Which of the following statements about WLAN channel planning is correct? (Multiple choice)
- A . The United States can plan channels 1-13 in 2.4GHz
- B . Infrared interference needs to be considered during planning
- C . Radar interference needs to be considered during planning
- D . Avoid signal interference when planning
While designing signal coverage for a WLAN network planning project, which of the following issues should be considered and confirmed? (Multiple choice)
- A . AP deployment locations
- B . AP Antenna Selection
- C . Single-user bandwidth requirements
- D . Signal attenuation due to obstacles
In a WLAN network, if you want to configure the spectrum navigation function, the AP is required to support both the 2.4G band and the 5G band, and the two radio frequencies must use the same () and security policy.
Which of the following descriptions about preliminary planning before survey is correct? (Multiple choice)
- A . For indoor coverage scenarios, the number and location of APs can be preliminarily planned based on customer needs and drawings.
- B . During the initial planning, pay attention to the parts where the information is unclear, mark them, and focus on them during the on-site survey.
- C . Preliminary planning of outdoor bridges. You can use Google Earth to mark points and bridge paths to preliminarily assess feasibility.
- D . Preliminary planning of outdoor bridges, focusing on the distance between sites, altitude shielding and other conditions need to be paid attention to during on-site survey
An engineer is optimizing the wireless network on a customer’s live network. He logs in to the device to check the network status as follows. What problem can be determined by the following command line echo?
- A . The AP channel utilization is too high. It is recommended to perform radio frequency tuning.
- B . The AP’s two radio frequencies are unbalanced. It is recommended to enable the spectrum navigation function.
- C . The terminal signal strength is generally low, and there may be coverage issues
- D . The terminal rate is too low. It is recommended to change the AP working protocol to Wi-Fi6.

- B . AP8030DN
- C . AP8130DN
- D . AT815SN
WLAN air interface is a complex environment, and its performance is related to many factors. In addition to the co-frequency and adjacent-frequency interference between WLAN devices themselves, non-WLAN devices will also interfere with the WLAN air interface performance.
When deploying APs, you should avoid which of the following devices to prevent interference from affecting air interface performance? (Multiple choice)
- A . Wireless game controller
- B . Cordless phone with the same frequency band
- C . Bluetooth devices
- D . Microwave oven

- A . A maximum of 16 AC members can be added to a roaming group. The same WAC can join multiple roaming groups at the same time.
- B . Roaming group names must remain consistent between WACs
- C . When configuring a roaming group, ensure that the WAC has been configured with the CAPWAP source address, otherwise the roaming group will not take effect.
- D . WACs in the same roaming group must use the same software version, otherwise roaming between WACs may fail.
