What is the most efficient method of implementing IP multicast in a network without using RPs?

• A.Implement source-specific multicast and utilize the functionality of IGMPv3 to replace the RPs.
• B.Implement PIM dense mode multicast to eliminate the need for RPs.
• C.RPs can't be eliminated; they're mandatory in multicast networks.
• D.Implement source-specific multicast and utilize the functionality of IGMPv2 to replace the RPs.

Refer to the exhibit. R2 and R3 are running EBGP and are learning Network A and Network B.
R2 and R3 are also running IBGP to exchange Network A and Network B OSPF is IGP. R2 and R3 are advertising default routes. R1 and R4 can send and receive traffic from Network A and Network B respectively.
However, Network A cannot send traffic to Network B.
How can you solve this problem?

• A.create a tunnel between R2 and R3
• B.create a tunnel between R2 and R4
• C.create static default routes pointing from R1 and R4 to R2 and R3, respectively
• D.convert R3 and R2 to ABRs so that R1 and R4 can choose the closest ABR to exit the network

Refer to the exhibit. Traffic in this network that is destined for 10.1.3.1 arrives at R1. Which path will the traffic take from here and why?

• A.through R3, because it is the lowest cost path
• B.through R2, because it is an intra-area path
• C.through R2, because R3 is in a different autonomous system
• D.through R3, because R1 will only have a summary (type 3) LSA from R2
