Q1:
How does PBB forward broadcast, unknown-unicast and multicast traffic from a B-VPLS to an l-VPLS?
○
A
The receiving PE checks the l-TAG in the l-SID to determine if there is a local l-VPLS on the node.○
B
The receiving PE checks the l-SID in the l-TAG to determine if there is a local l-VPLS on the node.○
C
The receiving PE checks the service label in the mpls header to determine if there is a local l-VPLS on the node.○
D
The receiving PE checks the multicast B-DA to see if an l-SID has been mapped to the B-DA that matches a local l-VPLS on the node.

Q5:
Click on the exhibit below.
A new router named PE-D is to be directly connected to PE-C and is required to be added to the existing VPLS 300. The design requires the least amount of signaling, the least amount of configuration changes for existing sites and the new site has to have access to all existing sites. How should the new site be added to VPLS 300?
○
A
Configure a mesh-sdp between all existing PE routers and the new PE router○
B
Configure a mesh-sdp between PE-C and PE-D○
C
Configure a spoke-sdp between PE-C and PE-D.○
D
It is not possible to meet the design requirements.
