CWNP CWDP-305 問題集

質問 1：
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 2：
Which one of the following might be detected as a source of CCI during a post-validation survey in the 5 GHz band?
A. Other HR/DSSS networks
B. Other ERP networks
C. Other OFDM networks
D. Microwave ovens
正解：C

質問 3：
What is an advantage of centralized data forwarding?
A. It allows for centralized filtering of wireless traffic
B. It increases the signal strength for wireless client devices
C. It increases the encryption strength for user traffic
D. It reduces delay for user traffic
正解：A

質問 4：
You are site surveying a network for VoWiFi. You have positioned an AP for a manual survey and are moving away from the AP with a phone in Survey Mode in your hand and you are reading the RSSI value of the signal received from the AP. You have previously determined that the noise floor was approximately -94 dBm on this floor of the building. The phones documentation does not specify a recommended RSSI or SNR value for best performance.
Based on the information provided and the type of device (VoWiFi phone) you are deploying, what minimum RSSI should you plan for in all areas you are monitoring and where VoWiFi service is desired?
A. - 72 dBm
B. - 62 dBm
C. - 75 dBm
D. - 67 dBm
正解：D

質問 5：
During a public Wi-Fi session with 10 other users, you run a ping sweep but cannot detect any devices on your subnet. What feature is likely enabled on the WLAN infrastructure to prevent local communication between clients?
A. Band steering
B. Load balancing
C. Peer-to-peer blocking
D. OSPF external routes
正解：C

質問 6：
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
正解：A

質問 7：
Which document provided to your customer should include all devices and parts that are going to be used during the deployment of their WLAN infrastructure?
A. Design report
B. Project plan
C. SoW
D. BoM
正解：D

質問 8：
When installing a cloud-based AP, what is the most common process used?
Response:
A. Connect the AP to the network and configure it from the cloud assigning a configuration or policy set to the AP.
B. Configure the AP as an autonomous AP and then, when it connects to the cloud, it will be reconfigured.
C. Configure a profile for the AP in the cloud and then connect it for automatic configuration.
D. Configure the AP with a local controller and then, when it connects to the cloud, it will be reconfigured.
正解：C

質問 9：
You are conducting a physical site survey where heavy machinery is repaired. What is a common item required specifically for this type of survey?
A. Indoor APs
B. Low gain antennas
C. Personal Protective Equipment (PPE)
D. Low power APs
正解：C
