In the Portal authentication scenario, the wireless controller is used as the access device and the Portal protocol is used to communicate with the Portal server. Which of the following descriptions of the Portal protocol is wrong?
- A . By default, the access device listens on port 2000.
- B . By default, the destination port number used by the device to actively send messages to the Porta1 server is 50100
- C . HTTP/HTTPS protocol can be used as Portal access protocol or Portal authentication protocol
- D . Portal protocol is based on TCP protocol for data transmission
In a WLAN network, starting from which of the following standards, it is possible to bundle 8 channels into 160 MHz, so that the transmission rate exceeds 1 Gigabit? (Multiple choice)
- A . A802.11ax
- B . 802.11a
- C . 802.11ac
- D . 802.11n
In a WLAN network, the working principle of a smart antenna is to receive signals transmitted by a terminal in an omnidirectional mode, determine the location of the terminal based on the received signal through a smart antenna algorithm, and then control the CPU to select a directional radiation mode in which the maximum radiation direction points to the terminal.
- A . True
- B . False
In the VRRP hot backup scenario, restart the master WAC and AP switching is normal. After the original master WAC completes the restart, all APs are in fault state and the service is interrupted.
Which of the following could be the cause of this problem?
- A . If the device is not configured with vrrp recover-delay, the restarted WAC may immediately become the master, resulting in a dual-master state.
- B . The CAPWAP address between the active and standby WACs does not use a virtual address
- C . Configuration synchronization is not enabled for the active and standby WACs
- D . HSB is not enabled
In WLAN networking, which of the following descriptions about GI are correct? (Multiple choice)
- A . GI refers to the protection interval between symbols, which is used to reduce the impact of interference.
- B . The larger the GI, the stronger the anti-interference ability
- C . The smaller the GI, the higher the transmission efficiency
- D . GI can be divided into normal GI and Short GI. When there are few interference factors in the indoor environment, it is recommended to use Short GI.
An engineer is deploying a wireless network. User access uses 802.1X authentication, the authentication point is the wireless controller, and the authentication server uses iMaster NCE-Campus.
The RADIUS authentication parameters are configured on the wireless controller as follows. Which of the following descriptions of the configuration are correct? (Multiple choice) 
- A . The device charges by duration, and the real-time billing function is not enabled
- B . Configure the accounting mode to RADIUS
- C . The RADIUS server address is 10.23.103.1
- D . RADIUS authentication and accounting port numbers are 1812 and 1813 respectively
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
In the CloudCampus APP, which of the following tools can be used to perform "attenuation testing" on site?
- A . AP Calculator
- B . Network Regulation
- C . Site Survey
- D . Acceptance
Which of the following statements about the principles of WLAN outdoor site deployment is correct? (Multiple choice)
- A . The site should be directly visible to the coverage area, and it is recommended that there should be no obstacles blocking the view.
- B . To ensure signal transmission, the site should be installed as high as possible
- C . Avoid strong electric and magnetic fields and other signal interference near the site
- D . There needs to be a reliable power supply near the site
Configuration optimization is mainly carried out on software features, and the user experience is improved by adjusting the configuration parameters of the wireless optimization function.
Which of the following wireless features can be used to improve the user network experience? (Multiple choice)
- A . Weak signal user access control
- B . Airtime Scheduling
- C . RF Tuning
- D . Smart Roaming
