문제6

The BSA of an AP covers the area used by the sales and marketing department. Thirty-five stations operate in this space. The users indicate that they need more throughput and all stations are 5 GHz capable 802.11ac clients. The current AP configuration uses 20 MHz channels in both 2.4 GHz and 5 GHz. What is the least expensive solution available for increasing throughput for these users without implementing configuration options that are not recommended?

A. Install a second AP in the coverage area

B. Use a 160 MHz channel on the 5 GHz radio

C. Use a 40 MHz channel on the 5 GHz radio

D. Use a 40 MHz channel on the 2.4 GHz radio

문제7

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.

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. Clients

C. Real-time FFT

D. APs
