質問 1：
When performing an indoor predictive site survey to make the WLAN planning and design cycle more efficient, what is a best practice for configuration of the simulated APs in the predictive modeling software?
A. If dynamic RRM will be used, AP transmit power should be set to an estimated average level of the expected client devices, such as 25 mW.
B. All simulated APs should be set to 20 MHz channels only.
C. Always use the default 2.2 dBi omnidirectional antenna patterns for simulated APs.
D. Defining custom AP and antenna patterns will yield more accurate prediction data than the pre-configured vendor AP/antenna combinations.
正解：A

質問 2：
When preparing a floor plan graphic for use in predictive and manual site surveying, what calibration method will lead to the most accurate and reliable RF data?
A. Use the known size of a small object, such as a ceiling tile, and use a single instance of this object (e.g. a single ceiling tile) to scale the floor plan.
B. Use the longest available measurement (like a straight exterior wall) to calibrate the graphic's scale.
C. Measure the width of an actual office doorway with a tape measure and use this value to calibrate against a doorway graphic.
D. Calibrate the ceiling height of the floor plan first, then the survey software should be able to auto-calibrate the X and Y planes of the graphic.
正解：B

質問 3：
You are being asked to design a WLAN for a number of WLAN clients that will use Telnet as the primary application. The customer has asked that you use only the number of APs necessary because of the complex installation and construction costs each AP installation will incur in this particular environment.
What design factors do you consider?
Response:
A. Clients could benefit from RTS/CTS mode for all transmissions.
B. Omnidirectional antennas should be used to maximize cell overlap.
C. Use 11 Mbps as the lowest basic rate.
D. AP transmit power should be turned down to minimize co-channel interference.
正解：A

質問 4：
In an RSN requiring low-latency reassociations and no fast secure roaming protocols, what security solutions are ideal for protecting VoWiFi communication?(Choose all that apply.) Response:
A. WPA-Personal
B. WPA2-Enterprise
C. WPA2-Personal
D. 802.1X/EAP
E. WEP
正解：B,C

質問 5：
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 switchport that the AP is connected to is only capable of transmitting at 10 Mbps.
B. The AP in the room is transmitting on channel 13 and the traveler associated to a non-channel 13 AP located elsewhere.
C. The AP in the room is using Bluetooth instead of Wi-Fi.
D. The AP in the room is using ZigBee instead of Wi-Fi.
正解：B

CWNP Certified Wireless Design Professional 認定 CWDP-304 試験問題:

1. A wireless engineer from your company performed a site survey in an office building where a wireless network extension was needed. He reports that while performing a Layer 1 sweep near a meeting room full of people, he detected RF activity with a very low duty cycle. He is unsure how to interpret what he recorded to determine its impact on a future Wi-Fi network.
What is true about this RF environment and its potential impact on the WLAN?

A) The signal has a low duty cycle and should not be of major impact on the wireless network.
B) The signal is typical of a high radio card background noise. It shows that the card used for the Layer 1 sweep should be replaced and the Layer 1 sweep re-
C) The signal affects the entire spectrum and will render the wireless network unusable. It must be located and removed.
D) The signal is alternating between peaks (high interference level) and valleys (low interference level).
The network channel design must be
built to avoid the affected peak frequencies.

2. What differences exist between VLANs in wireless and wired domains?
Response:

A) Wireless VLANs are not effective for segmenting the available services and network permissions available to clients. Wired VLANs are effective for this purpose.
B) Wireless VLANs do not always segment traffic into separate broadcast domains on the wireless medium. Wired VLANs do segment broadcast domains on the wired network.
C) Wireless VLANs are not an effective way to utilize a single set of infrastructure equipment to provide different services to different client groups. Wired VLANs are effective for this purpose.
D) Wireless VLANs are never carried in 802.11 frames that cross the wireless medium. VLAN identifiers are always carried in Ethernet frames to indicate the proper VLAN.

3. Given:
In your regulatory domain, a Tx Power Level of "1" is equivalent to 17 dBm.
For every integer increment (e.g. from 1 to 2) to the Tx Power Level, the APs transmit power is halved.
In units of mW, what is the actual transmit power for an AP configured at a Tx Power Level of "4"?

A) 12.5 mW
B) 8 mW
C) 6.25 mW
D) 50 mW

4. What is a valid 40 MHz channel configuration in the 2.4 GHz ISM band where channels 1-11 are permitted?

A) 4 (primary), +1 (secondary)
B) 8 (primary), +1 (secondary)
C) 2 (primary), -1 (secondary)
D) 1 (primary), 6 (secondary)

5. A high power radio system transmits at 40,000 Watts. What is this power in dBm? Solve this without a calculator.
Response:

A) 46 dBm
B) 66 dBm
C) 76 dBm
D) 56 dBm
