8 queues, regardless of traffic type.

C.

8 unicast and 24 multipoint.

D.

8 unicast and 8 multipoint.

16 queues, distributed as desired.

On the Nokia 7750 SR, which of the following QoS-related policies can be configured on a SAP? (Choose three)

A.

The slope-policy

B.

The SAP-ingress policy

C.

The SAP-egress policy

D.

The network-queue policy

E.

The scheduler-policy

Which of the following are possible criteria for classifying packets at the SAP-ingress? (Choose three)

A.

The EXP bits in the MPLS header.

B.

The packet's source and destination IP addresses.

C.

The service ID of the service to which the SAP belongs.

D.

The dot1p bits in the frame header.

E.

The packet's Ethertype.

Which of the following statements regarding scheduling on the Nokia 7750 SR is TRUE? (Choose two)

A.

When using profile-mode queues, traffic that is marked as in-profile on ingress and scheduled in the above-CIR loop will still be considered as in-profile at egress.

B.

When an HQoS strategy using an egress port-scheduler has been deployed, Tier 1 receives its scheduling rates based on the amount of egress bandwidth available for each forwarding class.

C.

The greater the difference between PIR and CIR rates in a queue, the less likely a CIR will be provided.

D.

Packets scheduled out of high-priority queues in the default scheduler will have a lower chance of packet loss at the expense of incurring a higher probability of delay.

E.

When using priority-mode queues, traffic that is marked as in-profile on ingress and scheduled in the above-CIR loop will be considered as in-profile at egress.

In a Nokia 7750 SR, which of the following QoS policies CANNOT include packet classification criteria?

A.

SAP-ingress

B.

SAP-egress

C.

Network-queue

D.

Network

Which of the following statements BEST describes the IntServ model?

A.

Has the ability to distinguish traffic in 32 different ways.

B.

Uses the RSVP protocol to create microflows through a network.

C.

Has the ability to manually configure foiwarding classes through a network.

D.

Which of the following self-generated traffic applications is considered “protocol” traffic, as opposed to “management” traffic?

A.

BGP

B.

Telnet

C.

ICMP

D.

SNMP

Which of the following statements regarding the egress port scheduler is TRUE?

A.

The egress port scheduler can have up to 17 children spread across 8 levels.

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.

Which of the following statements regarding scheduling are TRUE? (Choose two)

A.

Scheduler policies cannot be children of an egress port-scheduler.

B.

HQoS provides a static method of allocating scheduling resources to each queue and/or child.

C.

Scheduler policies can be applied to the MDA to schedule network ingress traffic.

D.

Every time a scheduler-policy is assigned to a SAP, a new hardware scheduler is created to service the SAP.

E.

A scheduler applied to multiple SAPs within the same service will result in a single hardware scheduler operating across all SAPs within the service.

All interfaces are using their default trust states and MPLS is used as the transport tunnel. The SAP-ingress, SAP-egress, and network QoS policies have been configured as shown below. Assume that the default network-queue policy is used on each router.

At router PE 1, customer traffic is arriving marked with DSCP BE and tagged with a dot1p value of 3.

Based on the configuration shown below for the VPRN service, what will be the DSCP and dot1p marking for the packet egressing at router PE 2? (Choose two)

A.

The DSCP value will be set to af21.

B.

The DSCP value will be set to be.

C.

TheDSCPvaluewillbesettoaf23.

D.

The DSCP value will be set to af 12.

E.

Thedot1pvaluewillbesetto5.

F.

Thedot1pvaluewillbesetto2.

G.

The dot1p value will be set to 3.
