Which IPv4 multicast technical component measure provides architectural security?

A.
IGMP max groups

B.
access lists

C.
scoped addresses

D.
state limit

Explanation:
The 239.0.0.0/8 range is assigned by RFC 2365 for private use within an organization. From the RFC, packets destined to administratively scoped IPv4 multicast
addresses do not cross administratively defined organizational boundaries, and administratively scoped IPv4 multicast addresses are locally assigned and do not
have to be globally unique. The RFC also discusses structuring the 239.0.0.0/8 range to be loosely similar to the scoped IPv6 multicast address range described in
RFC 1884.
