CWNP Certified Wireless Design Professional CWDP-304 Prüfungsfragen mit Lösungen
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.
Antwort: B 🗳️
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
Antwort: D 🗳️
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.
Antwort: A 🗳️
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.
Antwort: A 🗳️
How are EAP messages transported over 802.11 wireless LANS?
Response:
- A. EAPOL
- B. EAP_TLS
- C. EAP-Fast
- D. PEAP
