Answer: A

Explanation:

The main goal for security of multicast networks is to keep the network running even if there are configuration errors, malfunctions, or network attacks (such as a denial-of-service [DoS] attack from an unknown server). Multicast security involves managing network resources and access control for multiple senders (sources) and receivers by defining what multicast traffic should be allowed in the network. Multicast security must also protect against rogue servers or RPs that should not be in the network. Network resource utilization must be managed; this includes managing multicast state information in the network and services participating in multicast activity.
