Discussion :: IPv6 - IPv6 (Q.No.1)

1. 

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

[A]. Packets addressed to a unicast address are delivered to a single interface.
[B]. Packets are delivered to all interfaces identified by the address. This is also called a one-to-many address.
[C]. Identifies multiple interfaces and is only delivered to 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: Option B

Explanation:

Packets addressed to a multicast address are delivered to all interfaces identified by 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.
