CWNP Certified wireless analusis professional(cwap) 認定 PW0-205 試験問題：
問題 #1
Before accurate statistical troubleshooting with a wireless protocol analyzer can be performed on a wireless LAN, which of the following must be completed?
A. Operational traffic policy
B. Traffic injection analysis
C. Directional traffic filtering
D. Quality of Service (QoS) design
E. Baseline traffic analysis
問題 #2
As a wireless LAN consultant, you have been contacted by one of your customers to go to their premises to troubleshoot a problem with a single wireless client station (Station-Z).
Your customer informs you that other wireless client stations are not having problems with wireless connectivity, and that Station-Z is configured in the same manner as all other wireless client stations on the network. Station-Z is showing an unusually high retransmission count in its client utilities. Using a wireless protocol analyzer, where and how would you begin troubleshooting this problem?
A. Position the analyzer near Station-Z. Analyze the frames Station-Z is receiving, looking for corrupted frames.
B. Position the analyzer half way between Station-Z and the access point. Analyze the distance between Station-Z and the access point.
C. Position the analyzer near Station-Z. Analyze Station-Z transmissions and acknowledgements. Look for RF and obstacle-induced interference.
D. Position the analyzer near the access point. See if Station-Z frames are reaching the access point and if so, analyze their signal strength.
E. Position the analyzer half way between Station-Z and the access point. Analyze the data rate at which frames are sent and how long they take to be received.
問題 #3
Which of the following steps must be taken prior to use of a wireless LAN protocol analyzer?
A. Install a special driver for the specific wireless LAN card being used.
B. Load special firmware into the wireless LAN card being used for analysis.
C. Load the wireless LAN protocol interpreter engine provided by the manufacturer.
D. Disable all installed network adapters except for the wireless LAN card in use.
E. Configure the wireless LAN card client utilities for RF Monitor mode.
問題 #4
ABC Company is having throughput problems on their 802.11b wireless LAN. A wireless administrator has noticed in the wireless client station utilities that the MAC CRC Error count is higher on stations with problems than those client stations without problems. A high MAC CRC Error count is NOT attributable to which of the following?
A. Overlapping access point coverage on a single channel
B. Collisions due to dense population of client station adapters
C. High multipath conditions due to bounced signals
D. 2.4 GHz ISM band interference from sources such as wireless phones
E. Co-located PCF and DCF mode access points that are using non-overlapping 2.4 GHz channels
問題 #5
Using the wireless protocol analyzer trace shown, a wired station (00:C0:9F:07:66:26) is sending a Ping Request to an 802.11b wireless client station (00:0C:30:52:93:6A). What is the best explanation as to why the Ping Request is being sent from the access point to the wireless client station at 11 Mbps while the Ping Reply is being sent from the wireless client station to the access point at 5.5 Mbps?
A. Another client station is sending data to the same access point at a data rate of 5.5 Mbps, causing all client stations in its immediate area to transmit at the same rate.
B. The client station is moving further from the access point and has slowed its transmission rate to signal to the access point that it should do the same.
C. Transmission and reception rates are configured independently on each client station and announced to the access point in probe requests.
D. An RF interference source is located near the client station causing it to slow its transmission rate in order to successfully communicate with the access point.
