- B . AP and AC exchange join messages
- C . AP and AC exchange image data packets
- D . AP and AC exchange keepalive packets

- A . 3
- B . 4
- C . 5
- D . 6
Four APs are deployed in a conference room that can accommodate up to 100 people. By configuring the CAC function on each AP, the number of users of a single AP cannot exceed 25, and the SSID will be hidden after exceeding. Thus, the effect of load balancing among APs is indirectly realized.
- A . True
- B . False
In a customer’s wireless network, Portal authentication is used for user authentication. The engineer configures Portal authentication on the Huawei wireless controller, involving Portal authentication templates, authentication-free templates, and authentication templates.
Which of the following descriptions about the certification-free template is wrong?
- A . When multiple authentication-free rules are configured at the same time, they can take effect cumulatively and match one by one
- B . The authentication-free template can invoke IPv4 ACL and IPv6 ACL
- C . The authentication-free template can only release the specified IP address through ACL calls
- D . Authentication-free authorization information is only valid for Portal authenticated users
Which of the following terminals is most suitable to use MAC authentication to access the wireless network?
- A . Windows PC
- B . Webcam
- C . Linux PC
- D . smartphone
A company needs to hold a temporary product launch event. Since there is no wired network foundation at the launch site and time is tight, the network engineer plans to use wireless Mesh networking.
Which of the following descriptions about deploying a Mesh network is wrong?
- A . Mesh links can be established between MPP and MP nodes in the Mesh network, and Mesh links can also be established between MP and MP nodes.
- B . Mesh link is usually recommended to use 5G radio frequency interface to establish, not recommended to use 2.4G radio frequency interface
- C . The Mesh link can use the DFS channel. When a radar signal is detected, the channel will automatically switch, and the wireless service will not be interrupted.
- D . When a new AP is added to the Mesh network, the AP can automatically discover the network topology and determine the best transmission path after it goes online
The Mesh network supports AP zero-configuration online, that is, the AP does not need to do any configuration on the AP and AC before going online, and the AP can go online after ensuring that the AP and AC network is reachable.
- A . True
- B . False
In a large-scale campus WLAN networking scenario, the administrator needs to manually configure a static IP address for the AP during the first step of going online.
- A . True
- B . False
