Which service permits a control unit to be reprogrammed?

  • A.A programming session entered after a security exchange
  • B.Any diagnostic session, since reprogramming is a standard function available without any restriction whatever
  • C.No service
  • D.A session requiring a seed and key exchange before the memory of the control unit may be erased and rewritten

Answer: A

Security access with a seed and key exchange guards the programming session. The last option describes exactly that mechanism, which makes it a correct and more specific version of the same answer. Naming what changes and what stays the same is the reliable route through questions of this shape. Naming the cost of a choice alongside its benefit is what turns a fact into a design decision. Reading the definition literally, rather than recalling a summary, avoids the usual confusion.
