An industrial IoT network uses IEEE 802.15.4e TSCH to provide deterministic communication for critical control loops. The network operates in a factory with heavy electromagnetic interference from motors and welders. The network administrator notices that some nodes are experiencing high packet loss and missed time slots. They suspect that the TSCH scheduling is not adapting well to the interference. What is the most effective approach to improve reliability in this TSCH network?

Increase the number of retransmissions for all packets to ensure delivery.

Switch to a simpler star topology to reduce the number of hops.

Disable channel hopping to avoid the overhead of switching frequencies.

Implement a centralized scheduling algorithm that dynamically reallocates time slots and channels based on measured link quality.

What is the primary goal of IEEE 802.19 in IoT networks?

To define the physical layer for Ethernet

To minimize interference between different wireless technologies

To provide time synchronization for TSN

To enable seamless handovers between networks

What is the primary role of IEEE 802.15.4 in IoT deployments?

Enabling low-power, low-data-rate communication for battery-operated sensors

Supporting long-range cellular communication for mobile devices

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 44 practice questions to prepare you well beyond it.
