All links inside the network are configured at a default cost of one inside the fully converged OSPF domain.
Given the configuration from XR1, which interface does traffic from XR1 that is destined to the loopback interface of XR6 select for the exiting interface?

• A.Interface GigabitElhemet 0/0. The tie breaker of the node index priority is lower and trumps the path cost.
• B.Interface GigabitEthernet 0/0. The tier breaker of the path cost being lower. The node index priority does not impact this selection process.
• C.Interface GigabitEthernet 0/1. The tie breaker of the node index priority is lower and trumps the path cost.
• D.Interface GigabitEthernet 0/1. The tie breaker of the path cost being lower. The node index priority does not impact this selection process.

Which two functions are supported for BGP extension MP-BGP for IP multicasting? (Choose two.)

• A.MP-BGP is useful when a link dedicated to multicast and unicast traffic is desired.
• B.MP-BGP carries single sets of routes for unicast routing and multicast routing.
• C.MP-BGP is an enhanced BGP that carries routing information for multiple network layer protocols and IP multicast routes.
• D.A network can support incongruent unicast and multicast topologies.
• E.A network can support congruent unicast and multicast topologies.
