Q1. Based on the following configuration: 

Which two statements about multicast VPN configuration are true? (Choose two.) 

A. The multicast tree is created based only on the existence of active sources or receivers behind PEs in the ABC VRF. 

B. The service provider core network is required to support SSM. 

C. Multicast needs to be enabled only on ABC VRF and is tunneled to participating PE routers in the ABC VRF. 

D. The SP core network is required in order to enable the BGP Multicast Address Family on all peering. 

E. Multicast is required for the core network in addition to the ABC VRF. 

F. The multicast tree exists regardless of whether there are any active sources or receivers in the ABC VRF.

Q8. Two Service Providers are beginning a merger between AS boundaries to provide MPLS-enabled services between their networks. Customers are using both Service Providers for services and, under certain circumstances; there are requirements to extend Layer 2 VPN circuits between each provider. The providers are in the process of completing the technical merger. However, the MPLS is not supported between the providers. Which action allows MPLS Layer 2 VPN circuits to be built over the inter-AS link? 

A. Create a GRE tunnel with the mpls ip command between ASBRs. 

B. Create Layer 2 VPN peerings between PE routers from each provider. 

C. Create a VPNv4 peering between ASBRs to advertise labels between each provider. 

D. Create a sham link between ASBR routers to enable a superbackbone peering for Layer 2 VPN signaling.

Q10. Refer to the exhibit. 

OSPF is already running with the default OSPF parameters. R1 has added a new subnet (loopback 11). What will occur in regards to SPT computing on R2 router? 

A. Adding ispf command on R2 router, the entire SPT will be computed on R2 router. 

B. Because 10.11.11.11/32 prefix information will be in a LSA type 3 on R2 router's OSPF database, R2 router will run partial SPF computation. 

C. Adding ispf command on R2 router, R2 router will recompute only the affected part of tree. 

D. Because 10.11.11.11/32 prefix will be a LSA type 1 on R2 router's OSPF database. R2 router will always run a full SPF computation, even though an OSPF optimization is applied on R2 router.
