Which consequence follows from message based addressing?

  • A.No consequence
  • B.A single broadcast serves every consumer of the value, which is why one wheel speed sensor can serve many systems
  • C.Any node may use a value without the sender knowing
  • D.Each value must be transmitted separately to every node requiring it, which increases the traffic on the bus

Answer: C

Broadcasting by content lets one sensor value serve the brakes, the engine, the transmission and the cluster. The last option gives exactly that example, which makes it a correct and more concrete statement. Naming what changes and what stays the same is the reliable route through questions of this shape. Checking which component actually carries the load settles most questions of this kind at once. A limit that survives making every external component ideal is an intrinsic one, and worth knowing for that reason.
