Which of the following is true when describing a link-local address?
Answer: C
Correct answer: These are like private addresses in IPv4 in that they are not meant to be routed.
A link-local address begins FE80::/10, is configured automatically on every IPv6 interface, and is valid only on the link it sits on - no router will forward it. It is what neighbour discovery and the routing protocols use to talk to devices on the same segment, so an interface can be fully operational for routing purposes with no global address at all.
