1. What factors affect the propagation distance of an RF signal?
A. Antenna gain
B. Receiving station sensitivity
C. Fresnel zone blockage
D. Power over Ethernet (PoE) usage
E. Antenna polarization
F. Link budget calculations
Answer: AC
2. Given: XYZ Corporation is experiencing connectivity problems with their existing building-to-building
bridge link. A brick wall on the roof of one building is partially blocking the Fresnel Zone, and the
connection is dropping many frames. The administrator moves the antenna to an area not obstructed by
the brick wall and then realizes the RF cable cannot reach the new location.
If an RF extension cable is used, what are the likely results?
A. The data throughput rate will increase because VSWR will decrease.
B. The Equivalent Isotropically Radiated Power (EIRP) will decrease.
C. The antenna coverage area will decrease.
D. The return loss will increase unless the impedance of the RF extension cable is equal to 50% of the
antenna impedance.
E. The likelihood of a direct lightning strike will increase, placing the entire WLAN system at risk.
Answer: BC
3. While working on a presentation document in a conference room equipped with a wireless network, you
notice that, as you turn your laptop in different directions, your wireless signal strength changes. What RF
signal property is primarily responsible for this change in signal strength?
A. The RF signal's amplitude is changing due to a change in the visual line-of-sight.
B. The RF signal's wavelength is being affected by varying antenna gain.
C. The RF signal's multipath is changing the amount of RF absorbed by nearby objects.
D. The RF signal's phase is oscillating due to electromagnetic interference (EMI).
A. Antenna gain
