A. Single-stream dual-band omnidirectional antenna

B. Double-flow single-frequency directional antenna

C. Double-flow dual-band directional antenna

A. The advantages of tunnel forwarding are: data flow and management flow all through the AC, it is easier for wireless users to implement security control strategy.

B. The management data of the AP in the tunnel forwarding mode is encapsulated in the tunnel of the CAPWAP protocol. The data business flow of the AP can be encapsulated in the CAPWAP tunnel or cannot be encapsulated in the CAPWAP tunnel.

C. In this networking figure, the AP adopts the tunnel forwarding mode. In the tunnel forwarding mode, the wireless user service data is encapsulated in the CAPWAP tunnel and forwarded between the AP and the AC. The port number of the tunnel is UDP 5246

D. Tunnel forwarding has two types of tunneling: controllable tunnels and traffic tunnels, where signaling packets take controllable tunnels, and data packets take traffic tunnels.

A. Scan terminal rate support

B. Warehouse vertical stereo channel planning

C. Warehouse Horizontal Planar Channel Planning

D. Sweep Terminal Channel Support

A. STA sends an association request to AP2 through channel 6, and AP2 responds with the association response to establish an association between the user and AP2.

B. STA sends the 802.11 disassociation information to the AP1 through the channel 6 (the channel used by the AP2), and the association between the user and the AP1 is released.

C. STA listens to each channel beacon and finds that AP2 satisfies the roaming condition and sends a probe request to AP2.

D. AP2 responds by sending a response on channel 6 (the channel used by AP2) after receiving the request in channel 6

A. Ensure that the AP is facing the target area

B. Try to install in a shelter

C. Minimize the number of signals passing through obstacles

D. AP is placed away from interference sources

A. one Jump relay between roots and leaves

B. two jumps relay between the roots and the leaves

C. root against four leaves

D. Roots against eight leaves

A. False

B. True

A. Network is divided into access layer, distribution layer and core layer

B. AP is connected to the access layer switch. It is recommended to use PoE switch

C. In the access layer can use the side of the box AC to achieve wireless centralized control function

D. AC can use the core switch built-in AC card to achieve

A. Rack slot resource tense scenario

B. The network scale is large and there is a need for further expansion in the future

C. Rack slot resource rich scenario

D. Small and medium-sized, integrated networking scenarios
