A network architect is designing a network for a smart factory and needs to explain to management why the OSI model is useful for troubleshooting even though the factory uses TCP/IP. Which statement best justifies the use of the OSI model in this context?

The OSI model has fewer layers than TCP/IP, making it easier to explain to non-technical management.

The OSI model provides a modular framework that helps isolate problems to specific functions, such as routing or session management.

The OSI model is the protocol stack used by the factory's devices, so it directly maps to the network configuration.

The OSI model is required by international standards for all industrial networks.

Part of the IoT Fundamentals and Networking domain, which makes up ~15% of our current practice bank. EC-Council does not publish an official question count, but from its 120-minute exam (~50–80 total, ~8–12 in this domain), expect 2–3 from this objective — we provide 27 practice questions to prepare you well beyond it.
