Given: As the wireless network administrator for XYZ Company, you are planning to upgrade your aging wireless network infrastructure, as well as some clients, to support 802.11ac.
In your research, you have discovered that your new wireless client devices and infrastructure are 802.11ac, WMM, and WMM-PS certified by the Wi-Fi Alliance. Some of your existing client devices are 802.11a/b/g devices that do not support WMM.
Given this information, what scenario is possible when your company's employees begin using both types of client devices on the new WLAN?
Response:

A. The WLAN infrastructure will set the dozing times of the WMM-PS certified client devices based upon their WMM access category, while the non-WMM-PS client devices will continue to use PSPoll frames.

B. All WMM-PS certified client devices will be prevented from utilizing WMM-PS features until all stations in use on the wireless medium are WMM-PS certified.

C. WMM-PS enabled APs will allow both WMM-PS and non-WMM-PS stations to use the triggerand- delivery mechanism, but WMM-PS stations will g

D. Performance and battery life will be inconsistent between WMM-PS and non-WMM-PS client devices when used with applications that support WMM-PS.

After surveying the environment, you discovered that the noise floor is -88 dBm. What should be the minimum RSSI value to meet the system's requirements?

A. -70 dBm

B. -67 dBm

C. -65 dBm

D. -63 dBm

出題：3

An engineering firm just upgraded their WLAN form nine 802.11n APS to nine 802.11ac APs. After this upgrade, they did not see any improvement in throughput.
What is the most likely cause of this result?

A. The clients were not upgraded

B. APs are mounted on the wall

C. The APs are still using the 5 GHz lower band

D. APs are transmitting at a low transmit power

出題：4

What limitation exists when WMM is not enabled on an 802.11n WLAN?
Response:

A. 802.11 QoS will not be available

B. The maximum channel-width will be 20MHz

C. EDCA values will change

D. Only two ACs will be available

出題：5

While performing a validation site survey, you realize that overlapping channels are being used on the 2.4 GHz bad due to the automatic channel assignment algorithm of the WLAN infrastructure.
What should you do to prevent this?

A. Purchase and deploy new APs from a different vendor

B. Reconfigure the network to use static channel plans because automatic channel assignment algorithms are all broken

C. Leave it as it is; sometimes using all 11 channels in 2.4 GHz gives the optimum performance result

D. Reconfigure the automatic channel assignment settings to use only channels 1, 6, and 11

出題：7

After designing a WLAN infrastructure using predictive design software. What's the best way to validate the predictive design in the physical space before deployment, if time and budget allow for it?

A. Deploy all of the APs as they're shown in the predictive design and perform a passive site survey.

B. Perform an AP-on-a-Stick survey using AP locations based upon the predictive design to confirm each AP's placement.

C. Deploy all of the APs as they're shown in the predictive design and perform an active site survey.

D. Use a client device positioned where the APs will be installed and measure the signal from the client device.
