  A. 8
  B. 16
  C. 32
  D. 48
  C. 32

• Question 192:

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

  A. When 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.
  B. When 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.
  C. When 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.
  D. When 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.
  A. When 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.

• Question 193:

  Which of the following statements about the bandwidth allocation criteria used by an egress port scheduler is TRUE?

  A. The available bandwidth of the port is divided in a strict priority over its children.
  B. Expedited queues must be serviced before best-effort queues.
  C. Orphaned queues are serviced on the 8th scheduling priority.
  D. The configured CIR dictates the maximum port bandwidth that can be allocated during the within-CIR pass for that level.
  B. Expedited queues must be serviced before best-effort queues.

• Question 194:

  Which of the following statements about behavior aggregate classification is TRUE?

  A. It sets both the forwarding class and the packet's dot1p, lsp-exp, precedence, or dscp field to the same value.
  B. It groups all packets together into a single aggregate stream, and gives all packets the same treatment.
  C. It copies the three most significant bits in the packet's dscp field into the forwarding class.
  D. It assigns a forwarding class based on the packet's dot1p, lsp-exp, precedence, or dscp value.
  B. It groups all packets together into a single aggregate stream, and gives all packets the same treatment.

• Question 195:

  Which of the following statements about the token buckets of a policer is FALSE?

  A. The CIR has no influence on the forwarding rate of the policer traffic.
  B. The CIR influences whether a packet is considered high-profile or low-profile.
  C. The policer discards all incoming packets when PIR bucket reaches the MBS level.
  D. PIR bucket forwards packets that arrive with rates above PIR as out-of-profile.
  A. The CIR has no influence on the forwarding rate of the policer traffic.

• Question 196:

  Which of the following CANNOT be used as external marking bits?

  A. IP Precedence
  B. Dot1p
  C. Forwarding class
  D. EXP

• Question 197:

  In which of the following scenarios is self-generated traffic QoS (sgt-QoS) useful?

  A. EXP markings on transit control traffic are not set correctly.
  B. The priority of all self-generated traffic needs to be lowered to allow all other traffic to take precedence.
  C. The priority of various control packets requires special treatment throughout the network.
  D. The BGP process is consuming too many CPU cycles and is impacting OSPF performance.
  C. The priority of various control packets requires special treatment throughout the network.

• Question 198:
