What is the primary difference between co-channel and adjacent-channel interference?

Co-channel interference comes from a different Wi-Fi network on the same channel, while adjacent-channel interference comes from a channel that overlaps or is next to the operating channel

Co-channel interference is always stronger than adjacent-channel interference

Co-channel interference is caused by non-Wi-Fi devices, while adjacent-channel interference is caused by Wi-Fi devices

Co-channel interference only affects 2.4 GHz, while adjacent-channel interference only affects 5 GHz

What is the primary factor that causes path loss in free space?

Interference from other signals

Absorption by atmospheric gases

A network admin is troubleshooting a 2.4 GHz network. The AP is on channel 6. The admin detects a strong signal from a neighboring AP on channel 7 and a weaker signal from an AP on channel 1. Which interference type is most likely causing the performance degradation?

Adjacent-channel interference from the AP on channel 7

Co-channel interference from the AP on channel 1

Non-Wi-Fi interference from a Bluetooth device

Multipath interference from reflections in the building

What is the primary effect of scattering on an RF signal?

The signal is redirected in multiple directions, reducing the strength of the main path

The signal is bent around obstacles, extending coverage behind them

The signal is absorbed by the material, converting energy to heat

The signal is amplified by the reflecting surface

Part of the Wi-Fi Fundamentals domain, which makes up ~20% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~7–12 in this domain), expect 1–2 from this objective — we provide 33 practice questions to prepare you well beyond it.
