A service needs to accept frames that have the following: an outer VLAN tag of 200 with an inner VLAN tag of 33; and frames that have an outer VLAN tag of 250 with an inner VLAN tag of 33. What SAP(s) need to be configured?

A.

1/1/1:200.*

B.

1/1/1:*.33

C.

1/1/1:*.*

D.

This requires two SAPs: 1/1/1:200.33 and 1/1/1:250.33

B.

They both support SAP encapsulations of null, dot1Q and Q-in-Q.

C.

They both use SAPs as the demarcation point between the customer and the provider.

D.

MAC addresses are learned by VPLSes, but not by E-pipes.

Which of the following about VPLS MAC learning is FALSE?

A.

The PE routers of the service are responsible for learning MAC addresses.

B.

Flooding ensures that all PEs in a fully-meshed VPLS will learn the source address of all traffic.

C.

MAC learning reduces flooding of frames with previously learned addresses.

D.
