If the OSPF protocol is used to connect customer edge （CE） routers to service provider edge（PE） routers in the VPN backbone， which two options best describe the use of SHAM links？（）A、A sham-link is created between any twoo VPN sites that belong to the same OSPF area and share an OSPF backdoor linkB、A sham-link is seen as an intra-area link between PE routers，an OSPF adjacency is created and data base is exchangedC、A SHAM link is created between two directly connected PE routers so that it is preferred over the low speed backdoor doorD、A SHAM link is part of OSPF network of MPLS-VPN provider

Which three are benefits of IS - IS over OSPF?（）A、supports route tagsB、supports more routers in an areaC、does not require Hello packets to establish neighbor relationshipsD、produces fewer link state advertisements for a given networkE、supports network layer protocols other than IPF、requires fewer neighbor relationships in a broadcast multiaccess network
考题
Which four statements about the Carrier Supporting Carrier （CSC） feature are true？ （）A、MPLS is required between the PE and CE routers that connect the backbone carrier to the customer carrier.B、The backbone carrier must enable the PE router to check that the packets it receives from the CErouter contain only the labels that the PE router advertised to the CE router.C、Every packet that crosses the backbone carrier must be encapsulated so that the packet includes MPLS labelsD、AII PE routers that link the backbone carrier to the customer carrier must run Route Target Rewrite.E、Arouting protocol is required between the PE and CE routers that connect the backbone carrierto thecustomer carrier. The routing protocol enables the customer carrier to exchange IGP routing information with the backbone carrier.
