Which statement describes the purpose of a data flow diagram (DFD) of an IoT system?

  • A DFD depicts the pathways that data will take between different functional components of the system.
  • A DFD uses regular flowchart symbols to depict data flow pathways.
  • A DFD includes entry points into an IoT system, but not the people using those entry points.
  • A DFD uses zones to limit the exposure of different parts of the system to vulnerabilities associated with each zone.

Explanation: Data flow diagrams (DFDs) are useful for visualizing an IoT system. DFDs depict the pathways that data will take between different functional components of the system, including entry points into the system and the devices and people using those entry points. DFDs also label the kind of data flows and the protocols in use.
