質問 # 178
What security protocol, mandated by the Wi-Fi Alliance, replaced WPA2 and introduced Simultaneous Authentication of Equals (SAE) as a replacement for the PSK four-way handshake?
正解：D
解説：
WPA3 is the current WLAN security certification from the Wi-Fi Alliance, and it introduced Simultaneous Authentication of Equals (SAE) as a replacement for the WPA2-Personal pre- shared key exchange. SAE, based on the Dragonfly key exchange protocol, protects against offline dictionary attacks by requiring an interactive exchange between the client and AP for each authentication attempt, unlike the older four-way handshake which could be captured and attacked offline. WPA3 also introduced mandatory Protected Management Frames (PMF).
質問 # 179
In a long-distance RF link, what statement about Fade Margin is true?
正解：D
解説：
Fade Margin is an additional pad of signal strength designed into the RF system to compensate for unpredictable signal fading. It is the difference between the receiver's sensitivity and the actual received signal level. A higher Fade Margin indicates a more robust link that can withstand interference, attenuation, or other factors that may reduce the signal strength. A lower Fade Margin means that the link is more susceptible to failure or performance degradation. Fade Margin is usually expressed in decibels (dB) and can be calculated by subtracting the receiver sensitivity from the received signal level. References: 1, Chapter 2, page 51; 2, Section 2.1
質問 # 180
In addition to coverage analysis results, what should be included in a post-deployment site survey report to ensure WLAN users experience acceptable performance?
正解：B
解説：
In addition to coverage analysis results, what should be included in a post-deployment site survey report to ensure WLAN users experience acceptable performance is Capacity analysis results.
Capacity analysis is a method of testing the ability of the WLAN to support the expected number and type of users, devices, and applications. Capacity analysis can help to determine the optimal number and placement of access points, the appropriate channel and power settings, the required QoS policies, and the expected throughput and latency levels. Capacity analysis results can help to verify that the WLAN meets the performance requirements and service level agreements (SLAs) of the organization.
質問 # 181
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 in their department.
What WLAN feature would allow the network administrator to accomplish this task?
正解：D
解説：
The WLAN feature that would allow the network administrator to control the network resources that can be accessed by each employee based on their department is Role-Based Access Control (RBAC). RBAC is a method of assigning different permissions and policies to users or groups based on their roles in the organization. RBAC can be implemented by using VLANs, ACLs, or firewalls to restrict access to certain network segments or resources. RBAC can also be integrated with 802.1X/EAP authentication to dynamically assign roles and VLANs to users based on their credentials.
質問 # 182
Which 802.11 frame is broadcast by a client station during active scanning to solicit responses from nearby access points?
正解：D
解説：
During active scanning, a client station transmits a Probe Request frame on each channel it scans, soliciting a response from any access points within range that match the requested SSID, or from all APs if the SSID field is left blank (a broadcast probe request). Access points that receive a matching Probe Request respond with a Probe Response frame, which contains similar information to a Beacon frame. Active scanning is typically faster than passive scanning, which only listens for periodic Beacon frames.
