A. The SAP-ingress policy B. The scheduler-policy C. The network-queue policy D. The slope-policy E. The SAP-egress policy

A. Do not change anything; it is already guaranteed to receive its CIR B. Change the CIR-level value for the best-effort queue to 8. C. Change the CIR-weight value of the AF queue to 0. D. Change the CIR-level value for the best-effort queue to 1.

A. 3 B. 5 C. 2 D. 6

A. Egress MDA or ingress network interface B. Egress network interface or ingress MDA C. Ingress SAP or egress SAP D. Egress port or ingress MDA

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

A. A customer is complaining that his VoIP traffic is being dropped even though it is sending the correct DSCP markings. Packets are not being dropped on ingress. B. A customer is complaining that his VoIP traffic is being dropped even though it is sending the correct DSCP markings. Packets are being dropped on ingress. C. A commercial builder has requested numerous dot1Q epipes, VPRNs, and VPLS services to a business park and is only paying up to a maximum 200Mbps. D. An equipment manufacturer has requested a NULL epipe service that will transparently pass dot1Q between the new location and national headquarters.

A. MPLS EXP bits can be changed based on multi-field classification. B. This feature is available on egress SAPs within any service. C. If a Behavior Aggregate (BA) and Multi-field (MF) match occurs, only the MF override parameters will take effect. D. Packets can be classified into 16 different FCs when using priority mode queuing. E. If a Behavior Aggregate (BA) and Multi-field (MF) match occurs, the BA classification can override the forwarding class while the MF classification can override the profile.

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

A. It will be discarded because the high-priority-only threshold is exceeded. B. It will contend for shared buffer space with packets from other queues. C. It will be stored in the queue's reserved buffer space and remain in-profile. D. It will be stored in the queue's reserved buffer space and become out-of-profile.

A. The self-generated packets will be marked with a default DSCP value. B. Ingress self-generated traffic is stored in CPM queues and egress self-generated traffic is stored in IOM queues. C. All self-generated traffic is assigned into forwarding class NC by default. D. The self-generated packets will be marked with default EXP bits.
