（C）PEAP

（A）When the AP enables the hidden SSID function, it will only respond to the broadcast Probe Request message sent by the STA

（B）When the AP hides the SSID, the STA can only discover the services provided by the AP through active scanning

（C）There are two methods of active scanning and passive scanning, one client will only choose one method

（D）There are two types of Probe Request sent by STA: broadcast type and unicast type. The difference is whether the specific SSID name is carried in the message or not.

（E）Active scanning is implemented by the STA by monitoring the Probe Response message sent by the AP

（A）In the local forwarding mode, the STA service data will not be sent to the AC

（B）All data service packets between STAs need to pass through the AP, but do not need to be forwarded by the AC

（C）In the centralized forwarding mode, the data packets between STAs will also be sent to the AC through the tunnel. After being addressed by the AC, they will be encapsulated and sent back to the AP.

（D）In the local forwarding mode, the STA communicates directly through the 802.11 protocol without going through the AP

（A）WLAN optimization is a very good way to solve product problems

（B）WLAN optimization helps wireless networks become the perfect engine for customer business development

（C）WLAN optimization helps to implement wireless solutions in various scenarios

（A）Directional antenna at both ends

（B）One end of omnidirectional antenna, one end of directional antenna

（C）Omnidirectional antenna at both ends

（A）If the AP is placed in a waterproof box, the box must be firmly fixed and kept vertical: the box should be ventilated to facilitate the heat dissipation of the equipment: the box can be installed on the inner façade of the roof wall to block light In order to keep out the rain, all cables entering the waterproof box need to be waterproofed or routed downwards; the waterproof box can also be fixed on the pole used to install the antenna with a hoop.

（B）The AP installation location must meet the engineering design requirements. If the AP installation location needs to be changed, the approval of the design unit and the construction unit must be obtained, and the change procedures must be handled.

（C）The outdoor construction site should be easy to fix the device without obstruction; the building wall involved in the outdoor hardware installation should be firm and complete.

（D）Lightning protection and waterproofing must be done for outdoor equipment installation: Additional lightning protection devices are required for outdoor construction, such as lightning rods, ground stakes, grounding bars, etc. The AP surface should be perpendicular to the horizontal plane, and the outlet holes for wiring should be waterproofed Strict waterproof sealing measures should be taken at each joint.
