Quiz 15B: Install Wireless Networks

Which term describes the weakening of the signal as the distance between devices increases?

• Noise

• Reflection

• Attenuation

• Interference

What is the primary distinction between speed and throughput in wireless performance assessment?

• Speed refers to data rate, while throughput refers to signal strength.

• Speed refers to network layer data transfer, while throughput includes overhead.

• Speed is measured at the physical layer, while throughput is measured at the data link layer.

• Speed is affected by interference, while throughput is affected by attenuation.

Which term describes the strength of the signal sent from the transmitter measured at the receiver on the client end?

• Signal-To-Noise Ratio (SNR)

• Received Signal Strength Indicator (RSSI)

• Channel Utilization

• Effective Isotropic Radiated Power (EIRP)

What is the general range for a good RSSI signal strength?

•   -20 dBm to -30 dBm

• -45 dBm to -55 dBm

• -65 dBm to -80 dBm

• -90 dBm to -100 dBm

Which term describes the comparative strength of the data signal to the background noise?

• Attenuation

• SNR

• Interference

• Channel Utilization

What type of antenna sends and receives signals in all directions more-or-less equally?

• Yagi antenna

• Parabolic antenna

• Unidirectional antenna

• Omnidirectional antenna

What is the unit of measurement for antenna gain?

• dBm

• dBi

• dB

• SNR

Which antenna type is useful for point-to-point wireless bridge connections?

• Yagi antenna

• Parabolic antenna

• Omnidirectional antenna

• Vertical rod antenna

What does EIRP stand for in the context of wireless transmission?

• Effective Isotropic Radiated Power

• Effective Interference Reduction Protocol

• Enhanced Internet Routing Protocol

• Estimated Impact of Radio Propagation

What is the primary goal in minimizing channel overlap in multi-AP sites?

• To maximize co-channel interference

• To optimize CSMA/CA contention

• To reduce adjacent channel interference

• To increase channel utilization
