Question

What is a difference between an IPv6 multicast address and an IPv6 anycast address?

Options

AAn IPv6 multicast address uses the prefix 2002::/15 and forwards to one destination, and an IPv6
BA packet sent to an IPv6 multicast address is delivered to one or more destinations at once, but a
CIPV6 multicast addresses are used to transition from IPv4 to IPv6, and IPv6 anycast addresses
DAn IPV6 multicast address is assigned to numerous interfaces within a subnet, but an IPv6

Explanation

IPv6 multicast delivers packets to multiple destinations simultaneously, whereas IPv6 anycast delivers to the closest single destination among a group.

Common mistakes.

A. The prefix 2002::/15 is for 6to4 transition, not a general IPv6 multicast address, and multicast delivers to multiple, not a single, destination.
C. IPv6 multicast addresses are used for group communication, not specifically for IPv4 to IPv6 transition mechanisms.
D. While multicast addresses are assigned to numerous interfaces, this choice does not provide a complete and accurate distinction from anycast as clearly as option B.
