Which of the following about scheduling is TRUE?

• A.A scheduler policy applied to multiple SAPs within the same service will result in a single hardware scheduler operating across all SAPs within the service.
• B.HQoS scheduler policies can be applied to an MDA to schedule network ingress traffic.
• C.HQoS schedulers provide a dynamic method of allocating scheduling resources to queues.
• D.HQoS schedulers cannot be children of an egress port-scheduler.

Which of the following BEST describes a SAP when regarding QoS?

• A.A point in the network where QoS parameters are discarded in favor of lower-level hardware queuing functions, such as LLI (Link Layer Interleave).
• B.A point in the network where EXP bits can be mapped to one of eight predefined FCs, each one with its own queue.
• C.A point at which the initial classification of customer traffic occurs.
• D.A point in the network where traffic flows from multiple different services are queued together, based on forwarding class.
• E.A logical point in a service tunnel where all of customer traffic is aggregated.

What can be learned from the output of the command "show pools 1/2/2 network-egress" on the GigE port?

• A.All incoming packets belonging to forwarding class "l2" are stored in the reserved buffer space.
• B.In-profile packets in the shared buffer space are being dropped.
• C.All incoming packets belonging to forwarding class "l1" are stored in the reserved buffer space.
• D.All incoming packets belonging to forwarding class "af" are stored in the reserved buffer space.

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.BE
• B.L2
• C.H1
• D.AF

A queue-group template can contain both queues and policers when applied under which conditions?

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