Question 1

According to the configurations shown, which of the following statements about the classification and queuing of self-generated OSPF traffic is TRUE?

AIt will be classified into forwarding class BE and stored in queue 1.

BIt will be classified into forwarding class BE and stored in queue 8.

CIt will be classified into forwarding class NC and stored in queue 1.

DIt will be classified into forwarding class NC and stored in queue 8.

Answer : A

Question 2

Which of the following statements describes a queue's weight parameter that is used in the hierarchical scheduling?

AThe weight specifies the priority of the queue during scheduling up to its CIR.

BThe weight specifies the priority of the queue during scheduling above-CIR, up to its PIR.

CThe weight is used to determine how this queue and other queues or schedulers at the same CIR-level share available CIR bandwidth at that level.

DThe weight is used to determine how this queue and other queues or schedulers at the same level share available above CIR bandwidth at that level.

Answer : D

Question 3

A hierarchical scheduler policy with the shown parameters is configured at a service ingress. If the offered rate of each queue is 10Mbps, what is the operational PIR and CIR for queue 3?

APIR = 5 Mbps, CIR = 0 Mbps

BPIR= 4 Mbps, CIR = 1 Mbps

CPIR= 6 Mbps, CIR = 4 Mbps

DPIR= 6 Mbps, CIR = 1 Mbps

Answer : D

Question 4

Which of the following statements about a queue's rate parameters is FALSE?

AIf CIR = PIR, then all packets will be considered as in-profile.

BCIR can be set to 0.

CCIR can be larger than PIR.

DCIR can be set to 'max'.

Answer : A

Question 5

Which of the following statements about scheduling on the Nokia 7750 SR is FALSE?

AWhen 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.

BWhen 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.

CWhen 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.

DWhen 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.

Answer : A

Question 6

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

APolicer 2 on the queue-group Q-Group1 instance 1.

BPolicer 1 on the queue-group Q-Group1 instance 1.

CThe default policer 1.

DAF traffic is dropped.

Answer : A

Question 7

A queue-group template can contain both queues and policers when applied under which conditions?

AWhen applied at the port level for access ingress.

BWhen applied at the FP (Forwarding Pass) level for access ingress.

CWhen applied at the FP (Forwarding Pass) level for network ingress.

DWhen applied at the port level for network egress.
