Selected Answer: B

The technology that provides a simplified and controlled approach to interconnecting multicast domains across multiple autonomous systems is MSDP (Multicast Source Discovery Protocol). MSDP is specifically designed for inter-domain multicast routing and allows autonomous systems to share information about active multicast sources. MSDP enables the exchange of multicast source information between the border routers of different domains. It allows receivers in one domain to learn about multicast sources in another domain, enabling multicast traffic to be distributed across multiple domains in a controlled and coordinated manner.

B correct , MSDP provides inter-domain access to multicast sources in all domains by enabling all Rendezvous Points (RPs) to discover multicast sources outside of their domains.
