The load balancing function is mainly applicable to scenarios with high AP coverage overlap, such as lecture halls. By configuring the load balancing function, some terminals can be migrated to APs with relatively light loads. However, if the load balancing parameters are not configured properly, frequent terminal migration may occur.
- A . True
- B . False
In a project, two points are 4.5 km apart. In order to transmit data between the two points, which of the following information do engineers need to collect? (Multiple choice)
- A . Bandwidth requirements
- B . Obstacle information between two points
- C . 2.4G channel usage between two points
- D . 5G channel usage between two points
- E . Terminal type
WLAN Planner supports batch export when managing projects, and can export up to 10 records at a time
- A . True
- B . False
The license file of Huawei wireless controller is bound to the equipment serial number (ESN), that is, the license file is unique and corresponds to the device.
- A . True
- B . False
Which of the following descriptions about PMK fast roaming are correct? (Multiple choice)
- A . PMK fast roaming supports WPA3-802.1X or WPA2-802.1X authentication methods
- B . PMK fast roaming does not require re-authentication and key negotiation, thus reducing roaming delays
- C . PMK fast roaming requires the client to support fast roaming technology
- D . PMK fast roaming is achieved through pairwise master key PMK caching technology
In agile distributed networking, which of the following are common network elements of WLAN networks? (Multiple choice)
- A . Remote Unit
- B . WAC
- C . Switch
- D . Central AP
In the scenario of WLAN outdoor WDS deployment, the trees in the middle have little effect on signal attenuation, so the factor of trees in the middle can be ignored during network planning?
- A . True
- B . False
RF tuning is a RF resource management solution that enables wireless networks to quickly adapt to changes in the wireless environment. Which of the following does the RF tuning process not include?
- A . Channel Adjustment
- B . Neighbor Detection
- C . Load Balancing
- D . Power adjustment
To prevent non-critical services from occupying too much network resources, QoS policies can be configured in application protocols, namely smart application control SAC.
Which of the following descriptions of SAC functions is wrong?
- A . SAC mainly detects and identifies the 4th to 7th layer content and some dynamic protocols (such as HTTP, RTP) in the message, and implements refined QoS policy control based on the classification results
- B . For the identified application protocol packets, their priority can be modified or directly discarded
- C . In roaming scenarios, the SAC policy of the user after roaming is based on the policy issued by the device accessed after roaming.
- D . When a CAPWAP tunnel is established between WAC and AP to centrally forward user messages, the SAC service will be deployed on the AP.
A customer is deploying Huawei’s cloud management solution on their existing network. All cloud APs are now online, but all APs are working on the same channel, causing serious interference.
When engineers trigger radio frequency calibration on the cloud platform, they find that the calibration does not take effect. Which of the following reasons may cause radio frequency calibration of cloud APs to fail to take effect? (Multiple choice)
- A . Cloud APs belong to different sites
- B . The Leader group is not established.
- C . Channel or power configuration is fixed mode
- D . The AP is not tuned.
