Question 1

Which priority-mode queue parameter may influence both the profile marking, and scheduling priority of a queue?

APIR

BCIR

CMBS

Dburst-limit

Answer : C

Question 2

Click the exhibit button below.

Based on the configuration of the network policy (below), what will be the forwarding class associated with a MPLS encapsulated customer packet that arrives on a dotlQ encapsulated network port 1/1/4:1 on P1 with the following characteristics:

EXP value = 6

DSCP value = cs1

Dot1pvalue = 3

AEF

BH1

CL1

DH2

EL2

Answer : D

Question 3

Which of the following statements regarding the default scheduler in the Alcatel-Lucent 7750 SR are TRUE? (Choose two)

AThere are a maximum of 8 levels of priority serviced using a round-robin algorithm.

BThe default scheduler will spend an equal amount of time in each queue, as long as there is traffic present

CThe H1 internal forwarding class will receive its CIR before AF traffic.

DOrphaned queues will be scheduled out of the BE queue.

EA queue servicing EF and AF traffic will require explicit configuration to set the queue to expedited.

Answer : C, E

Question 4

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

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

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

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

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

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

Answer : C, D

Question 5

Click the exhibit button below. A network operator has configured a network-queue policy to map forwarding classes to queues, as shown in the exhibit below. Based on the default scheduling behavior of the Alcatel-Lucent 7750 SR, in which order will packets be serviced?

AAll in-profile packets in round-robin, then all out-of-profile packets in biased round-robin.

BIn-profile EF packets, then in-profile H2 packets, then in-profile AF packets, then out-of-profile EF packets, then out-of-profile H2 and AF packets, and then out-of-profile BE packets.

CIn-profile EF, H2 and AF packets, then out-of-profile H2, AF and BE packets in biased round-robin.

DIn-profile EF packets, then in-profile H2 and AF packets, then out-of-profile H2, AF and BE packets in biased round-robin.

EIn-profile EF and H2 packets, then in-profile AF packets, then out-of-profile H2, AF and BE packets in biased round-robin.

Answer : D

Question 6

On the Alcatel-Lucent 7750 SR, what is the maximum number of queues that a single SAP-ingress policy can support in a VPLS?

A16

C32

D48

E56

Answer : C

Question 7

Which of the following statements are TRUE regarding the PE device in a QoS enabled network? (Choose two)

AA device that provides no differentiation between customer traffic flows.

BA device that classifies and marks customer traffic.

CA device that uses MPLS EXP bits to differentiate between traffic flows.

DA device that creates macroflows towards the core from multiple customer sites.

EA device that passes macroflows while optionally changing QoS markings.

Answer : B, D
