A.Manual route summarization must be done on all the backbone routers to be effective. Manual route summarization is optional on the routers in non-backbone areas.

B.Manual route summarization can only be done on autonomous system border routers.

C.Manual route summarization is done on the ABRs. By default, no route summarization is done and all routes are advertised to all areas.

D.Manual route summarization is done on the ABRs. By default, automatic summarization is done; however, it may not be optimal for all networks.

A.A PE keeps a single FDB for all VPLSes it has.

B.The FDB only stores the MAC addresses of remote sites.

C.Mesh SDPs assist MAC learning by flooding traffic to other mesh SDPs.

D.Frames received on a SAP that are broadcast, multicast or unknown are flooded.

A.PE-1 requires T-LDP sessions to both ABR-1 and ABR-2.

B.ABR-1 requires T-LDP sessions to all ABRs in area 0.

C.PE-1 requires a full mesh of RSVP-TE LSPs to all routers in area 1.

D.PE-1 requires fast reroute enabled on all RSVP-TE LSPs.

A.The LSP is acknowledged by sending a PSNP PDU.

B.The LSP is acknowledged by sending a Hello PDU.

C.LSP are not acknowledged on broadcast links. The DIS sends periodic CSNPs to maintain database synchronization

D.The LSP is acknowledged by sending an LSP PDU.
