CWNP CWDP-302 問題集

質問 1：
You have determined the best mounting locations for APs in a given installation. The facilities manager has asked you to change the locations for several APs due to aesthetic concerns. You suggest mounting the APs in the ideal locations and painting them so they go unnoticed in the environment.
What is a valid recommendation or consideration when painting APs?
A. Painting APs may void the product manufacturer's warranty.
B. Painting APs will significantly reduce the output power.
C. Always use paints with metallic dye in them to prevent potential RF propagation impact.
D. Most AP models for indoor environments come in a variety of form factors and colors. Painting is never recommended.
正解：A

質問 2：
In a large enterprise (5000+ wireless users), by what would NOT be a recommended method by which IP addresses and VLANs are assigned to different clients associated to the same AP?
A. Multiple VLAN pools are designated for an SSID and user IP addresses are selected in a round-robin fashion from the associated pools
B. Upstream AAA servers dynamically assign VLANs to each user or group profile
C. Radio signal metrics (RSSI, SNR, etc.) of WLAN clients are triangulated for location-based VLAN assignment during association
D. Each SSID is mapped to a static VLAN assignment
正解：C

質問 3：
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. Email
B. Voice
C. Video-on-demand
D. Skype chat
正解：C

質問 4：
When a virtual controller architecture is in use, with most vendor solutions, how is the virtual controller assigned?
A. By the administrator directly
B. By the administrator through DNS configuration
C. By election among the APs
D. By election among the physical controllers
正解：A

質問 5：
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 6：
All of the APs in the WLAN you have designed are using the same RF channel. You plan to add a VoIP network in the future that will include several more APs that all use the same RF channel, but different from the existing WLAN design.
What model is certainly in use?
A. Autonomous
B. Cloud-based
C. SCA
D. MCA
正解：C

質問 7：
You must determine the SNR of a particular signal. You know the RSSI.
What additional metric is required?
A. CCI ratio
B. Throughput rate
C. Data rate
D. Noise floor
正解：D

質問 8：
When using a throughput tester, what protocol should be tested if you are concerned about VoIP call streams?
A. PPTP
B. TCP
C. UDP
D. RDP
正解：C
