CWNP CWDP Wi-Fi Design CWDP-303 Questions & Answers

• Question 1:

  In a convention center, you have received complaints about the WLAN infrastructure. At this moment, the are only two APs in one auditorium. After analyzing the situation, you determined that there are more client devices that the infrastructure was designed for. There are only two APs to support more than 300 devices using the Wi-Fi at the same time. What should you do to make the Wi-Fi work as expected?

  A. Redesign the entire WLAN

  B. Quickly add more APs

  C. Upgrade the Ethernet connections to MultiGig

  D. Turn up the output power on the APs so that they can handle more clients

  Correct Answer: A

• Question 2:

  While performing a validation site survey, you realize that overlapping channels are being used on the 2.4 GHz bad due to the automatic channel assignment algorithm of the WLAN infrastructure. What should you do to prevent this?

  A. Reconfigure the automatic channel assignment settings to use only channels 1, 6, and 11

  B. Purchase and deploy new APs from a different vendor

  C. Reconfigure the network to use static channel plans because automatic channel assignment algorithms are all broken

  D. Leave it as it is; sometimes using all 11 channels in 2.4 GHz gives the optimum performance result

  Correct Answer: A

• Question 3:

  During a validation site survey, you realize that the installers mounted some of the APs above the ceiling. They said that this was a request from the building architect due to aesthetics constraints. During the requirements gathering, you weren't advised about any aesthetics constraints from the main stakeholder of the project. What should you do in this case?

  A. Advise the stakeholder that WLAN performance requirements will not be met and a new design process will be needed to meet the requirements.

  B. Leave it as it is and allow automatic channel management to correct any issues.

  C. Increase the output power on all APs by 6 dB immediately.

  D. Remove all external antennas and use only the internal antennas to reduce multipath.

  Correct Answer: A

• Question 4:

  Who should be in the final meeting from the customer-side after successfully implementing a WLAN infrastructure?

  A. CEO or CFO

  B. End-users

  C. The customer's customers

  D. Remote workers

  Correct Answer: B

• Question 5:

  What are the deliverables to your customer after successfully implementing a WLAN infrastructure?

  A. Digital or physical assets, guides, floorplans and configuration documents

  B. Project Charter

  C. Facility blueprints

  D. Nothing is required. The implemented WLAN was deliverable

  Correct Answer: A

• Question 6:

  You have performed a validation site survey after deploying a WLAN infrastructure that is an All-Wireless-Office. One specific application of your customer is experiencing delay when using the application after moving from wired connectivity. After your validation, you realized that all APs are using 80 MHz channel-widths instead of 20 MHz on the 5 GHz band, as it was designed. What can be done to resolve the delay on this application?

  A. APs should be using 160 MHz channel-widths to get more throughput

  B. Reconfigure to use 20 MHz channel-widths, so reuse of the frequency is more effective

  C. Power-off half of the APs to reduce CCI and keep 80 MHz channel-widths

  D. Add more APs using 80 MHz channel-widths

  Correct Answer: B

• Question 7:

  After designing and deploying a WLAN infrastructure, you realized the CCI is causing poor performance in the 2.4 GHz band. Primarily, you've designed the WLAN for 5 GHz and 2.4 GHz as a best effort. You found out that the implementers didn't follow your guidelines when configuring the WLAN infrastructure.

  What can you do to minimize as much as possible the CCI impact in the 2.4 GHz band?

  A. Add more APs to the infrastructure

  B. Increase the transmit power on all APs

  C. Turn-off 2.4 GHz radios on some APs

  D. Use all channels available in the 2.4 GHz band

  Correct Answer: C

• Question 8:

  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. His tablet doesn't support the 5 GHz band

  B. His tablet only supports a 40 MHz channel-width

  C. His tablet does not support one or more of the 5 GHz channels

  D. His tablet doesn't support MU-MIMO

  Correct Answer: D

• Question 9:

  During lunch time in the break room of a company, Wi-Fi connectivity on the 2.4 GHz band is intermittent. Every other time of the day, it works fine. What's the likely cause of this issue?

  A. Employees are using their cell data instead of using the Wi-Fi

  B. The AP in the cafeteria keeps rebooting due to lack of PoE budget on the switch

  C. Toasters and ovens are heating up the air, raising the noise floor with the Wi-Fi on the 2.4 Ghz band

  D. Microwaves in the cafeteria are interfering with the Wi-Fi on the 2.4 GHz band

  Correct Answer: D

• Question 10:

  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?

  A. Verify that the shared secret between the authenticator and the RADIUS server is correct

  B. Reboot the clients

  C. Reboot the server

  D. Restart the RADIUS service

  Correct Answer: A
