IPv6 - Technical MCQs

Q1:

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.

ANS:B - Packets are delivered to all interfaces identified by the address. This is also called a one-to-many address.

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.
