Your organization would like to give their network field engineers a tool to provide an overview of a given wireless LAN environment. They are interested in how many SSIDs are enabled per radio, channels used, and the number of APs per channel. They do not want to require the engineers to view multiple frames to determine the information. Which tool would you recommend that provides this information at the lowest cost?

A. Site Survey Software

B. Protocol Analyzer

C. WLAN Scanner

D. Spectrum Analyzer

B. DA = MAC of default gateway; RA = BSSID of the AP to which the STA is associated

C. DA = BSSID of the targeted AP; RA = Ethernet MAC of the targeted AP

D. DA = MAC of the default gateway; RA = Ethernet MAC of the targeted AP

You have been engaged by ABC corporation to troubleshoot a WLAN problem. Users have been reporting random disconnections. You perform Spectrum Analysis as part of your troubleshooting process and notice a frequency hopping signal across the entire 2.4 GHz band. The signal amplitude is -65 dBm and has a duty cycle of 5%. What do you conclude about this frequency hopping signal?

A. The low duty cycle means this signal is very unlikely to be the cause of the disconnections.

B. Only clients with a lower signal strength will be disconnected.

C. Interference from frequency hopping signals always results in client disconnections.

D. The high amplitude of this signal is overpowering the Wi-Fi clients resulting in the disconnections.

Which statement accurately describes IEEE 802.11 Power Save operation in a Basic Service Set that does not support the QoS facility?

A. After waking from a low power state, client stations listen for the next Beacon to determine if sending a PS-Poll frame to the access point is necessary.

B. When the access point's buffer is full, the access point wakes all client stations using a PS-Poll frame so that they can receive the data.

C. Following a period of time in a low power state, client stations wake themselves and automatically poll the access point for traffic using a PS-Poll frame.

D. After waking at a scheduled TBTT, client stations send Null Function frames to the access point with the Power Management bit set back to zero.

E. Upon receiving traffic for a dozing station, the access point wakes the client station using a PS- Poll frame so that the client station can receive the data.
