質問 2：
You have installed a new 802.1 lac WLAN configured with 80 MHz channels. Users in one area are complaining about poor performance. This area is currently served by a single AP. You take a spectrum analysis capture in the poor performing area. While examining the waterfall plot you notice the airtime utilization is higher on the first 20 MHz of the 80 MHz channel when compared to the rest of the channel.
What do you conclude?
A. RRM is enabled and has dynamically picked a 20 MHz channel
B. The AP is misconfigured and needs to be reconfigured to 80 MHz operation
C. Non-Wi-Fi interference is preventing the APs 80 MHz operation
D. The first 20 MHz is the AP's primary channel and higher airtime utilization on the primary channel is normal when an AP is configured for 80 MHz operation

質問 4：
A manufacturing facility has installed a new automation system which incorporates an 802.11 wireless network. The automation system is controlled from tablet computers connected via the WLAN. However, the automation system has not gone live due to problem with the tablets connecting to the WLAN. The WLAN vendor has been onsite to perform a survey and confirmed good primary and secondary coverage across the facility. As a CWAP you are called in to perform Spectrum Analysis to identify any interference sources.
From the spectrum analysis, you did not identify any interference sources but were able to correctly identify the issue. Which of the following issues did you identify from the spectrum analysis?
A. The tablets are entering power save mode and failing to wake up to receive the access points transmissions
B. The tablets are connecting to the wrong SSID
C. A high noise floor has resulted in a SNR of less than 20dB
D. There is a power mismatch between the APs and the clients
正解：D

質問 5：
What is the difference between a Data frame and a QoS-Data frame?
A. QoS Data frames include an 802.1Q VLAN tag
B. QoS Data frames include a DSCP control field
C. QoS Data frames include a QoS control field
D. QoS Data frames include a QoS information element

質問 6：
Which one of the following is required for Wi-Fi integration in laptop-based Spectrum Analyzer software in addition to the spectrum analysis adapter?
A. A firmware upgrade for the spectrum analysis adapter
B. SNMP read credentials to the WLAN controller or APs
C. An 802.11 wireless adaptor
D. A directional antenna
