Question 36

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?

  1. PIR = 4Mbps. CIR = 1Mbps
  2. PIR = 1Mbps, CIR = 1 Mbps
  3. PIR = 10Mbps, CIR = 1Mbps
  4. PIR = 5Mbps, CIR = 1.25Mbps
  5. PIR = 1.25Mbps, CIR = 1.25Mbps

Question 37

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

  1. The scheduler will be allocated its "within CIR" bandwidth before all other children at the same level have received their "within CIR" bandwidth.
  2. The scheduler will be allocated its "within CIR" bandwidth after all other children at the same level have received their "within CIR" bandwidth.
  3. The scheduler will be allocated its "within CIR" bandwidth after all other children at all levels have received their "within CIR" bandwidth.
  4. The scheduler will not be allocated its "within CIR" bandwidth.

Question 38

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

  1. Ensure that traffic flows conform to their traffic profile.
  2. Log violations of metered traffic flows exceeding the CIR value set on the entity across which the traffic is moving.
  3. Provide 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.
  4. Minimize packet loss and reduce end to end latency.
  5. Ensure that variable latencies do not cluster short bursts of originally conforming packets and render them nonconforming.

Question 39

Which of the following entities can scheduler policies be applied to? (Choose two)

  1. Network ingress port
  2. Epipe ingress SAP
  3. ES egress SAP
  4. Ingress MDA
  5. VPRN ingress interface
  6. Shared buffer space

Question 40

It is necessary for Tier 1 schedulers to obtain bandwidth from a higher tier scheduler.

  1. TRUE
  2. FALSE
