Q:

Which of the following is true when describing a multicast address?

A) Packets addressed to a multicast address are delivered to a single interface B) packets are delivered to all interfaces identified with the address. This is also called a one-to-many address
C) A multicast address identifies multiple interfaces and is delivered to only one address. This address can also be called one-to-one-of-many D) These addresses are meant for nonrouting purposes,but they are almost globally unique, so it is unlikely they will have an address overlap
 
Answer & Explanation Answer: B) packets are delivered to all interfaces identified with the address. This is also called a one-to-many address

Explanation:

Packets addressed to a multicast address are delivered to all interfaces identified with the multicast address, the same as in IPv4. It is also called a one-to-many address. You can always tell a multicast address in IPv6 because multicast addresses always start with FF.
