Nokia 4A0-107 Online Questions & Answers

• Question 111:

  Which of the following should be performed if a service provider does not want packets to make use of the shared buffer space when queued?

  A. Set the CBS to 0.
  B. Set the MBS equal to the CBS.
  C. Set the high-priority-only equal to the MBS.
  D. Set the MBS to 0.
  E. Set the high-priority-only to 0.
  B. Set the MBS equal to the CBS.

• Question 112:

  A queue is configured with the following attributes:

  MBS = 10KB CBS = 5KB High-Priority-Only = 30%

  Assume that there is no CBS overbooking and that the slope-policy is disabled. If the current queue depth is 8KB, what will happen to an in-profile packet arriving in the queue?

  A. It will be discarded because the high-priority-only threshold is exceeded.
  B. It will be queued but re-marked as "out-of-profile."
  C. It will be queued in the reserved portion of the buffer pool and remain "in-profile."
  D. It will be queued in the shared portion of the buffer pool but contend for shared buffer space with packets from other queues.
  E. It will be queued in the shared portion of the buffer pool but may be dropped if the buffer utilization exceeds the start-average value of the low slope.
  D. It will be queued in the shared portion of the buffer pool but contend for shared buffer space with packets from other queues.

• Question 113:

  A queue-group template can only contain policers (no queues) when applied under which conditions?

  A. When applied at the FP (Forwarding Path) level for access egress
  B. When applied at an access port for ingress or egress
  C. When applied at the FP (Forwarding Pass) level for access ingress
  D. When applied at the port level for network egress
  C. When applied at the FP (Forwarding Pass) level for access ingress

  A. The DSCP value will be set to af21.
  B. The DSCP value will be set to af23.
  C. The DSCP value will remain as ef.
  D. The EXP value, in the MPLS headers, will be set to 4.
  E. The EXP value, in the MPLS headers, will be set to 3.

• Question 118:

  In which of the following scenarios is the egress port scheduler useful? (Choose two)

  A. A customer is complaining that his VoIP traffic is being dropped even though it is sending the correct DSCP markings. Packets are not being dropped on ingress.
  B. A customer is complaining that his VoIP traffic is being dropped even though it is sending the correct DSCP markings. Packets are being dropped on ingress.
  C. A commercial builder has requested numerous dot1Q epipes, VPRNs, and VPLS services to a business park and is only paying up to a maximum 200Mbps.
  D. An equipment manufacturer has requested a NULL epipe service that will transparently pass dot1Q between the new location and national headquarters.
  A. A customer is complaining that his VoIP traffic is being dropped even though it is sending the correct DSCP markings. Packets are not being dropped on ingress.
  C. A commercial builder has requested numerous dot1Q epipes, VPRNs, and VPLS services to a business park and is only paying up to a maximum 200Mbps.

• Question 119:

  Assume all transmitted frames on a SONET port are 1500 bytes and that the average frame overhead has been configured as 10%. If the total bandwidth of all queues, excluding overhead, needs to be guaranteed at 55 Mbps, how much bandwidth should be configured for the egress port scheduler applied on that port?

  A. 55 Mbps / 1.1 = 50 Mbps
  B. 55 Mbps
  C. 55 Mbps + 55 Mbps * 0.1 / 1.1 = 60 Mbps
