CWAP-404 無料問題集「CWNP Certified Wireless Analysis Professional」

（A）Radio and antenna hardware used for protocol analysis may not match the receive sensitivity, diversity, MIMO, or antenna gain capabilities of the network WLAN hardware.

（B）If protocol analysis software is not properly configured with frame decryption parameters, it can't accurately calculate a CRC, which includes the encrypted frame body contents.

（C）Layer 2 protocol analysis can only collect and interpret data that is received properly at the MAC layer, and cannot quantify some PHY-layer problems.

（D）If the protocol analysis radio hardware is not located in the same area as intended client devices or APs, its data sampling may not be representative of actual traffic on the network.

（A）A new microwave oven was installed in the cafeteria.

（B）A Terminal Doppler Weather Radar (TDWR) is causing a DFS response across the entire band.

（C）A wideband RF power source is corrupting all IEEE 802.11 transmissions.

（D）A malfunctioning IEEE 802.11 OFDM radio card is transmitting continuously.

（E）A manual site survey tool is actively testing the throughput of their WLAN.

（A）Multiple of them can be applied simultaneously

（B）Once created they are reusable for later captures

（A）There are at least three APs operating in this environment.
They are operating on channels 149, 153, and 161.

（B）Only one AP in this network is configured to use the upper UNII band (UNII-3).
All other APs are in lower 5 GHz channels.

（C）There are two 40 MHz BSSs in this environment.
One AP has some 40 MHz traffic while the other AP has no client traffic.

（D）Two 802.11a APs are near the spectrum analyzer and are heavily utilized on channels 149 and
153.

（A）Capture from another AP in another BSS

（B）Directly in the middle of the AP and client STA

（C）Very near the client STA

（D）Very near the AP
