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?

A. PIR = 4Mbps. CIR = 1Mbps
B. PIR = 1Mbps, CIR = 1 Mbps
C. PIR = 10Mbps, CIR = 1Mbps
D. PIR = 5Mbps, CIR = 1.25Mbps
E. PIR = 1.25Mbps, CIR = 1.25Mbps
Click the exhibit button below. A network operator has configured the SAP-ingress policy below. Ping traffic is expected in queue 3. However, the network operator notices that all traffic is placed in queue 1. What is the most probable reason for this?

A. The default forwarding class for all traffic, including ICMP, is BE, which is placed in queue 1.
B. The SAP has been shut down.
C. The IP-match criteria has been misconfigured for ICMP traffic.
D. Queue 3 has no rate or CIR configured and thus cannot hold any packets.
E. The SAP-ingress policy has not been applied to the SAP.
In which policies, on the Nokia 7750 SR. is classification performed? (Choose three)
A. SAP-ingress policy
B. SAP-egress policy
C. IP-criteria policy
D. Network-queue policy
E. Slope policy
F. Network policy
Which of the following fields is in the MPLS header?
A. 802.1p bits
B. Precedence
C. DSCP
D. EXP
The network QoS policy shown below is applied properly to a Nokia 7750 SR acting as a transit Label Switch Router (LSR) for a given MPLS tunnel. A packet is received inside the MPLS tunnel with EXP=4, dot1p=4, and DSCP=AF. Which forwarding class is assigned to this packet?

A. L2
B. H1
C. AF
D. BE
According to the SAP-ingress QoS policy shown, which of the following statements about processing of the packets by policers 3 and 4 is TRUE?

A. Policer 3 forwards packets as out-of-profile when its PIR bucket has 4000 tokens.
B. Policer 3 starts discarding low-priority packets when its PIR bucket has at least 3000 tokens.
C. Policer 4 forwards all its packets as out-of-profile.
D. Policer 4 starts discarding low-priority packets when its PIR bucket has at least 3000 tokens.
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.
Which of the following features of the Nokia 7750 SR prevents Head of Line blocking in the default queuing model?
A. Every forwarding class can be associated with its own queue without sharing with other forwarding classes.
B. A 3-tier scheduling policy can be applied at SAP-ingress/SAP-egress.
C. For each unicast queue in a SAP-ingress or network-queue policy, there is a separate hardware queue for each destination FFPC.
D. Policing can be deployed instead of queuing at ingress.

In the diagram shown above, applying policing and soft-policing on access ingress is typical for which of the following types of traffic?
A. Real-time
B. Assured
C. Best-effort
D. Self-generated
