Bandwidth and replication inefficiency can occur on inter-metro links if there is a lot of multicast traffic

The number of control sessions grows exponentially in a fully meshed network.

Spanning-tree is required to prevent loops when using mesh SDPs on the inter-metro links.

Network touches increase with each node added to the mesh.

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.

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.

The routes from routers R1, R2 and R5.

The routes from routers R1and R2.

The routes from routers R2 and R5.

Two routes are chosen at random and advertised to router R4.

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

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

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

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

The port that the SAP belongs to must have the correct ether type configured.

The SAP must be configured with the right VLAN tag.

The SDP VC type must be configured as type VLAN and the correct vlan-vc-tag must be specified.

All of the above.

The oam mac-ping will fail. The MAC address must be known in the local FDB to be successful.

The request will be flooded and the only response will come from the PE node that has learned the specified MAC address on a local SAP.

The request will be flooded and the CE device with the corresponding MAC will reply.

All nodes will reply because the oam mac-ping is flooded.
