Ethernet Broadcast

I just took an exam and flubbed a question regarding broadcasting. During the exam I was thinking, "broadcasts are an IP thing since they are sent to 1.1.1.1."
I had forgotten (or never learned) that Ethernet devices can send broadcasts to FF:FF:FF:FF:FF:FF which is the MAC address equivalent of 1.1.1.1.
