Which IPv6 address delivers packets to all nodes in a targeted multicast group?

• A. Multicast address
• B. Global address
• C. Anycast address
• D. Unicast address

Answer: (A)

Multicast addressing in IPv6 is used when you want to reach every member of a specific group. A packet sent to a multicast address is delivered to all devices that have joined that multicast group, so the same data is replicated to every member of the group. These addresses are designated for group delivery and are scoped to various ranges (link-local, site-local, global) as needed. By contrast, a global or unicast address targets a single interface, while an anycast address delivers to the nearest member of a group, not all of them. So to reach all nodes in a targeted multicast group, the appropriate address type is a multicast address.
