In the RF tuning solution, which of the following descriptions about the dynamic frequency band adjustment function is wrong?
- A . When the redundant radio is switched to 5G, its channel is the default 5G channel.
- B . During the dynamic frequency band adjustment process, once the vulnerability detection mechanism detects that the 2.4G radio has a coverage vulnerability, the switched 5G radio will switch back to the 2.4G radio.
- C . Mainly for automatic identification and adjustment of Yuanyu 2.4G radio frequency
- D . If the dynamic frequency band adjustment function is turned off, the remaining radios will maintain the current working mode
In a WLAN network, what are the following advantages of using a PoE switch for power supply compared to using a PoE power adapter for power supply? (Multiple choice)
- A . APOE switch equipment costs less
- B . No external power supply, more beautiful when deployed
- C . Reuse network cable power supply to reduce construction costs
- D . PoE port can be remotely managed
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
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)
- A . Smart Roaming
- B . User CAC
- C . Load Balancing
- D . Spectrum Navigation
Portal authentication is also commonly known as Web authentication. The Portal authentication system is mainly composed of three basic elements: client, access device and Portal server.
- A . True
- B . False
WLAN agile distributed networking includes network elements such as WAC, central AP and RU. WAC manages central AP and RU in a unified manner. RU and the central AP to which it connects must be reachable on the Layer 2 network, while WAC and central AP and RU can be reachable on the Layer 2 or Layer 3 network.
- A . True
- B . False
The weak signal terminal access control function mainly controls terminal access by configuring the terminal access signal-to-noise ratio threshold. If the configured signal-to-noise ratio threshold is 25dB and the wireless network noise floor is -95dBm, when the terminal’s channel strength is lower than () dBm, that is, lower than the signal-to-noise ratio threshold, the terminal cannot access the network.
In WLAN networks, network planning and design are usually optimized for which of the following issues? (Multiple choice)
- A . Severe co-channel interference
- B . The terminal has slow Internet access speed
- C . The VIP area experience advantage is not obvious
- D . Weak signal strength
In a WLAN network, users can use the Wi-Fi test function in the CloudCampus app to test the wireless network and services.
Among them, Wi-Fi health check can enable Jie to comprehensively detect the Wi-Fi network status from which of the following aspects? (Multiple choice)
- A . Business Experience
- B . Cybersecurity
- C . Wi-Fi stability
- D . Coverage test
Which of the following networking methods are recommended by MSH planning? (Multiple choice)
- A . Shaped Network
- B . Chain Networking
- C . Type Networking
- D . Elliptical Network
