What is a key feature of IEEE 802.11ah that makes it suitable for IoT?

Requires line-of-sight for communication

Support for thousands of devices per access point

Very high data rates exceeding 10 Gbps

A city is deploying smart streetlights that need to communicate over a range of up to 2 km in an urban environment with many buildings. The streetlights are battery-backed and must conserve power. The city is considering IEEE 802.11ah (Wi-Fi HaLow) for this deployment. However, they are concerned about interference from other sub-1 GHz devices. What is the primary trade-off they must consider when using 802.11ah?

It provides deterministic latency but requires complex scheduling.

It operates in the 2.4 GHz band, avoiding interference from other sub-1 GHz devices.

Higher data rates are achieved but with significantly higher power consumption.

Longer range and better penetration come at the cost of lower data rates compared to higher-frequency Wi-Fi.

A convention center is hosting a large event where attendees will use Wi-Fi, Bluetooth beacons for navigation, and a Zigbee network for environmental monitoring. All these systems operate in the 2.4 GHz band. The IT team is experiencing intermittent connectivity issues and suspects interference. They need to implement a solution to improve coexistence. The team has limited budget and cannot replace existing equipment. Which approach is most effective, considering the IEEE 802.19 standard?

Implement IEEE 802.19.1-based coexistence services to coordinate spectrum usage among the different networks

Disable Bluetooth and Zigbee and rely solely on Wi-Fi

Manually configure all devices to use different channels and hope for the best

Upgrade all devices to IEEE 802.15.4e

What is the role of IEEE 802.1AS in an IoT network?

Defining the physical layer for Ethernet

Enabling wireless coexistence in shared spectrum

Providing precise time synchronization across network devices

Managing handovers between heterogeneous 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 44 practice questions to prepare you well beyond it.
