Free Certified Wireless Design Professional – Wi-Fi Design CWDP-303 Exam Practice Test

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?

• EAP-FAST
• EAP-TTLS
• EAP-TLS
• PEAP

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?

• Redesign the entire WLAN
• Quickly add more APs
• Upgrade the Ethernet connections to MultiGig
• Turn up the output power on the APs so that they can handle more clients

When designing a static channel plan for an office using voice devices near an airport, which range of channels should be avoided to ensure optimal performance when implemented?

• 36-40
• 44-48
• 116-124
• 1-11

Which type of authentication and encryption method is mandatory for Voice Enterprise certified devices as specified by the Wi-Fi Alliance?

• WPA2/AES Personal
• WPA2/TKIP Enterprise
• WPA2/AES Enterprise
• WPA/TKIP Personal

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?

• -70 dBm
• -67 dBm
• -65 dBm
• -63 dBm

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?

• It does not give you enough bandwidth to collect data coming from all of the adapters.
• It does not give you enough power for all four of your adapters.
• It generates noise in the 2.4 GHz band, giving you a false perception of the noise floor.
• It generates noise in the 5 GHz band, giving you a false perception of the noise floor.

A company wants to connect its headquarters to its remote office that is 13 kilometers away using a wireless bridge. What requirement must not be forgotten by their Wireless Engineer when considering the Fresnel Zone?

• Earth bulge
• Antenna gain
• FSPL
• Receive sensitivity

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

• Frequency Selection
• Roaming
• AP vendor
• Band steering

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

• CEO or CFO
• End-users
• The customer's customers
• Remote workers

In high-density environments, such as stadiums and convention centers, what extra factor has to be taken into account that can attenuate Wi-Fi signals when these environments are having an event?

• Thick walls
• I-Beams
• People
• Fire doors
