Which modulation types are used by OFDM technology? (Choose all that apply.)
- A . QAM
- B . Phase
- C . Frequency
- D . Hopping
You are performing a post-implementation validation survey.
What basic tool can be used to easily locate areas of high co-channel interference?
- A . Throughput tester
- B . Laptop-based spectrum analyzer
- C . Access point spectrum analyzer
- D . Wi-Fi scanner
Your manager asked you to locate a solution that allows for centralized monitoring of WLAN performance over time. He wants a single pane of glass for administration and monitoring of the solution.
What do you recommend?
- A . Laptop-based spectrum analyzers
- B . AP-based spectrum analysis
- C . Overlay WLAN monitoring solution
- D . Laptop-based protocol analyzers
Which of the following are valid calculations when using the rule of 10s and 3s? (Choose all that apply.)
- A . For every 3 dB of gain (relative), double the absolute power (mW).
- B . For every 10 dB of loss (relative), divide the absolute power (mW) by a factor of 2.
- C . For every 10 dB of loss (absolute), divide the relative power (mW) by a factor of 3.
- D . For every 10 mW of loss (relative), multiply the absolute power (dB) by a factor of 10.
- E . For every 10 dB of loss (relative), halve the absolute power (mW).
- F . For every 10 dB of loss (relative), divide the absolute power (mW) by a factor of 10.
What are some popular 802.11 applications used in the healthcare industry? (Choose all that apply.)
- A . VoWiFi
- B . Bridging
- C . RTLS
- D . Patient monitoring
You are troubleshooting a problem with interference from a non-802.11 device. Given that the device is not a WLAN device, you cannot use a protocol analyzer and have chosen to use a spectrum analyzer. You want to view the signal from the interfering device over time to see the activity that is generating.
What common spectrum analyzer view should you use for this analysis?
- A . APs
- B . Waterfall/Spectrogram
- C . Real-time FFT
- D . Clients
The ratio between the maximum peak voltage and minimum voltage on a line is known as what?
- A . Signal flux
- B . Return loss
- C . VSWR
- D . Signal incidents
When the multiple RF signals arrive at a receiver at the same time and are_______with the primary wave, the result can be________of the primary signal.
- A . out of phase, scattering
- B . in phase, intersymbol interference
- C . in phase, attenuation
- D . 180 degrees out of phase, amplification
- E . in phase, cancellation
- F . 180 degrees out of phase, cancellation
802. 11ax (HE) introduces Resource Units that can be used to allow communications with multiple devices at the same time, on the same channel, in the same BSS.
What feature of 802.1 lax provides this functionality?
- A . 6 GHz support
- B . TWT
- C . Wi-Fi-LTE
- D . OFDMA
To establish a 4-mile point-to-point bridge link in the 2.4 GHz ISM band, what factors should be taken under consideration? (Choose all that apply.)
- A . Fresnel zone with 40 percent or less blockage
- B . Earth bulge calculations
- C . Minimum of 16 dBi of passive gain
- D . Proper choice of semidirectional antennas
- E . Proper choice of highly directional antennas
