NO.268 When configuring VRRP hot backup, if the HSB backup function is enabled, and WLAN services are configured on the primary and secondary WACs in sequence, it may happen that VAPs have not been created on the secondary WAC, but VAP table information has been generated on the primary WAC.

NO.269 The application analysis function on the CampusInsight platform relies on the device to report traffic statistics to the platform. There are two ways to report device traffic statistics: NetStream- based reporting and application-based reporting. It is recommended to use NetStream-based reporting of traffic statistics.

NO.270 An engineer configures the smart roaming policy as follows. Which of the following configuration descriptions is wrong?

NO.271 In roaming scenarios, some terminals will not roam to an AP with better signal even if the AP forces them to go offline due to individual differences. Instead, they will “stubbornly” associate with the AP they last associated with, or even stop associating. For such terminals, WAC will directly kick them offline.

NO.272 When using built-in Portal authentication, the access device usually provides built-in Portal server function in HTTPS mode. If the access device is not configured with a trusted certificate, the client browser will not trust the default self-signed certificate of the access device and will pop up a security certificate warning message.

NO.273 Drag and Drop Question
Please match the following wireless network optimization modules with specific optimization methods.

NO.274 Drag and Drop Question
In the cloud WAC network, please sort the FITAP on-line process.

NO.275 In a WLAN network, which of the following descriptions of the network planning solution for the exhibition hall scenario are correct? (Multiple choice)

NO.276 In WLAN network planning, the final signal field strength is proportional to the AP transmission power and gain, and inversely proportional to the path loss and signal attenuation.

NO.277 In a Mesh network, the successful establishment of a Mesh link includes two processes: Mesh neighbor discovery and Mesh connection management.
Which of the following are the ways to discover Mesh neighbors? (Multiple choice)

NO.278 After the Huawei wireless controller enables the automatic RF tuning function, if the AP finds that the channel utilization is too high, the noise floor is too high, or the Beacon frame cannot be sent normally, it will report to the wireless controller to trigger local RF tuning.

NO.279 As terminals have higher and higher requirements for the service experience of WLAN networks, it is increasingly important to associate and connect terminals to appropriate APs. The terminal migration function can migrate terminals with poor service experience to appropriate APs based on the actual WLAN network environment to improve the terminal service experience. Which of the following technologies utilize the terminal migration function? (Multiple choice)

NO.280 In the WAC+FITAP networking scenario, CAPWAP tunnels support both IPv4 and IPv6 dual stacks. However, when deploying a WLAN network, it is not recommended to have both IPv4 APs and IPv6 APs in one area, otherwise it will affect services such as spectrum navigation, smart roaming, and load balancing.

NO.281 A customer’s existing network uses Huawei wireless controller to deploy 802.1x authentication, and the authentication server is iMaster NCECampus.
Engineers found that the terminal always failed authentication during the wireless network debugging process. What are the possible causes of this problem? (Multiple choice)

NO.282 In NaviAC networking, LocalAC and NaviAC cannot establish a CAPWAP tunnel. What are the possible causes of this failure? (Multiple choice)

NO.283 In WLAN networks, antenna gain is closely related to antenna radiation pattern. The wider the main lobe of the radiation pattern, the smaller the side lobe, the higher the gain, and the longer the distance of radio wave propagation.

NO.284 As shown in the figure, which of the following descriptions of the CampusInsight interface is correct?

NO.285 The SSID of a company’s WLAN network is “wlannet”. To prevent too many users from accessing and affecting the user experience, the network administrator configured user CAC. The user executed the display Rrm-profile name user-cac command on the AC, and the following result was displayed.

Which of the following descriptions of the echo information are correct? (Multiple choice)

NO.286 As shown in the figure, this is the floor plan of a luxury suite in a hotel. In order to save costs, the customer adopted a deployment solution in which a single AP covers two rooms.

If this deployment solution is adopted, in order to ensure the coverage effect, which of the following materials are not recommended for the middle wall? (Multiple choice)

NO.287 When the WLAN network project is delivered, you can use the Wi-Fi health check function in the ClouCampus APP to detect the current Wi-Fi network status. This function will be tested in many aspects, but which of the following aspects are not included?

NO.288 WLAN common tools WLAN Plarmer and CloudCampus APP are both web-based software and are fully open to the public. Users only need to register a Uniportal account to log in and use them.

NO.289 Which of the following factors should be considered when using outdoor AP for WLAN outdoor network planning? (Multiple choice)

NO.290 In the WLAN planning process, what is the primary consideration when choosing the frequency band (2.4 GHz or 5 GHz)?

NO.291 Which of the following data encryption algorithms is used in the WEP security policy?
