CWNP CWDP-304 Based on Real Exam Environment

ABC Manufacturing has a heavily-used dual-band (2.4 / 5 GHz) WLAN, but sporadic RF interference across the 2.4 GHz band is causing dropped

VoWiFi calls and leading to data connectivity and throughput problems.

In addition to avoiding 2.4 GHz channels and installing a distributed spectrum analyzer to locate RF interference sources, what should the

implementer do to resolve the problem fully?

After deploying a 5 GHz-only WLAN infrastructure in the USA, using 20 MHz channel-widths and all 25 available channels, one of the managers of

the company brings his 802.11n tablet to the office to test the Guest SSID. While testing, there were several spots where we would get poor RSSI

(below -80dBM) or none at all. You checked the WLAN infrastructure and all APs are up and running and you've validated coverage after

deployment. What is causing this issue?

You performed a site survey with two USB Wi-Fi adapters using a special driver written for the site survey software. After deployment, you realized

that the client devices used by your customer are getting lower RSSI values than that shown during your site survey. What is the most likely reason

for this result?

What kind of antenna results in a nearly circular pattern on the azimuth chart but a very flat donut shape on the elevation chart?
