CWDP-303 Certified Wireless Design Professional Question and Answers

What metric implements the simplest algorithm and lowest accuracy in networks requiring locations?

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?

A controller-based WLAN infrastructure has its controller on a different subnet than its APs. What device must be used to enable any communication between the Controller and the APs?

During an RFP analysis, one of the vendors mentioned that you’ll need to upgrade your Gigabit Ethernet switches to MultiGig switches to ensure support for 802.11ac and 802.11ax, which both offer data rates over 1Gbps. Why is this not sound advice?

When using a predictive design tool, you have selected APs with an antenna gain 3 dBi and set the transmit power of the predicted APs to 25 mW. What should be EIRP of the APs in the design?

What kind of site survey helps you identify if roaming is working as designed?
