about 5G The working principle of priority, the following statement is correct ().

5G Priority request AP Is dual frequency AP Can work normally

5G Priority characteristics refer to 5G Client sends data first

5G After the priority is turned on, only support 2.4G The network transmission speed of the client will be slower

5G Priority request AP Is dual frequency AP Can work normally

5G Priority requires all clients to support at the same time

How to set the condition of switching trigger (). (Select 2 Answers)

Set current AP With neighbors AP Signal strength ratio, switch when reaching the threshold

Check the packet loss rate and start the handover when the packet loss rate reaches a certain value

when STA Yohara AP Start switching after reaching a certain distance

Set current AP With neighbors AP Signal strength ratio, switch when reaching the threshold

Check the packet loss rate and start the handover when the packet loss rate reaches a certain value

Yohara AP Start the switch when the network speed is very slow during association

Among the following options, () is the reason for using 5G priority access.

5G frequency band can provide better access capability and capacity

It is easier to make network planning in the 5G frequency band

5G frequency band can provide better access capability and capacity

The following statement about the AP access control method is incorrect ().(Select 2 Answers)

By default, the control method for AP to access AC is non-authentication

By configuring the AP in an offline state, authentication is required to automatically access

By default, the control method for AP to access AC is non-authentication

By configuring the AP in an offline state, authentication is required to automatically access

The configuration whitelist can be authenticated based on MAC or SN

If MAC authentication is used for AP access control, APs outside of the MAC authentication list can also go online after manual confirmation

About Huawei WLAN Description of the characteristics of the product, the following statement is correct ().

WLAN The switching threshold of load balancing has two configurations based on the number of users and the number of sessions.

Wireless controllers can achieve high availability through stacking

Huawei AP The radio frequency tuning function is divided into global tuning and local tuning. The local tuning is AP Done independently

WLAN The switching threshold of load balancing has two configurations based on the number of users and the number of sessions.

After dual-link backup is configured, if the user adopts the tunnel forwarding mode, even if it is active AC User services will not be interrupted after failure and restart

In the following options, () is not the main purpose of roaming.

Ensure that the user's network rate remains unchanged

Avoid long authentication time during roaming, resulting in packet loss or even business interruption

Ensure that the user authorization information remains unchanged

Guarantee users IP The address remains unchanged

Ensure that the user's network rate remains unchanged
