• Question 224:

  When the WLAN is covered outdoors, the following description is correct about the antenna hanging high?

  A. In order to ensure coverage of a larger area, the antenna should be as high as possible
  B. In order to ensure that there is no black under the tower, the antenna should be as low as possible.
  C. Directional antenna hanging height is not recommended more than 12m
  D. The omnidirectional antenna hanging height is recommended to exceed 12m

• Question 225:

  The following options are incorrect about the WLAN forwarding mode description?

  A. The WLAN forwarding model includes two modes: local forwarding mode and centralized forwarding mode.
  B. The data forwarding mode of the datagram is also called the tunnel forwarding mode. The service data packets are uniformly encapsulated by the AP and then forwarded to the AC.Line-to-AP management, also acting as a forwarding hub for AP traffic
