Which of the following statements regarding egress FC and profile over-ride are TRUE? (Choose two)

A. Packets can be classified into 16 different FCs when using priority mode queuing.

B. This feature is available on egress SAPs within any service.

C. MPLS EXP bits can be changed based on multi-field classification.

D. If a Behavior Aggregate (BA) and Multi-field (MF) match occurs, only the MF override parameters will take effect.

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.

Which of the following QoS functions does the slope-policy perform?

A. Classification

B. Marking

C. Queuing

D. Congestion management

E. Scheduling

Which of the following statements regarding scheduling are TRUE? (Choose two)

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

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

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

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

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

Which of the following statements BEST describes the IntServ model?

According to the SAP-egress policy configured and applied, which queue will forwarding class AF's traffic use?

A. Policer 2 on the queue-group Q-Group1 instance 1.

B. Policer 1 on the queue-group Q-Group1 instance 1.

C. The default policer 1.

A. Closest

B. Average

C. Min

D. Max

In the image shown above, the SAP-ingress policy is applied properly to a Nokia 7750 SR. A packet is received from an IP address of 192.168.2.2 with DSCP set to AF. Which forwarding class and priority level is assigned to this packet?

A. NC, low

B. NC, high

C. BE, low

D. BE, high

If packets egressing a SAP do not match any criteria defined in the SAP-egress policy, which forwarding class will these packets be assigned to?

A. The default forwarding class defined in the SAP-egress policy.

B. The forwarding class inherited from network ingress classification.

C. Best Effort.

D. If there is no match, packets will be dropped.

When we select the adaptation rule "min", how are the operational CIR/PIR rates of a queue calculated?

A. The administrative PIR values are ignored and both operational rates are set to the minimum residual rate allowed by the hardware.

B. The administrative PIR value is ignored and both operational rates are set to the administrative CIR value.

C. They are chosen as the largest multiple of the hardware rate step that is less than or equal to the corresponding CIR/PIR administrative value.

D. They are chosen as the smallest multiple of the hardware rate step that is greater than or equal to the corresponding CIR/PIR administrative value.
