Fe80::F856:02AA is a valid IPv6 address used for which scope?

Explanation:
IPv6 uses prefix ranges to define how far an address can be used. A link-local address is limited to the local network segment and never routes beyond the immediate link. It uses the FE80::/10 prefix, so any address that starts with FE80 falls into this scope. Fe80::F856:02AA is therefore a link-local address, which is automatically configured on each IPv6-enabled interface and used for local communication like neighbor discovery and reaching routers on the same link. It won’t be routable to other networks. Global unicast addresses start with 2000::/3, multicast starts with FF00::/8, and reserved prefixes cover other special purposes, so this address isn’t any of those.
