Show Suggested Answer

Suggested Answer: A

Bottom-Up Troubleshooting:The OSI model provides a structured diagnostic approach. Starting at Layer 1 ensures basic physical connectivity issues are ruled out first.

MQTT Relies on IP:MQTT operates at a higher layer of the OSI model, relying on TCP/IP (Layers 4 and 3) for communication. Problems at the physical layer will disrupt everything built upon it.

Checking the Fundamentals:Before investigating complex application issues (MQTT), verify cables, link lights, Wi-Fi signal strength, etc.
