Which of the following claims about IPv6 is CORRECT?

Each IPv6 interface is required to have a link-local address: In IPv6, it is mandatory for every interface to have a link-local address. A link-local address is used for communication within the local network segment and is automatically generated by the interface.
IPv6 does not use broadcasts: IPv6 does not use the traditional broadcast mechanism found in IPv4. Instead, IPv6 relies on multicast addressing to achieve similar functionality. Multicast allows a packet to be sent to a select group of hosts, rather than being broadcasted to all hosts on a network segment.
