Question # 4

When a PE node receives a PBB encapsulated frame on a B-VPLS, how does the PE determine which l-VPLS it belongs to?

A.

The l-TAG in the l-SID is inspected to determine where the frame should be delivered.

B.

When the B-MAC header is stripped the customer MAC address is then looked up in the FDB

C.

The l-SID in the l-TAG is inspected to determine where the frame should be delivered.

D.

The PE inspects the service label in the MPLS header before stripping the B-MAC header.

Question # 5

Click on the exhibit below.

Assume PE-1 has a mesh-sdp configured to every PE node in both Metro networks. What could be done to prevent the bandwidth replication between Metro 1 and Metro 2?

A.

PE-1 must be configured with mesh-SDPs to every node receiving the multicast traffic. There is no way to reduce the replication or bandwidth.

B.

PE nodes in Metro 1 could be configured with mesh-SDPs. PE nodes in Metro 2 would be configured with mesh-SDPs. However, the connection between Metro networks (PE-2 to PE-6) can be configured with a spoke-sdp. This would reduce the replication and bandwidth used on the link between Metro networks. This also reduces the replication required by PE-1.

C.

PE-1 can be configured with spoke-SDPs to every PE node in both Metro networks. This will reduce the bandwidth and replication within the network.

D.

PE nodes in Metro 1 could be configured with spoke-SDPs. PE nodes in Metro 2 would be configured with spoke-SDPs. However, the connection between Metro networks (PE-2 to PE-6) can be configured with a mesh-sdp. This would reduce the replication and bandwidth used on the link between Metro networks. This also reduces the replication required by PE-1.

Question # 6

If the command "disable-learning" has been added at the VPLS level, then MAC entries which have already been learned will not be aged.

A.

TRUE

B.

FALSE

Question # 7

Which element of IEEE 802.1ag is responsible for initiating CFM messages?

A.

MEP

B.

MAP

C.

MIP

D.

MUP

Question # 8

What is the default remote-age timer of a B-VPLS?

A.

The same timer is used in all VPLS types.

B.

Higher than the default timer of an I-VPLS.

C.

Lower than the default timer of an l-VPLS.

D.

The same timer as an l-VPLS.

Question # 9

In IEEE 802.1ag, which two key functions are configured on bridge ports (SAPs and SDPs) to support CFM messages? (Choose 2)

A.

MEP

B.

MAP

C.

MIP

D.

MUP

Question # 10

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

A.

ports must be on the same MDA

B.

ports must have the same speed and duplex settings

C.

auto negotiation must be on

D.

auto negotiation must be off or limited

E.

port must be in access mode only
