質問 1：
A wireless engineer from your company performed a site survey in an office building where a wireless network extension was needed. He reports that while performing a Layer 1 sweep near a meeting room full of people, he detected the RF environment displayed in the exhibit. He is unsure how to interpret what he recorded to determine its impact on a future Wi-Fi network.

What is true about this RF environment and its potential impact on the WLAN?
A. The signal has a low duty cycle and should not be of major impact on the wireless network.
B. The signal is alternating between peaks (high interference level) and valleys (low interference level). The network channel design must be built to avoid the affected peak frequencies.
C. The Real Time FFT shows a high amplitude, narrowband jammer pulsing across the entire 2.4 GHz band. This will cause significant, intermittent interference to the WLAN.
D. The signal is typical of a high radio card background noise. It shows that the card used for the Layer 1 sweep should be replaced and the Layer 1 sweep re-done.
E. The signal affects the entire spectrum and will render the wireless network unusable. It must be located and removed.
正解：A

質問 2：
Given: The 802.11n APs you have selected for your public access deployment support many of the PHY and MAC enhancements offered by the 802.11n standard. The AP is single-band (2.4 GHz) and only allows 20 MHz channels. The WLAN radio in the AP is a 3x3 802.11n chip that supports two spatial streams.
What is the maximum MCS rate that could be supported by this AP?
A. 54 Mbps
B. 150 Mbps
C. 300 Mbps
D. 65 Mbps
E. 144 Mbps
F. 108 Mbps
正解：E

質問 3：
ABC Manufacturing has a heavily-used dual-band (2.4 / 5 GHz) WLAN, but sporadic RF interference across the 2.4 GHz band is causing dropped VoWiFi calls and leading to data connectivity and throughput problems.


What steps should ABC Manufacturing take to most effectively remedy this problem?
A. Solution 4
B. Solution 1
C. Solution 3
D. Solution 2
正解：D

質問 4：
An associated STA detects a new BSS with the same SSID as the STA's current BSS. The new BSS uses a different IP subnet than the current BSS. If the STA is configured to use 802.1X/EAP preauthentication, what is likely to occur?
A. The STA will attempt to preauthenticate and succeed if IP Mobility is enabled on the AP or WLAN controller.
B. The STA will attempt to preauthenticate, but fail because the new BSS uses a different data-link broadcast domain.
C. The STA will attempt to preauthenticate and succeed if the current AP has shared its cached PMK.
D. The STA will not attempt to preauthenticate because the new BSS uses a different IP subnet.
E. The STA will attempt to preauthenticate and succeed if DHCP is supported on the new subnet.
正解：B

質問 5：
The exhibit illustrates the azimuth and elevation for what type of antenna?

A. 120 degree horizontal sector
B. 20 degree vertical yagi
C. Omni-directional
D. 60 degree horizontal patch
E. 10 degree vertical grid
正解：A

質問 6：
As you plan a WLAN upgrade, you have assessed the network requirements and data signatures of your applications. One of the popular applications used on your network requires high bandwidth and low to medium Wi-Fi loss, but can tolerate moderate latency and jitter.
What application matches this description?
A. Video-on-demand
B. Video conferencing
C. Voice
D. Skype chat
E. Email
F. FTP
正解：A
