A hospital is deploying Wi-Fi 6E access points in a dense patient-care wing. The network team wants to minimize co-channel interference between adjacent APs while maximizing the number of available non-overlapping channels. They plan to use 80 MHz channel widths. Which channel plan should they use?

Use 6 GHz channels 1, 33, 65, and 97 at 80 MHz widths

Use 5 GHz channels 36, 52, 100, and 116 at 80 MHz widths

Use 5 GHz channels 36, 40, 44, and 48 at 80 MHz widths

Use only 2.4 GHz channels 1, 6, and 11 at 20 MHz widths

In RF communication, what does the phase of a signal represent?

The position of the waveform relative to a reference point in time

The strength or power level of the signal

The physical distance between successive wave peaks

The number of cycles the wave completes per second

A warehouse has tall metal shelving units. A wireless site survey shows that a client device receives a strong signal from an AP even though there is no direct line of sight. The signal arrives via multiple paths with different delays. Which propagation mechanism is primarily responsible for this coverage?

Diffraction around the edges of the shelving units

Absorption by the metal shelving, which re-radiates the signal

Reflection off the metal shelving surfaces

Scattering from the rough surfaces of the shelving

Which of the following is an example of non-Wi-Fi interference?

A neighboring access point on the same channel

An access point on an adjacent channel

A Wi-Fi client on the same channel

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.

An engineer is calculating the free space path loss for a link at 5 GHz over a distance of 100 meters. Using the simplified formula FSPL(dB) = 20 log10(d) + 20 log10(f) + 32.44 (with d in km and f in MHz), what is the approximate path loss?
