CWDP-303 Online Practice Questions and Answers

A business traveler from North America is in Europe. The hotel only provides coverage in 2.4 GHz. The traveler connects to the hotel's SSID and notices an AP in the hotel room. However, the laptop reports a very low RSSI when connected. The traveler does not have the same problem when connecting in the lobby. What would be the most likely cause of the low RSSI in the hotel room?

A. The AP in the room is using ZigBee instead of Wi-Fi.

B. The AP in the room is transmitting on channel 13 and the traveler associated to a non-channel 13 AP located elsewhere.

C. The switchport that the AP is connected to is only capable of transmitting at 10 Mbps.

D. The AP in the room is using Bluetooth instead of Wi-Fi.

A customer is acquiring a new VoWLAN system to replace their existing wired phone system. When reading about his system's requirements, you learned that is requires 25 db of SNR to work as expected. After surveying the environment, you discovered that the noise floor is -88 dBm. What should be the minimum RSSI value to meet the system's requirements?

A. -70 dBm

B. -67 dBm

C. -65 dBm

D. -63 dBm

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?

A. 11 dBm

B. 6.25 mW

C. 125 mW D. 17 dBm

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?

A. USB Wi-Fi adapters designed for site surveys may have better sensitivity than regular Wi-Fi cards installed in client devices.

B. The transmit power on the APs is higher than needed.

C. Regular Wi-Fi cards installed in client devices do not support the same protocols as survey adapters.

D. USB Wi-Fi adapters have a greater sensitivity than internal Wi-Fi adapters.

Your customer requires fast secure roaming. Which two types of roaming are specified in 802.11-2016 FT roaming that will help meet this goal?

A. Over-the-Air and Over-the-DS

B. Over-the-Air and Over-the-Wire

C. FT and OKC

D. FT and TKIP

What limitation exists when WMM is not enabled on an 802.11n WLAN?

A. 802.11 QoS will not be available

B. The maximum channel-width will be 20MHz

C. EDCA values will change

D. Only two ACs will be available

When installing APs on high ceilings, what should be the most common PPE to be used?

A. Hardhat, high visibility vest and body belt

B. Glasses, gloves and jacket

C. Clean suits, masks and glasses

D. Clean suits, gloves and jacket

Which DHCP option, when required, should be configured and enabled to help APs locate their wireless LAN controller?

A. 150

B. 62

C. 43

D. 22

In what circumstance would you not enable DFS channels on a WLAN infrastructure?

A. In any stadium

B. In any office complex

C. In an airport

D. In any home office

When doing some frame capturing over the air during a voice call, you realized that frames on the downlink (from the AP to the client) direction are not being transmitted with the correct UP value for voice frames, but on the uplink (from the client to the AP) direction are being transmitted correctly. What's the cause of this issue?

A. Bad client driver

B. AP is not receiving enough PoE, thus not using QoS features

C. Somewhere on the wired network QoS markings aren't being trusted

D. Faulty antenna on the AP
