Huawei HCIP-WLAN V2.0 認定 H12-323_V2.0 試験問題:

1. In Huawei's intelligent immersion solution, it is necessary to collect information about neighboring APs. The collection method only relies on the AP to listen to the Probe frame of the terminal, or the AP periodically switches channels and actively scans the terminal.

A) True
B) False

2. During the MAC authentication process, to prevent illegal users from brute-forcing the user name and password of the terminal, the silent function of MAC authentication can be enabled. By default, if a user fails to authenticate five times within 600 seconds, the access device will discard the user's authentication request within the next 60 seconds.

A) True
B) False

3. When there are many users in the WLAN network, such as in high-density scenarios, as the number of online users increases, the fierce competition for channels between users leads to poor Internet access quality for each user. In order to ensure the Internet access experience of online users, the user connection admission control (CAC) function can be deployed. Which of the following descriptions about the user CAC function is wrong?

A) CAC uses two thresholds to control the access of new users and roaming users respectively.
B) When a roaming user accesses the radio, the roaming user can access the radio as long as the roaming user threshold is not reached.
C) When a new user accesses, the AP checks whether the current number of users or the terminal signal-to-noise ratio reaches the threshold for new users. If so, the new user's access is denied and the SSID can be hidden.
D) When most users use the same service type and the service traffic is average, it is recommended to use the user CAC function based on terminal SNR.

4. An engineer configures the dynamic load balancing function on a Huawei wireless controller. The relevant command lines are as follows. Which options are correct regarding the description of the configuration command lines? (Multiple choice)

A) The above configuration is dynamic load balancing based on the number of users
B) If the terminal signal strength is lower than -70 DBm, the AP will directly filter the terminal information, will not report it to WAC, and will not be added to the dynamic load balancing group.
C) Dynamic load balancing will only be performed when the number of access users exceeds 20
D) Dynamic load balancing is enabled

5. Which of the following statements is false about STA roaming on a WLAN?

A) The STA access rights remain unchanged before and after roaming.
B) Users can perceive noticeable service interruption during STA roaming.
C) The STA's IP address remains unchanged before and after roaming.
D) Reauthentication does not necessarily happen during STA roaming.
