Q50. You are using a site survey tool for post-implementation validation. You have installed the appropriate adapter driver and imported a floor plan. Now, you want to take the next step in proper tool use. What must you do before gathering survey data after the floor plan is imported?

Q51. What statement accurately describes the RF cables and connectors that are used in an
802.11 WLAN system?

Q52. What component of the 802.11 standard allows stations to reserve access to the RF medium for a specified period of time?

Q53. 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?

Q54. 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 acts as the 802.1X Authenticator?

Q55. You are configuring an access point to use channel 128. What important fact should be considered about this channel?

Q56. 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 5 GHz and 20 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?

Q57. What is an advantage of using WPA3-Personal instead of WPA2-Personal as a security solution for 802.11 networks?

Q58. Which directional antenna types are commonly used by indoor Wi-Fi devices in a MIMO multiple spatial stream implementation?

Q59. You are troubleshooting a client problem with a 2.4 GHz WLAN connection. The client is experiencing surprisingly low data rates during the work day. You analyze the workspace outside of business hours and detect a strong signal with a typical noise floor at the client location. During working hours, the user works with a laptop in the area and uses an external USB hard drive for continuous data access. The user also states that the laptop works as expected on her home network. The user working approximately 8 feet away from this client experiences no problems.
Based on this information, what is the likely cause of the problem?

Q60. You are troubleshooting a WLAN problem and you suspect hidden node as the cause. What should you look for in a protocol analyzers?

Q61. An IEEE 802.11 amendment is in the daft state. What impact does this draft amendment have on the 802.11 standard?

Q62. You are planning for PoE in a standard office deployment. Which one of these devices is least likely to be a PoE PD?

Q63. What statement about the IEEE 802.11e QoS facility is true?

Q64. 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?

Q65. You are evaluating access points for use in the 5 GHz frequency band. What PHY supports this band and supports 80 MHz channels?

Q66. What is required when operating 802.11ax APS in the 6 GHz band using passphrase-based authentication?
* VHT PHY

Q67. 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?

Q68. What feature(s) are most likely to be supported by 802.11 enterprise-class WLAN controllers?
(Choose 4)

Q69. 802. 11ax (HE) introduces Resource Units that can be used to allow communications with multiple devices at the same time, on the same channel, in the same BSS. What feature of 802.1 lax provides this functionality?

Q70. 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

Q71. Users and Network support personnel at a mid-sized equipment manufacturer have been discussing the potential uses and benefits of implementing an indoor WLAN. The network administrator and network manager have requested a meeting of senior management personnel to discuss a WLAN implementation before performing a site survey or taking any implementation steps. The first topic of discussion in the meeting is the corporate policy concerning implementation and use of WLAN technology.
What specific topics are appropriate in this policy meeting? (Choose 2)

Q72. What is always required to establish a high quality 2.4 GHz RF link at a distance of 3 miles (5 kilometers)?

Q73. What is appended to the end of each 802.11 data frame after the payload?

Q74. 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?
