Practice with CWNA-108 Dumps for CWNA Certification Certified Exam Questions & Answer [Q74-Q98]

Q74. When using an RF splitter to connect one transceiver to sector antennas loss is incurred. What is this loss called?

Q75. You administer a small WLAN with nine access point. As a small business, you do not rum a RADIUS server and use WPA2-Personal for security. Recently, you changed the passphrase for WPA2-personal in all Aps and clients. Several users are now reporting the inability to connect to the network at time and it is constrained to one area of the building. When using scanner, you see that the AP covering that area is online

Q76. The IEEE 802.11-2012 standard requires VHT capable devices to be backward compatible with devices using which other 802.11 physical layer specification (PHY)?

Q77. In a mesh BSS (MBSS), according to the 802.11-2016 standard, what device connect the mesh to an Ethernet network?

Q78. You are troubleshooting a controller-based AP that is unable to locate the controller. DHCP is not use and the controller is located at 10.10.10.81/24 while the AP is on the 10.10.16.0/24 network. What should be inspected to verify proper configuration?

Q79. What statement describes the authorization component of a AAA implementation?

Q80. You have been tasked with creating a wireless link between two buildings on a single campus. The link must support at least 150 Mbps data rates. What kind of WLAN technology role should you deploy?

Q81. 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?

Q82. 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?

Q83. The requirement for a WLAN you are installing state that It must support unidirectional delays of less than 150 ms and the signal strength at all receivers can be no lower than -67 dBm.
What application is likely used that demands these requirements?

Q84. A company has hired you to perform a pre-deployment site survey of their facility. During an interview, the network manager informs you that the new wireless network must use 5 GHz bands and OFDM, and VoWiFi handsets will be used extensively over the wireless network.
What items do you need to include in the RF site survey report? (Choose 2)

Q85. ABC Company is planning a point-to-multipoint outdoor bridge deployment with standalone (autonomous) 802.11 bridge units. 802.1X/EAP will be used for bridge authentication. A Linux- based RADIUS server will be used for authentication. What device in the bridge Implementation as the 802.1X Authenticator?

Q86. What primary metric of scanning can stations use to select the best AP for connectivity to the desired BSS?

Q87. What best describes WPA2 in relation to 802.11 wireless network?

Q88. What information is transmitted in the Beacon management frames of an HT access point to communicate about backward compatibility with ERP and HR/DSSS stations? (Choose 2)

Q89. What statement is true concerning the use of Orthogonal Frequency Division Multiplexing (OFDM) modulation method in IEEE 802.11 WLANs?

Q90. Prior to association, what parameter can 802.11 client devices measure and use to select the optimal access point for association?

Q91. What factor will have the most significant impact on the amount of wireless throughput available to each station within a BSS?

Q92. An 802.11-based network uses an AP and has several connecting clients. The clients include iPhones, iPads, laptops and one desktop. What WLAN use case is represented?

Q93. When compared with legacy Power Save mode, how does VHT TXOP power save improve battery life for devices on a WLAN?

Q94. When a client moves to a new BSS within an ESS, what step is a part of the 802.11 reassociation process?

Q95. To ease user complexity, your company has implemented a single SSID for all employees.
However, the network administrator needs a way to control the network resources that can be accessed by each employee based on their department.
What WLAN feature would allow the network administrator to accomplish this task?

Q96. As a consultant, you’ve been hired by XYZ Company to provide recommendations about client device selection, operation, and interoperability. What information should be considered to help them choose the right WLAN client devices?

Q97. You manage a WLAN with 100 802.1lac access points. All access points are configured to use 80 MHz channels. In a particular BSS, only 40 MHz communications are seen. What is the likely cause of this behavior?

Q98. What statement is true concerning the use of Orthogonal Frequency Division Multiplexing (OFDM) modulation method in IEEE 802.11 WLANs?
