CWNP CWNP Certifications CWDP-304 Questions & Answers

• Question 81:

  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 not attempt to preauthenticate because the new BSS uses a different IP 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 DHCP is supported on the new subnet.

  D. The STA will attempt to preauthenticate and succeed if IP Mobility is enabled on the AP or WLAN controller.

  Correct Answer: B

• Question 82:

  What is the minimum PoE budget needed on a switch to support 6 (six) APs that can only be powered using IEEE 802.3at if no other details are provided? Response:

  A. 320 W

  B. 60 W

  C. 180 W

  D. 240 W

  Correct Answer: C

• Question 83:

  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?

  A. Thick walls

  B. I-Beams

  C. People

  D. Fire doors

  Correct Answer: C

• Question 84:

  As you plan a WLAN upgrade, you have assessed the network requirements and data signatures of your applications. One of the popular applications used on your network requires high bandwidth and low to medium Wi-Fi loss, but can tolerate moderate latency and jitter.

  What application matches this description?

  A. Voice

  B. Email

  C. Skype chat

  D. Video-on-demand

  Correct Answer: B

• Question 85:

  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?

  A. Bad client driver

  B. AP is not receiving enough PoE, thus not using QoS features

  C. Somewhere on the wired network QoS markings aren't being trusted

  D. Faulty antenna on the AP

  Correct Answer: C

• Question 86:

  What kind of applications has the character traits of many communications back and forth between the server and client for each transaction initiated by the user? For example, several files, images and other data files may be required to download to the client with each click from the user. Choose the best answer. Response:

  A. mobile apps

  B. console management interfaces

  C. high-data bandwidth application

  D. real-time application

  E. web-based application

  Correct Answer: D

• Question 87:

  Using a SCA means that all APs will be using the same channel in a given layer. How is the AP with which the client associates determined? Response:

  A. All APs share a virtual Multicast Address. A controller will tell the closest AP to the client to communicate with it, since it has a greater RSSI from the client.

  B. All APs share a virtual BSSID. A controller will tell the closest AP to the client to communicate with it, since it has a greater RSSI from the client.

  C. All APs share a virtual IP address. A controller will tell the closest AP to the client to communicate with it, since it has a greater RSSI from the client.

  D. The client selects the AP based on a known set of MAC to BSSID mappings stored in the clients authorized SSID listing.

  Correct Answer: D

• Question 88:

  A business traveler from North America is in Europe. The hotel only provides coverage in 2.4 GHz. The traveler connects to the hotel's SSID and notices an AP in the hotel room.

  However, the laptop reports a very low RSSI when connected. The traveler does not have the same problem when connecting in the lobby.

  What would be the most likely cause of the low RSSI in the hotel room?

  Response:

  A. The AP in the room is transmitting on channel 13 and the traveler associated to a non- channel 13 AP located elsewhere.

  B. The AP in the room is using Bluetooth instead of Wi-Fi.

  C. The AP in the room is using ZigBee instead of Wi-Fi.

  D. The switchport that the AP is connected to is only capable of transmitting at 10 Mbps.

  Correct Answer: A

• Question 89:

  What strategy can be used to ensure efficient cell overlap for VoIP site surveys? Response:

  A. Measure the percentage of cell overlap using the cell overlap feature in the site survey software.

  B. Increase the output power of the radio in all APs.

  C. Install higher gain antennas in the APs.

  D. Ensure at least two APs can be seen with appropriate signal strengths from each location.

  Correct Answer: A

• Question 90:

  What document is typically created to launch a project?

  A. Bill of Materials

  B. Project Charter

  C. Work Breakdown Structure

  D. Budget

  Correct Answer: B
