出題：1

You are troubleshooting a problem with interference from a non-802.11 device. Given that the device is not a WLAN device, you cannot use a protocol analyzer and have chosen to use a spectrum analyzer. You want to view the signal from the interfering device over time to see the activity that is generating.
What common spectrum analyzer view should you use for this analysis?

A. Waterfall/Spectrogram

B. Real-time FFT

C. Clients

D. APs

What statement about 802.11 WLAN performance is true?

A. In most WLANs, no special skill or tuning is required to get peak performance

B. WLANs perform better as more wireless clients connect with each AP

C. To get the best performance out of an AP, you should disable data rates of 72 Mbps and lower

D. In modem networks, both centralized and distributed data forwarding work well for most standard office deployments

出題：4

What facts are true regarding controllers and APs in a Split MAC architecture?

A. Management and data frame types must be processed locally by the AP, while control frame types must be sent to the controller.

B. Using centralized data forwarding, APs never tag Ethernet frames with VLAN identifiers or 802.1p CoS.

C. An IP tunnel is established between the AP and controller for AP management and control functions.

D. With 802.1X/EAP security, the AP acts as the supplicant and the controller acts as the authenticator.

出題：8

You manage a WLAN with 100 802.11ac access points. All access points are configured to use 80 MHz channels. In a particular BSS, only 40 MHz communications are seen. What is the likely cause of this behavior?

A. The short guard interval is also enabled

B. The clients are all 802.11n STAs or lower

C. All clients implement single spatial stream radios

D. The AP is improperly configured to use only 40 MHz of the 80 MHz allocated bandwidth
