In a WLAN network, management messages must be forwarded using a CAPWAP tunnel, while service data messages can be forwarded through a CAPWAP tunnel or direct forwarding.
- A . True
- B . False
The overall architecture of Huawei’s terminal dial-up test solution is shown in the figure below, where CampusInsight is the background analysis tool.
Which of the following descriptions about CampusInsight is wrong?
- A . Implement the data receiving backend server capability and be responsible for receiving and parsing the data reported by the APP
- B . Provide ratings and improvement reports
- C . Summarize and display the dial test data on the platform
- D . Link with the device and adjust the device parameter configuration according to the dial test report
In WAC+FITAP networking, what is the default interval for CAPWAP tunnel heartbeat detection? (Multiple choice)
- A . 10
- B . 15
- C . 30
- D . 25
Which of the following descriptions about VRRP hot backup and dual-link hot backup are correct? (Multiple choice)
- A . VRRP hot backup only supports active-standby networking, not load-sharing networking, while dual-link hot backup supports active-standby and load-sharing networking.
- B . During the VRRP hot backup active/standby switchback process, a smaller VRRP preemption delay time (usually less than 60 seconds) should be set to increase the active/standby switchover speed.
- C . In VRRP hot backup, the AP only establishes one CAPWAP tunnel, while in dual-link hot backup, the AP needs to establish two CAPWAP tunnels.
- D . VRRP hot backup supports backing up the IP address allocation information of the DHCP protocol, while dual-link hot backup does not support
The wireless air interface is a virtual logical interface on an AP or terminal. Many factors affect the performance of the wireless air interface, but which of the following factors is not included?
- A . Interference from non-WLAN devices
- B . Differences in terminal capabilities
- C . Switch forwarding capability
- D . Interference from WLAN equipment
The wireless air interface is a complex environment. The WLAN network experience is related to many factors. In addition to adjusting the networking, configuration, and working channels of the WLAN network itself, it is also necessary to adjust the parameter configuration of the wireless terminal.
Which of the following options are correct for describing client optimization methods? (Multiple choice)
- A . Configure the wireless adapter energy saving mode to the highest performance in the terminal power scheme
- B . Disable support for U-APSD power saving function
- C . Set the wireless terminal’s preferred frequency band to 5G
- D . Upgrade the terminal wireless network card driver to the latest version
In a WLAN network, the WLAN theoretical rate refers to the Wi-Fi air interface link establishment rate. Different Wi-Fi protocol standards correspond to different WLAN theoretical rates.
Which of the following factors affect the theoretical rate of WLAN? (Multiple choice)
- A . Number of effective subcarriers
- B . Symbol length and GI
- C . Bit rate
- D . Number of spatial streams
A government needs to deploy a WLAN network. The link authentication uses open system authentication, but the security requirements are extremely high. When engineers select security strategies, which of the following should they use first?
- A . WPA3-802.IX
- B . Static WEP
- C . WPA/WPA2-PPSK
- D . OWE
Which of the following options are correct for describing the spectrum navigation function? (Multiple choice)
- A . When the number of users accessing the AP reaches the starting threshold of spectrum navigation 5G priority, the 2.4G radio frequency is silent and the terminal is guided to access 5G
- B . Through the spectrum navigation function, the AP can control the terminal to access 5G first to reduce the load and interference on the 2.4G frequency band
- C . Before the number of AP users reaches the starting threshold of spectrum navigation 5G priority, priority access to the 5G frequency band
- D . The two frequency bands of the AP that implement the spectrum navigation function must use the same SSID and security policy
