Question No: 1

MultipleChoice

Which option best statements BEST describes where shaping mechanisms should be applied?

Options

AOn all ports on the Nokia 7750 SR.

BAt the junction of high-speed to low-speed links or at places of traffic aggregation.

CAt the junction of low-speed to high-speed links or at places of traffic aggregation.

DOn low-speed WAN links.

ENowhere. Shaping is only performed in hardware and serviced in a round-robin.

Question No: 2

MultipleChoice

In which policies, on the Alcatel-Lucent 7750 SR. is classification performed? (Choose three)

Options

ASAP-ingress policy

BSAP-egress policy

CIP-criteria policy

DNetwork-queue policy

ESlope policy

FNetwork policy

Question No: 3

MultipleChoice

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

Options

AReal-time

BAssured

CNon-conforming

DHigh priority

EIn-profile

Question No: 4

MultipleChoice

When deploying an Alcatel-Lucent MPLS network with QoS, how are the EXP bits set?

Options

AThe first 3 bits of the DSCP value are copied directly into the EXP field on the first network egress.

BThe EXP bits are set on the first network egress, based on a combination of the SAP-ingress classification and the network policy applied.

CThe 3 priority bits are copied directly from the dot1p header into the EXP field of the first MPLS header.

DThe EXP bits are set based on a default map that translates DSCP codes into internal forwarding classes on SAP-ingress.

Question No: 5

MultipleChoice

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

Options

AWhen 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.

BWhen 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.

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

DPackets 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.

EWhen 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.

Question No: 6
