An engineer configures the spectrum navigation function on a wireless controller. The command line is as follows. Which of the following descriptions of the configuration command is wrong?
[WAC-wlan-view] r rm-profile name wlan rrm
[WAC-wlan-rrm-prof-wlan- r rm] band-steer balance start-threshold 20
[WAC-wlan-rrm-prof-wlan-rrm] band-steer balance gap-threshold 60
[WAC-wlan-rrm-prof-wlan-r r m] band-steer snr-threshold 20
[WAC-wlan-rrm-prof-wlan-rrm] band – steer deny-threshold 6
[WAC-wlan-rrm-prof-wlan – rrm] quit
- A . When the SNR in the 5G Probe sent by the terminal to the AP exceeds 20 dB, 5G access is given priority.
- B . When the number of users connected to the AP does not reach 20, new terminals will be given priority to access 5G
- C . When the number of users connected to the AP does not reach 20, the new online terminal initiates an association request using 2.4G, and the AP will reject its association. The maximum number of rejections is 6 times
- D . When the number of users accessing the AP exceeds 20, the proportion of 5G RF access users will be calculated. If it exceeds 60%, the newly launched terminals will be guided to access 5G first.
In LeaderAP networking mode, Layer 2 or Layer 3 roaming is supported but roaming between multiple LeaderAPs is not supported
- A . True
- B . False
In indoor non-high-density deployment scenarios (AP spacing of 10 to 15 meters), 5G networks can automatically identify service priorities, service throughput, and interference through a dynamic bandwidth selection algorithm, and prioritize allocating more network resources to high-load areas to improve user experience.
Please sort the following steps of the dynamic bandwidth selection algorithm according to the workflow
Through the spectrum navigation function, the AP can control the user terminal to access 5G first. However, once the number of access users of the AP reaches the starting threshold of the spectrum navigation 5G priority, the user terminal will be free to choose the access frequency band.
- A . True
- B . False
A customer’s existing network uses Huawei wireless controller to deploy 8O2.1x authentication, and the authentication server is iMaster NCECampus.
Engineers found that the terminal always failed authentication during the wireless network debugging process. What are the possible causes of this problem? (Multiple choice)
- A . The terminal and the authentication server are unreachable.
- B . The authorization key configured on the wireless controller is inconsistent with the authentication server configuration.
- C . Service VLAN is not configured on the wireless controller
- D . The authentication template configured on the wireless controller is not bound to the access template
The Airtime scheduling function is mainly used to schedule the wireless channel occupation time of each user to ensure that each user occupies the wireless channel relatively fairly.
As shown in the figure below, there are four users User1, User2, Uuser3 and USser4 in the transmission queue, and the four users currently occupy the channel for 5, 4, 6 and 7 times respectively.
When the Airtime scheduling function is turned on, which user will be prioritized next?
- A . User3
- B . User2
- C . User4
- D . User1
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
Please match the following NAC authentication methods with the applicable scenarios.
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? 
- A . ②④①③⑤
- B . ②⑤①③④
- C . ②④①⑤③
- D . ②⑤①④③
In a WLAN network, during the key negotiation phase of WPA/WPA2-PSK authentication, PMK can be generated in two ways. When the pre-shared key is a string, the pre-shared key is PMK.
- A . True
- B . False
