CWNP CWDP-304 - Certified Wireless Design Professional

You told your customer that multipath fading may be mitigated simply by moving one or both of the receivers antennas a small amount, usually by

one to four wavelengths away from its original position. Your customer is prepared to make the change, but does not know the wavelength for

802.11ac.

What is the approximate wavelength of an 802.11ac radio wave?

If you choose to recommend dynamic channel assignment for the APs in your WLAN design what action should you also recommend'?

Location technology (RTLS) can use which of the following methods?(Choose all that apply.)

Response:

You are validating association capabilities from clients to an 802.1X/EAP secure SSID. The RADIUS server's IP address is 10.100.50.25 and the

default RADIUS authentication port is used. When testing them, none of the clients are able to associate to the SSID. Troubleshooting the WLAN

infrastructure, you found out that the server is up and the RADIUS service is up as well, but the authenticator is not able to communicate properly

with the server. What's your next troubleshooting step?

What is the minimum PoE budget needed on a switch to support 6 (six) APs that can only be powered using IEEE 802.3at if no other details are

provided?

You must perform a site survey that defines signal strength, throughput and latency What kind of survey should you perform?

As a device starts to shift to lower PHY rates, what factors usually influence a device decision to shift to lower PHY rates?(Choose all that apply.)

Modulation can be defined as:

Response:

Your customer is using PSK as their only authentication. They have an industry requirement to move to a stronger solution. Your recommendation

is to move to a certificate-based type of authentication where both the client and server require certificates. Which EAP type would be the best fit?

When designing a WLAN to support voice in a large office, which design element is of the highest concern for performance?
