Q297. Multicast messages are sent at a low rate on the air interface. A large number of such messages will occupy a large amount of air interface resources, affecting the transmission of normal user service data packets. In scenarios without multicast services, when the service data forwarding method adopts tunnel forwarding, it is recommended to configure multicast message suppression on WAC. Which of the following configuration commands for the multicast packet suppression function is correct?

Q298. On a network where Huawei’s traditional WLAN solution is deployed, all APs are managed by a WAC. If users encounter STA roaming failures and a deteriorating WLAN service experience, which of the following is not the possible cause of this problem?

Q299. In the wireless coverage scenarios of wards and clinics, engineers proposed two network planning solutions as shown in the figure.

Which of the following descriptions of these two solutions are correct?

Q300. In the WLAN network optimization solution, configuration optimization mainly adjusts the parameters that affect the network experience-related functions, including radio frequency parameter adjustment, authentication strategy optimization, security strategy optimization, etc.

Q301. The load balancing function is mainly applicable to scenarios with high AP coverage overlap, such as lecture halls. By configuring the load balancing function, some terminals can be migrated to APs with relatively light loads. However, if the load balancing parameters are not configured properly, frequent terminal migration may occur.

Q302. The antenna configuration of MIMO is usually expressed as “M * N”, where M and N represent?
(Multiple choice)

Q303. When optimizing wireless network planning, it is also necessary to collect wired network data, including network architecture, key equipment configuration and operating status, etc.

Q304. Which of the following descriptions about the AC networking mode included with the board is wrong?

Q305. A company has deployed multiple APs in its office area. To improve the convenience of network deployment, the user hopes that WAC will automatically assign channels to APs based on the wireless network environment, so the RF tuning function is configured. However, engineers found that the RF tuning did not take effect. Which of the following configurations might be the cause?

Q306. Radio frequency mainly uses spread spectrum technology. Which of the following technologies belong to spread spectrum technology? (Multiple choice)

Q307. In a WLAN network, when the AP’s transmit power is 100mW, how many dBm is equivalent?

Q308. In the WLAN network intelligent roaming scenario, WAC will select the target AP that triggers the terminal to roam based on factors such as signal-to-noise ratio, access rate, and load balancing.
The figure shows the selection process of the roaming target AP when the terminal supports the
802.11k protocol. Which of the following is correct?

Q309. A large enterprise needs to deploy a VLAN network in the office environment to provide employees with services such as wireless Internet access, wireless office and wireless roaming.
The enterprise hopes to control costs as much as possible while meeting the needs and taking into account the unified management of wired and wireless networks. Which of the following networking methods is the best?

Q310. Which of the following are common faults in WLAN networks? (Multiple choice)

Q311. In medical scenarios, since wards, clinics and other areas are composed of multiple isolated small rooms, panel APs or agile distributed RUs can be used to cover each small room.

Q312. Which of the following tools can be used when using CloudCampus APP for project delivery?
(Multiple choice)
