Which of the following statements regarding scheduling on the Nokia 7750 SR is TRUE? (Choose two)

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

Answer(s): A,C

When deploying a Nokia MPLS network with QoS, how are the EXP bits set?

The first 3 bits of the DSCP value are copied directly into the EXP field on the first network egress.
The EXP bits are set on the first network egress, based on a combination of the SAP-ingress classification and the network policy applied.
The 3 priority bits are copied directly from the dot1p header into the EXP field of the first MPLS header.
The EXP bits are set based on a default map that translates DSCP codes into internal forwarding classes on SAP-ingress.

Answer(s): A,B

Answer(s): A

Which of the following are categories of forwarding classes on the Nokia 7750 SR? (Choose two)

Answer(s): A,D

Which of the following statements describe the operation of WRED on the Nokia 7750 SR? (Choose three)

WRED monitors the shared buffer space utilization over a period of time.
WRED disables the TCP slow-start congestion control mechanism.
WRED uses two configurable slopes for each buffer pool: a high slope and a low slope.
WRED uses the shared buffer utilization, instead of the individual queue depth, to get a better picture of the average resource utilization of the shared buffer space.
WRED polices the shared buffer pool and marks all packets above a certain rate as "discard eligible."

Answer(s): D
