質問 4：
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?
Response:
A. Reconfigure the network to use static channel plans because automatic channel assignment algorithms are all broken
B. Leave it as it is; sometimes using all 11 channels in 2.4 GHz gives the optimum performance result
C. Reconfigure the automatic channel assignment settings to use only channels 1, 6, and 11
D. Purchase and deploy new APs from a different vendor
正解：C

質問 5：
Given: For this fill-in the blank question, each answer option contains an answer for the first and second blanks, separated by a dash "-". Choose the answer option that correctly fills in both blanks in the following sentence.
A WLAN may use 802.11 admission control to ________, and admission control requirements are configured separately for each ________.
A. Identify voice-enabled wireless devices - AP radio (that is, 2.4 GHz or 5 GHz)
B. Mark ingress and egress frames with priority values - TCP/IP port
C. Block stations with inadequate security parameters - SSID
D. Regulate the available bandwidth resources - Access Category
正解：D

質問 6：
In a convention center, you have received complaints about the WLAN infrastructure. At this moment, the are only two APs in one auditorium. After analyzing the situation, you determined that there are more client devices that the infrastructure was designed for. There are only two APs to support more than 300 devices using the Wi-Fi at the same time. What should you do to make the Wi-Fi work as expected?
A. Turn up the output power on the APs so that they can handle more clients
B. Redesign the entire WLAN
C. Quickly add more APs
D. Upgrade the Ethernet connections to MultiGig
正解：B

質問 7：
A high power radio system transmits at 40,000 Watts. What is this power in dBm? Solve this without a calculator.
Response:
A. 46 dBm
B. 66 dBm
C. 76 dBm
D. 56 dBm
正解：C

質問 8：
Why should band steering algorithms allow stations to connect to the 2.4 GHz band after some number of ignored Probe Requests?
A. Because the 802.11 standard requires it.
B. Because the AP will experience a buffer overflow if they do not eventually respond with a Probe Response.
C. Because some clients are persistent clients that will not move on to the 5 GHz band.
D. Because the FCC requires it.
正解：C

質問 9：
When performing a roaming test and packet capture at the same time, what are two particular frames that will be present when roaming between two APs is successful?
A. Probe Request and Probe Response
B. Reassociation Request and Reassociation Response
C. Association Request and Association Response
D. Beacon and DTIM
正解：B
