CWDP-303 Sample Questions Answers

What is the most suitable antenna option to be used when designing a WLAN infrastructure with APs mounted on a ceiling with a height of more than 20 feet and having all of the client stations used from the floor?

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?

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?

You are conducting a physical site survey where heavy machinery is repaired. What is a common item required specifically for this type of survey?

You’re about to deploy an Enterprise-class VoWLAN infrastructure. You need to ensure that QoS is properly configured throughout the network. What Access Category (AC) should voice frames/packets use?

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

You’re preparing to perform a site survey for a company that processes meat. Some areas are restricted due to high-security. What do you have to do in order to proceed with the site survey?

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?

When deploying a new WLAN infrastructure using PoE to power the APs, you realize that a known good AP is not powering up. You use the same cable to connect your laptop and connect without any trouble. What is the most likely reason the AP did not power up?

Which document provided to your customer should include all devices and parts that are going to be used during the deployment of their WLAN infrastructure?

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 museum wants to offer Wi-Fi to its visitors. One of their requirements is to have the APs blend into the design of the museum. What should you do to meet this requirement?

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?

After importing a floor plan to a predictive design tool, what should be done prior to adding APs, antennas and attenuators (e.g., walls)?

When surveying an existing WLAN infrastructure for a possible redesign, you use two Wi-Fi USB adapters to collect RSSI data and two USB spectrum analysis adapters to collect RF spectrum data. Since your laptop doesn’t have enough USB ports, you use a 4-port powered USB 3.0 hub. What issues could be caused by the use of USB 3.0 that will impact your site survey?
