Question 76

Which of the following is a feature of LDP VPLS?

Options:

Service labels are assigned based used on label blocks.

BGP-AD, RADIUS and Management are used for auto-discovery.

Service labels are signaled using MP-BGP.

Hierarchical VPLS is loosely defined in the standards.

Question 77

In the context of hierarchical scheduling, a scheduler is configured with a CIR weight of 0. Which of the following statements is TRUE?

Options:

The scheduler will be allocated its "within CIR" bandwidth before all other children at the same level have received their "within CIR" bandwidth.

The scheduler will be allocated its "within CIR" bandwidth after all other children at the same level have received their "within CIR" bandwidth.

The scheduler will be allocated its "within CIR" bandwidth after all other children at all levels have received their "within CIR" bandwidth.

The scheduler will not be allocated its "within CIR" bandwidth.

Question 78

Click the exhibit button below.

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)

Options:

The DSCP value will be set to af21.

The DSCP value will be set to be.

TheDSCPvaluewillbesettoaf23.

The DSCP value will be set to af 12.

Thedot1pvaluewillbesetto5.

Thedot1pvaluewillbesetto2.

The dot1p value will be set to 3.

Question 79

Click the exhibit button below. Given the scheduler-policy (below), how much bandwidth can the best-effort traffic receive (PIR and CIR) when the ingress rate of each queue is 10Mbps?
