C.It floods the frame to all PEs participating in the service.

D.It drops the frame.

A.An LSR may answer requests for label mappings immediately, without waiting for a label mapping from the next-hop.

B.An LSR propagates a label mapping downstream for a FEC, only if it has a label mapping for the FEC next-hop.

C.An LSR may advertise label mappings to all peers for which it might be a next-hop for a given FEC.

D.An LSR will only distribute a label for a FEC when it has been requested to do so.

A.The SAP 1/1/1:0 will forward untagged traffic and traffic tagged with VLAN 0

D.The SAP 1/1/1 will forward all traffic transparently.

A.A PE uses a VRF to route traffic to CEs.

B.A PE uses a VRF to maintain forwarding information.

C.Information for VRFs can be advertised between PEs by MP-BGP.

D.A PE uses the same VRF table for all the VPRN services on it.

A.Route distinguishes are used to determine which routes a VPRN should import.

B.Route distinguishes are appended to IPv4 prefixes to form IPv6 prefixes.

C.A route distinguisher combined with an IPv4 prefix produces a VPN-IPv4 prefix.

D.CE routers use a route distinguisher to indicate which VPRN they are associated to.
