In an RF link budget, what does the receiver sensitivity value represent?

The transmit power of the receiver's antenna

The minimum signal power required at the receiver to successfully decode the signal

The maximum signal power the receiver can handle without damage

The amount of noise the receiver generates internally

What does the dynamic range of a receiver refer to?

The range of data rates the receiver supports

The range of distances the receiver can communicate over

The range of frequencies the receiver can tune to

The range of signal power levels over which the receiver can operate without distortion or loss of sensitivity

What is the result when two multipath signals arrive at the receiver with opposite phases?

The signal is converted to a different frequency

Destructive interference, reducing signal strength

Constructive interference, increasing signal strength

A user in a conference room reports intermittent Wi-Fi disconnects. The AP is located in the ceiling, and the room has large windows and metal blinds. The signal strength is strong, but the data rate fluctuates dramatically. Which RF phenomenon is most likely causing this issue?

Low SNR due to background noise from the windows

Multipath fading caused by reflections off the metal blinds

Adjacent-channel interference from a nearby AP on channel 6

Co-channel interference from neighboring APs

RF Basics JN0-452 Practice Questions (Page 1)

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.
