Questions # 22:

Which of the following statements describes a queue’s weight parameter that is used in the hierarchical scheduling?

Options:
A.

The weight specifies the priority of the queue during scheduling up to its CIR.

B.

The weight specifies the priority of the queue during scheduling above-CIR, up to its PIR.

C.

The weight is used to determine how this queue and other queues or schedulers at the same CIR-level share available CIR bandwidth at that level.

D.

The weight is used to determine how this queue and other queues or schedulers at the same level share available above CIR bandwidth at that level.

3

C.

4

D.

B.

Multiple egress port schedulers can be assigned to a single port with many HQoS children.

C.

Multiple HQoS policies can be children of a single port scheduler.

D.

Multiple egress port schedulers can be children of a single HQoS scheduler.

Questions # 25:

Which of the following statements about the DiffServ and IntServ QoS models is FALSE?

Options:
A.

IntServ uses a protocol like RSVP to provide QoS guarantees on a per-flow basis.

B.

DiffServ groups multiple microflows into bigger streams called macro flows.

C.

Intserv requires that network routers allocate resources for thousands of individual flows.

D.

Diffserv classifies packets into forwarding classes only at the first network hop.

Options:
A.

512 MB ingress, 512 MB egress

B.

256 MB ingress, 256 MB egress

C.

1 GB dynamically allocated between ingress and egress.

D.

768 MB dynamically allocated between ingress and egress.

E.

768 MB, with a minimum of 256 MB ingress and egress, and an additional 256 MB dynamically allocated.

Questions # 29:

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

Options:
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.
