質問 2：
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. 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.
B. Performance and battery life will be inconsistent between WMM-PS and non-WMM-PS client devices when used with applications that support WMM-PS.
C. 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.
D. 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
正解：B
質問 3：
Switches and APs have already been chosen by your customer. All switches support 802.3bz MultiGig interfaces and APs are 4x4:4 802.11ac wave 2 capable of using dual-5GHz and have one MultiGig interface. Some cable drops for the APs will run for more than 180.5 feet (or 55 meters). To support MultiGig, what is the best choice of cabling?
A. Cat-5
B. Cat-5e
C. Cat-6a
D. Cat-6
正解：C
質問 4：
A high power radio system transmits at 40,000 Watts. What is this power in dBm? Solve this without a calculator.
Response:
A. 66 dBm
B. 76 dBm
C. 46 dBm
D. 56 dBm
正解：B
質問 5：
In what circumstance would you not enable DFS channels on a WLAN infrastructure?
A. In any stadium
B. In any home office
C. In any office complex
D. In an airport
正解：D
質問 6：
After designing and deploying a WLAN infrastructure, you realized the CCI is causing poor performance in the 2.4 GHz band. Primarily, you've designed the WLAN for 5 GHz and 2.4 GHz as a best effort. You found out that the implementers didn't follow your guidelines when configuring the WLAN infrastructure. What can you do to minimize as much as possible the CCI impact in the 2.4 GHz band?
A. Turn-off 2.4 GHz radios on some APs
B. Add more APs to the infrastructure
C. Use all channels available in the 2.4 GHz band
D. Increase the transmit power on all APs
