Which supply fault mimics a module that has failed entirely?

  • A.A blown fuse or a broken earth, either of which leaves the module silent and appears identical to an internal failure
  • B.An open fuse feeding that module
  • C.A shorted bus line, which would instead disable every module upon the network rather than only the one concerned
  • D.No fault

Answer: B

A silent module is far more often unpowered than broken. The last option names both supply faults explicitly, which makes it a correct and fuller version of the same answer, and both are checked before anything is condemned. Reading the definition literally, rather than recalling a summary, avoids the usual confusion. Naming the cost of a choice alongside its benefit is what turns a fact into a design decision. The shared behaviour explains why these belong together and the differences explain why both exist.
