CWNP Certified Wireless Design Professional CWDP-304 Prüfungsfragen mit Lösungen:
1. An associated STA detects a new BSS with the same SSID as the STA's current BSS. The new BSS uses a different IP subnet than the current BSS.
If the STA is configured to use 802.1X/EAP preauthentication, what is likely to occur?
A) The STA will attempt to preauthenticate and succeed if DHCP is supported on the new subnet.
B) The STA will attempt to preauthenticate, but fail because the new BSS uses a different data-link broadcast domain.
C) The STA will attempt to preauthenticate and succeed if IP Mobility is enabled on the AP or WLAN controller.
D) The STA will not attempt to preauthenticate because the new BSS uses a different IP subnet.
2. A WLAN that you designed has been deployed in one area, users ate complaining that the network performs poorly. When you analyze the area you see that a new interferer has been introduced that was not there during the pre-design survey You've been informed that the interferer cannot be removed as it is an essential loT device. What action do you recommend?
A) Place a metal enclosure around the interferer
B) Use 40 MHz channels so that the devices can use either 20 MHz block depending on where the interferer operates
C) increase the output power of the APs covering that area by at least 25 percent to overpower the interferer
D) Reconfigure the channel plan to work around the interferer
3. What are some common problems with short (12 or fewer characters) ASCII passphrases in WPA/WPA2- Personal networks?
Response:
A) They are more susceptible to dictionary attacks than longer passphrases.
B) They only produce a 64-bit PMK instead of a 256-bit PMK.
C) Very few AP and client vendors support entry of an ASCII-based passphrase.
D) They lead to weak group keys in a BSS.
4. You are on site, planning a network at a freight shipping company on a busy harbor. Since the preliminary WLAN design specifies support for the 5 GHz spectrum, you would like to test for radar pulses to determine if DFS channels should be supported at this facility. As a part of your spectral survey with a laptop-based analyzer, you include DFS testing to identify the presence of radar. This is done by manually observing Real-time FFT, Duty Cycle, and Active Devices charts of the spectrum analyzer software.
What potential drawback is present with this DFS test method?
A) Manual identification of radar pulses using spectrum analysis charts can be very difficult due to radar's low amplitude at the Wi-Fi receiver.
B) Many WLAN products that support DFS channels report several false positives. Ideally, the actual WLAN equipment used in the deployment should be used to test for DFS.
C) Modern spectrum analyzer adapters do not provide the necessary bandwidth resolution required to detect and measure radar signatures.
D) Some sources of 5 GHz radar, such as military ships, are mobile in nature. A longer, automated test setup should be used to identify the presence or absence of radar.
5. How are EAP messages transported over 802.11 wireless LANS?
Response:
A) EAPOL
B) EAP_TLS
C) EAP-Fast
D) PEAP
