Question # 106

Five VPLS services have been configured between two PE routers. What is the minimum amount of SDPs that must be configured?

5-one for each service.

2-one in each direction.

10-five in each direction.

None of the above.

Question # 107

Which of the following needs to be considered when designing Ethernet networks with redundancy?

Processing the TTL takes extra time.

MAC learning rate is doubled.

FDB size is doubled.

Requires a protocol to remove loops.

Question # 108

If a management VPLS is administratively disabled what will be the status of the associated user VPLS SAPs?

Regular semantics will apply. It will be as if the SAP doesn ' t belong to a management VPLS.

All user VPLS SAPs will be disabled/pruned.

It is not possible to administratively disable a management VPLS.

Spanning tree will be automatically enabled on the user VPLS SAPs.

Question # 109

Which of the following must be true in order to add a port to a LAG? (Choose 2)

ports must be on the same MDA

ports must have the same speed and duplex settings

auto negotiation must be on

auto negotiation must be off or limited

port must be in access mode only

Question # 110

Which of the following statements relating to VPLS is false?

A VPLS is a multipoint Layer 2 service.

A VPLS allows multiple customer sites to be connected in a single bridged domain.

A VPLS on a single node requires a SDP.

With an IP/MPLS infrastructure, service providers can provide multiple VPLS services over a common IP/MPLS infrastructure.

The VPLS switches traffic based on MAC address associated to the appropriate SAP.

Question # 111

Click on the exhibit below.

Based on the following configuration which VLANs will be managed by the management VPLS?

VLANs 1-4094

VLAN 0

There is not enough information provided

None, this is an invalid configuration

Question # 112

How is MAC learning achieved in traditional Ethernet switches?

As frames leave the switch, the DA is populated into the FDB.

As frames enter the switch, the DA is populated into the FDB.

As frames leave the switch, the SA is populated into the FDB.

As frames enter the switch, the SA is populated into the FDB.

Question # 113

Why is it best practice to set the bridge priority in an STP network? (Choose 2)

This is not a best practice. Any switch can be used as the root bridge.

So that you know which links will be active in your network.

To prevent a new switch from becoming root when added to the network.

To allow all ports on the root switch to become alternate ports.

Question # 114

What are the limitations of a traditional layer 2 switch? (Choose 3}

Isolates collision domains.

Requires layer 2 loop prevention.

Slow response to topology changes.

Limited to 4094 vlans per switch.

Increased flooding.

Question # 115

Click on the exhibit below.

The VPLS service MTU on R2 is 1514 bytes. What must the service MTU be on all other routers participating in the VPLS?

The service MTU must be equal to or smaller than 1514 bytes.

The service MTU must be 1514 bytes.

The service MTU must be equal to or greater than 1514 bytes.

The service MTU can be any value.

Question # 116

In Rapid Spanning Tree Protocol, a Backup Port is on the same switch as a Designated Port?

TRUE

FALSE

Question # 117

Which failure scenario is NOT supported by IEEE 802.lag?

Loss of connectivity.

Unidirectional Loss.

Loop detection.

Merged Services.

End-to-end bit error rates.

Question # 118

Which of the following are required for an operational mesh-sdp binding for bidirectional traffic when signaling is enabled within the SDP? (Choose 3)

LDP must be enabled.

RSVP must be enabled.

An SDP must be configured on the far-end.

Service MTU must match.

SDP ID must match.
