NetBEUI is NOT routable. To implement use a bridge or brouter. Keeps network cards independent of protocols. Someone who was fooled would go for a,b. Routers eliminate broadcast storms because they do not route packets with unknown destination addresses anywhere.
Bridges simply allow unknown packets to pass through.
You'll see a bus network with 3 terminators attached and it isn't reliable. I don't think that more than two terminators is allowed but you'll have to figure that out for yourself. Mary loses her connection after the holidays.
