Which network is increasingly used for high bandwidth vehicle data?

  • A.The controller area network, whose bandwidth has been increased in order to carry the traffic from the camera systems
  • B.The local interconnect network
  • C.A single pair Ethernet variant carrying a hundred megabits or more, used for cameras and driver assistance data
  • D.Automotive Ethernet over a single twisted pair

Answer: D

Single pair automotive Ethernet carries camera and assistance data at a hundred megabits and beyond. The last option describes exactly that, which makes it a correct and more specific version of the same answer. The order in which the effects act is what decides the outcome, so it is worth establishing first. Most errors here come from carrying across a result from a neighbouring case where it does not hold. Framing the question as which quantity the change acts upon makes the answer follow without calculation.
