The broadcast generates an interrupt though. Broadcast domains are not
relevant to the question. Get them out of your head. ;-) The only things
that can stop broadcasts are routers and VLANs. It has nothing to do with
frame types.

That's not what is normally meant by a broadcast domain.
Any station on the same switched or repeated network hears each of the
broadcasts. If the device were on the other side of a router or in a
different VLAN, it wouldn't hear them. The device would be in a different
broadcast domain.
