Which of the following is NOT an advantage of deploying queue-groups on a network port?

• A.It enables CFHP and hierarchy scheduling (egress) for each network interface.
• B.It improves scalability by allowing the use of queues instead of the default set of policers used on network egress.
• C.It allows for enforcing bandwidth reservations of the LSPs that are used by the SDPs configured on the network interfaces.
• D.It enables fine-tuned SLA control that is not possible when using a common set of queues for all L2/L3 services.

How many tiers of schedulers can be supported in hierarchical scheduling on the Nokia 7750 SR?

• A.8
• B.5
• C.3
• D.6

Click the exhibit button below. Traffic arriving at router PE 1 is marked with a dot1p value of 4. Given the network policies applied on the routers in the diagram below, what is the EXP value of packets arriving at router PE 2?

Note: Only relevant portions of the network policy are shown.

• A.5
• B.2
• C.3
• D.6
• E.None of the above.

When allocating scheduling resources, which of the following statements BEST describes how the egress port scheduler allocates bandwidth?

• A.The egress port scheduler allocates bandwidth based on a WRR distribution method that takes into account the CIR and PIR requested at each level and the max speed, either default or configured, on egress.
• B.The egress port scheduler allocates bandwidth on a first come, first served distribution method that takes into account the total CIR and PIR requested at each level and the max PIR requested from a single level.
• C.The egress port scheduler will limit the bandwidth offered to the egress port based on the over-subscription factor, provisioned under the router interface, while using a WRR scheduler for the remaining bandwidth.
• D.The egress port scheduler takes the ratio of requested bandwidth to total bandwidth request from all children. It allocates bandwidth fairly, using these percentages and not exceeding the egress interface speed.
• E.The egress port scheduler will use the Russian Dolls Method to allocate bandwidth to each level of requested bandwidth. HPO-Only is automatically set to 100%, allowing only high priority traffic to be buffered during congestion.

Which of the following traffic types is typically rate-limited by applying shaping and soft-policing on access ingress?

• A.Real-time
• B.Self-generated
• C.Best-effort
• D.Assured
