What are the main features required of an Industry 4.0 network-?

Question

Options

• ASafety and Profibus compatibility
• Blow latency cybersecurity. convergence
• Cstandardization safety PLC compatibility
• Dsafety IEC 61850 compatibility

• A
  2% (1)
• B
  7% (3)
• C
  5% (2)
• D
  86% (36)

Explanation

Option D is correct because Industry 4.0 networks must prioritize safety (ensuring no harm to personnel, equipment, or processes under all conditions) and IEC 61850 compatibility - the international standard governing communication networks in industrial and power systems that enables interoperability, standardized data modeling, and real-time exchange between multi-vendor devices.

Why the distractors fail:

• A names Profibus, a legacy fieldbus protocol predating Industry 4.0's Ethernet/IP-driven architecture - it's being phased out, not required.
• B lists genuinely relevant concepts (low latency, cybersecurity, convergence), but this combination reflects general IT/OT goals rather than the defining network requirements of Industry 4.0 as defined by the standard referenced in this course.
• C adds PLC compatibility, which is a device-level concern, not a core network feature - and omits the interoperability standard that actually governs industrial communication.

Memory tip: Think "Safe Standards" - Industry 4.0 networks need Safety + a formal Standard (IEC 61850). If an option mentions a legacy protocol (Profibus) or a device type (PLC) as a network requirement, it's a red flag that it's wrong.
