質問 # 157
What networking component connects multiple access points together and to other networking infrastructure, such as a switch, allowing an Extended Service Set to function as a unified network?
正解：B
解説：
The Distribution System (DS) is the underlying network infrastructure, typically the wired Ethernet network, that connects multiple access points together within an Extended Service Set (ESS).
The Distribution System allows data frames to be forwarded between different APs, and out to other network resources, enabling a seamless roaming experience for client stations as they move between the coverage areas of different APs that are all part of the same ESS.
質問 # 158
What is the correct sequence of frame exchanges required for a client station to fully connect to an open, unencrypted 802.11 BSS?
正解：A
解説：
For a client station to connect to a BSS, it must first complete the 802.11 Authentication process, which for Open System authentication is a simple two-frame exchange that does not actually validate identity in a meaningful way. After successful authentication, the client sends an Association Request frame, and the AP responds with an Association Response frame if it accepts the connection. Only after both authentication and association are complete can the station begin exchanging data frames with the AP; for secured networks, the 802.1X/EAP or PSK key exchange process typically follows association.
質問 # 159
You are using a tool that allows you to see signal strength for all Aps in the area with a visual representation. It shows you SSIDs available and the security settings for each SSID. It allows you to filter by frequency band to see only 2.4 GHz networks or only 5 GHz networks. No additional features are available.
What kind of application is described?
正解：A
解説：
The tool described is a WLAN (Wireless Local Area Network) scanner tool. WLAN scanner tools are designed to provide information about the wireless networks in a given area, including:
* Signal Strength: They show the signal strength of all access points (APs) in the vicinity, which is crucial for understanding the coverage area and potential interference.
* SSID Visualization: These tools display the SSIDs (Service Set Identifiers) of available networks, allowing users to identify different wireless networks easily.
* Security Settings Information: WLAN scanner tools often show the type of security implemented on each network, such as WPA2, WEP, etc.
* Frequency Band Filtering: They allow users to filter and view networks based on the frequency band (2.4 GHz or 5 GHz), which is useful for analyzing network distribution and planning.
While protocol analyzers, site survey utilities, and spectrum analyzers are also used in wireless networking, their functions are distinct from what is described:
* Protocol Analyzersare more sophisticated and are used to capture and analyze network traffic.
* Site Survey Utilitiesare used to map signal coverage and plan network layouts, often with more advanced features for detailed site surveys.
* Spectrum Analyzersprovide a detailed view of the frequency spectrum and non-Wi-Fi interference but don't typically focus on SSIDs or security settings.
Thus, the correct answer is D, a WLAN scanner tool, based on the functionalities described.

質問 # 160
You are deploying a WLAN monitoring solution that utilizes distributed sensor devices. Where should sensors be deployed for best results? Choose the single best answer.
正解：D
解説：
Explanation:Sensors should be deployed in critical areas where WLAN performance must be high for best results when using a WLAN monitoring solution that utilizes distributed sensor devices. A WLAN monitoring solution is a system that collects, analyzes, and reports on the status and performance of a WLAN. A WLAN monitoring solution can use different methods to gather data from the WLAN, such as embedded software agents, external hardware probes, or distributed sensor devices. Distributed sensor devices are dedicated devices that are deployed throughout the WLAN coverage area to monitor the wireless traffic and environment. Distributed sensor devices can perform various functions, such as scanning the spectrum, capturing wireless frames, measuring signal quality, detecting rogue access points, testing connectivity, and generating alerts. Distributed sensor devices can provide more accurate and comprehensive data than other methods, but they also require more planning and deployment costs. Therefore, it is important to deploy sensors strategically in critical areas where WLAN performance must be high, such as high-density zones, high-priority applications, or high-security locations. By deploying sensors in critical areas, the WLAN monitoring solution can ensure optimal WLAN performance and reliability in those areas and identify and resolve any issues or problems that may arise. The other options are not the best places to deploy sensors for best results. Deploying sensors in switching closets is not effective because sensors need to be close to the wireless medium to monitor it properly. Deploying sensors every 5 meters and alongside each AP is not efficient because sensors may overlap or interfere with each other and cause unnecessary redundancy or complexity. Deploying sensors above the plenum on each floor is not practical because sensors may not capture the wireless traffic and environment accurately due to attenuation or reflection from the ceiling materials or objects.
質問 # 161
What primary metric of scanning can stations use to select the best AP for connectivity to the desired BSS?
正解：C
解説：
When a station scans for available wireless networks, it listens for beacon frames sent by APs. A beacon frame contains information about the BSS, such as SSID, supported rates, channel, security, etc. The station also measures the signal strength of the beacon frames, which indicates how well the station can communicate with the AP. The signal strength is usually expressed in dBm or RSSI units. The higher the signal strength, the better the connection quality and performance. Therefore, the station can use the signal strength of AP beacons as the primary metric to select the best AP for connectivity to the desired BSS.
