A. Each network egress port receives its own buffer pool.

B. Each network ingress port on the same MDA receives its own buffer pool.

C. All SAP-ingress ports on the same MDA share a buffer pool.

D. All the network ingress ports on the same MDA share a buffer pool.

A. Set the MBS to 0.

B. Set the MBS equal to the CBS.

C. Set the high-priority-only equal to the MBS.

D. Set the high-priority-only to 0.

E. Set the CBS to 0.

A. Every time a scheduler-policy is assigned to a SAP, a new hardware scheduler is created to service the SAP.

B. A scheduler applied to multiple SAPs within the same service will result in a single hardware scheduler operating across all SAPs within the service.

C. Scheduler policies can be applied to the MDA to schedule network ingress traffic.

D. HQoS provides a static method of allocating scheduling resources to each queue and/or child.

E. Scheduler policies cannot be children of an egress port-scheduler.

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

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

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

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

A. Best-effort

B. Real-time

C. Assured

D. Self-generated

A. Set the traffic classification of packets to in-profile.

B. Set the high-priority-only value to 0.

C. Set the CIR of queue 3 to a non-zero value corresponding to the customer's expected bandwidth requirements.

D. Map AF traffic to queue 1

E. Set queue 3 to use priority mode.

A. All forwarded packets will be in-profile

B. All forwarded packets will be out-of-profile

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

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

A. 16

B. 72

C. 64

D. 3

E. 56

A. FALSE

B. TRUE

A. Packets processed by the PIR bucket at an average rate above PIR will be forwarded as out-of-profile.

B. The CIR bucket of a policer is the reserved portion of its PIR bucket.

C. When a packet arrives, the PIR bucket depth is checked and the packet is discarded if this bucket is full.

D. The CIR bucket of a policer has two thresholds: CBS and HPO.

A. Packets corresponding to a layer-3 service can be pre-marked on SAP-ingress.

B. Packets corresponding to a layer-3 service can be pre-marked on network-ingress.

C. Packets corresponding to a layer-2 service can be pre-marked on network-ingress.

D. Packets corresponding to a layer-2 service can be pre-marked on SAP-ingress.

A. It enables CFHP and hierarchy scheduling (egress) for each network interface.

B. It enables fine-tuned SLA control that is not possible when using a common set of queues for all L2/L3 services.

C. It allows for enforcing bandwidth reservations of the LSPs that are used by the SDPs configured on the network interfaces.

D. It improves scalability by allowing the use of queues instead of the default set of policers used on network egress.
