Question 1

Which of the following statements describe the primary objectives of the policing of traffic flows on the Nokia 7750 SR? (Choose two)

AEnsure that traffic flows conform to their traffic profile.

BLog violations of metered traffic flows exceeding the CIR value set on the entity across which the traffic is moving.

CProvide fairness between traffic flows, so that conforming (in-profile) traffic flows are not starved of bandwidth and/or buffer space by non-conforming (out-of-profile) flows.

DMinimize packet loss and reduce end to end latency.

EEnsure that variable latencies do not cluster short bursts of originally conforming packets and render them nonconforming.

Answer : A, C

Question 2

In the context of hierarchical scheduling, a scheduler is configured with a CIR weight of 0. Which of the following statements is TRUE?

AThe scheduler will be allocated its 'within CIR' bandwidth before all other children at the same level have received their 'within CIR' bandwidth.

BThe scheduler will be allocated its 'within CIR' bandwidth after all other children at the same level have received their 'within CIR' bandwidth.

CThe scheduler will be allocated its 'within CIR' bandwidth after all other children at all levels have received their 'within CIR' bandwidth.

DThe scheduler will not be allocated its 'within CIR' bandwidth.

Answer : D

Question 3

Click the exhibit button below. Given the scheduler-policy (below), how much bandwidth can the best-effort traffic receive (PIR and CIR) when the ingress rate of each queue is 10Mbps?

APIR = 4Mbps. CIR = 1Mbps

BPIR = 1Mbps, CIR = 1 Mbps

CPIR = 10Mbps, CIR = 1Mbps

DPIR = 5Mbps, CIR = 1.25Mbps

EPIR = 1.25Mbps, CIR = 1.25Mbps

Answer : B

Question 4

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

ASAP-ingress policy

BSAP-egress policy

CIP-criteria policy

DNetwork-queue policy

ESlope policy

FNetwork policy

Answer : A

Question 5

Which ports on the same MDA share a buffer pool in a Nokia 7750 SR?

AAccess ingress ports

BAccess egress ports

CNetwork ingress ports

DNetwork egress ports

Answer : D

Question 6

Based on queue usage, which of the following QoS-policies when combined will allow queue rates to be dynamically allocated? (Choose two)

AThe slope-policy

BThe SAP-ingress policy

CThe network-queue policy

DThe scheduler-policy

EThe network-policy

FThe WRED-policy

GThe arbitrator-policy

Answer : B, D

Question 7

Refer to the exhibit.

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?

ANC, low

BNC, high

CBE, low

DBE, high

Answer : C
