• Question 81:

  A SAP-ingress policy is configured so that ping traffic is classified as FC L1 and mapped to queue 3; however, all traffic is placed in queue 1. What is the most probable reason for this?

  A. The default forwarding class for ICMP traffic is BE and cannot be changed.
  B. The SAP has been shut down.
  C. Queue 3 has no PIR or CIR configured, and thus cannot hold any packets.
  D. The SAP-ingress policy has not been applied to the SAP.
  D. The SAP-ingress policy has not been applied to the SAP.

  A. There are a maximum of 8 levels of priority serviced using a round-robin algorithm.
  B. The default scheduler will spend an equal amount of time in each queue, as long as there is traffic present
  C. The H1 internal forwarding class will receive its CIR before AF traffic.
  D. Orphaned queues will be scheduled out of the BE queue.
  E. A queue servicing EF and AF traffic will require explicit configuration to set the queue to expedited.
  C. The H1 internal forwarding class will receive its CIR before AF traffic.
  E. A queue servicing EF and AF traffic will require explicit configuration to set the queue to expedited.

  B. Multiple egress port schedulers can be assigned to a single port with many HQoS children.
  C. Multiple HQoS policies can be children of a single port scheduler.
  D. Multiple egress port schedulers can be children of a single HQoS scheduler.
  C. Multiple HQoS policies can be children of a single port scheduler.

• Question 88:

  A physical port has three associated buffer pools. Which of the following buffer pool combinations is associated to a physical port?

  A. Access ingress, access egress, network egress
  B. Access ingress, network ingress, network egress
  C. Port ingress, port egress, shared bi-directional

• Question 89:

  Which of the following statements describes an advantage of the DiffServ QoS model over the IntServ QoS model?

  A. DiffServ reserves resources dynamically using the RSVP protocol.
  B. DiffServ only requires packets to be classified into forwarding classes at the first network hop.
  C. DiffServ provides granular differentiation and superior fairness because it processes traffic streams individually.
  D. DiffServ is more scalable it treats traffic streams as aggregates.
  D. DiffServ is more scalable it treats traffic streams as aggregates.

• Question 90:

  Which of the following is NOT an advantage of deploying queue-groups on a network port?

  A. It enables fine-tuned SLA control that is not possible when using a common set of queues for all L2/L3 services.
  B. It enables CFHP and hierarchy scheduling (egress) for each network interface.
  C. It improves scalability by allowing the use of queues instead of the default set of policers used on network egress.
  D. It allows for enforcing bandwidth reservations of the LSPs that are used by the SDPs configured on the network interfaces.
  B. It enables CFHP and hierarchy scheduling (egress) for each network interface.
