Question #11 (Topic: Topic 1, Wireless Site Survey
)
During a site survey for a new wireless deployment in a multifloor office building, an engineer must identify sources of interference and ensure optimal AP placement for 5 GHz coverage. While walking the site with a spectrum analyzer, the engineer notices periodic spikes in the noise floor on several channels and inconsistent signal strengths reported by the survey tool, despite visually unobstructed paths.
Which action must the engineer take next to accurately assess and mitigate the Layer 1 interference?
Which action must the engineer take next to accurately assess and mitigate the Layer 1 interference?
A. Use the wireless controller monitoring tools in combination with the site survey tool heatmap output to determine AP locations and capture the Layer 1 spectrum analysis for ongoing analysis.
B. Document the affected channels and locations, then attempt to adjust the channel plan to avoid the frequencies that experience the most interference during initial deployment.
C. Increase the transmit power of all APs to compensate for the signal fluctuations and re-run the survey to verify the visual line-of-sight and signal strength measurements.
D. Use the spectrum analyzer to document the time, frequency, and location of the noise spikes, then correlate them with possible non-Wi-Fi interferes and adjust AP placement accordingly.
Answer: D

Answer: DE
Question #14 (Topic: Topic 1, Wireless Site Survey
)
A surveyor is writing a survey plan for a site that has offices and a warehouse. The engineer must produce a heat map for the entire site, but the warehouse cannot be surveyed with measuring equipment on the Ekahau Site Survey tool.
After surveying the office area, which action must the engineer take to produce a full survey report?
After surveying the office area, which action must the engineer take to produce a full survey report?
A. Do a passive survey for the other areas on the tool.
B. Add simulated APs for the other areas on the tool.
C. Do an active survey for the other areas on the tool.
D. Copy the results to the other areas on the tool.
Answer: B
Question #15 (Topic: Topic 1, Wireless Site Survey
)
A wireless engineer is performing a post verification of a wireless network.
Which two metrics should the engineer verify to ensure that the wireless network is capable of supporting voice services? (Choose two.)
Which two metrics should the engineer verify to ensure that the wireless network is capable of supporting voice services? (Choose two.)
A. The rate of retransmitted packets must be 15 percent or below.
B. The coverage area must have a noise floor that does not exceed -87 dBm.
C. The client device must have at least an -65 dBm RSSI.
D. The rate of retransmitted packets must be 20 percent or below.
E. The client device must have at least an -67 dBm RSSI.
