeding the egress interface speed.
  2. The egress port scheduler allocates bandwidth based on a WRR distribution method that takes into account the CIR and PIR requested at each level and the max speed, either default or configured, on egress.
  3. The egress port scheduler allocates bandwidth on a first come, first served distribution method that takes into account the total CIR and PIR requested at each level and the max PIR requested from a single level.
  4. The egress port scheduler will limit the bandwidth offered to the egress port based on the over- subscription factor, provisioned under the router interface, while using a WRR scheduler for the remaining bandwidth.
  5. The egress port scheduler will use the Russian Dolls Method to allocate bandwidth to each level of requested bandwidth. HPO-Only is automatically set to 100%, allowing only high priority traffic to be buffered during congestion.

Answer(s): B
