Q96. You are troubleshooting an issue reported by several wireless users. The problem is contained to one cell (several users connected to the same AP). You manage the WLAN and no other network devices. After analysis it appears to be a switch problem. What action should be taken?

Q97. During a post-implementation survey, you have detected a non-802.11 wireless device transmitting in the area used by handheld 802.11g scanners. What is the most important factor in determining the impact of this non-802.11 device?

Q98. You are implementing a multi-AP WLAN and fast secure roaming is essential.
Which one of the following methods is an IEEE 802.11 standard method for fast roaming?

Q99. When an ACK frame is not received by the transmitting STA, what is assumed?

Q100. You are deploying a WLAN with the access points configured for 10 mW of output power on the 2.4 GHz radios and 20 mW of output power on the 5GHz radios. Some semi-directional antennas are also in use. What kind of deployment is described?

Q101. An RF signal sometimes bends as it passes through some material other than free space. What is the term that describes this behavior?

Q102. A WLAN transmitter that emits a 50 mW signal is connected to a cable with 3 dB loss. If the cable is connected to an antenna with 9dBi gain, what is the EIRP at the antenna element?

Q103. In which plane of the three networking planes is an access point configured by a WLAN controlled?

Q104. You administer a WLAN that offers a guest SSID of GUESTNWORK. User connect to the GUESTNWORK SSID, but report that they cannot browse the internet. The devices simply report no internet connection. What common problem causes this scenario?

Q105. What feature was introduced in the 802.11h amendment in order to uphold regulatory requirements for 5 GHz operations.

Q106. Your consulting firm has recently been hired to complete a site survey for a company. Your engineers use predictive design software for the task, but the company insists on a pre- deployment site visit. What task should be performed as part of the pre-deployment visit to prepare for a predictive design?

Q107. What security solution is deprecated in the 802.11 standard and should never be used in any modern WLAN deployment?

Q108. What factors does not influence the distance at which an RF signal can be effectively received?

Q109. An 802.11 WLAN transmitter that emits a 50 mW signal is connected to a cable with 3 dB of loss.
The cable is connected to an antenna with 16 dBi of gain.
What is the EIRP power output?

Q110. You support a WLAN using dual- band 802.11ac three stream access points. All access points have both the 2.4 GHz and 5 GHz radios enabled and use 40 MHz channels in 2.4 GHz. A manager is concerned about the fact that each access point is connected using a 1 Gbps Ethernet link. He is concerned that the Ethernet link will not be able to handle the load from the wireless radios. What do you tell him?

Q111. Prior to association, what parameter can 802.11 client devices measure and use to select the optimal access point for association?
