Which benefit does a vehicle data network give over point to point wiring?

  • A.Far fewer conductors carrying far more information
  • B.A faster response, which is the principal reason networks replaced the direct wiring used on earlier vehicles
  • C.Lower cost only
  • D.A reduction in harness weight and complexity together with the sharing of every sensor value between the units

Answer: A

One pair of wires replaces dozens of individual circuits and every module can read every shared value. The last option states both benefits explicitly, which makes it a correct and fuller version of the same answer. Naming what changes and what stays the same is the reliable route through questions of this shape. The order in which the effects act is what decides the outcome, so it is worth establishing first. The quantity that varies and the quantity that does not are worth naming before any substitution is attempted.
