That's hybrid. And that term has no technical meaning--it comes from
Cisco marketing speak.

"other" implies that EIGRP is also a link state protocol. It is not.

It uses a hello subprotocol, which is not inherently LS or DV. The
LS or DV algorithms are used in route computation, which is a
function different than topology discovery.

Are you deliberately trolling to irritate people? Incidentally, it
appears that the test taking skills do not include spelling, assuming
you hold certifications.
