質問 3

A company needs to provide Wi-Fi coverage spanning a radius of about 100 m in a flat outdoor area. In the center of the area, APsand 2.4 GHz omnidi recto id i antennas (11 dBi gam and 15° vertical beam width) are installed on the top of a six-story building. A laptop 70 m away from this building cannot receive Wi-Fi signals. Which of the following statements is true about the cause analysis and solution for this symptom?

A. The antenna angle is small. The solution is to adjust the angle of the antennas.

B. The antennas arc installed too high. The solution is to move the antennas to a lower position.

C. The antenna gain is too low to cover such a distance. The solution is to replace the antennas with higher- gain ones.

D. The performance of the laptop ' s network adapter is poor. The solution is to replace the laptop.

正解: B

質問 5

In mesh networking, APs have different roles. Drag the AP roles on the left to the role descriptions on the right.

正解:

Explanation:
* MP: Mesh node that uses IEEE 802.11 MAC and PHY protocols for wireless communication. This node supports automatic topology discovery, automatic route discovery, and data packet forwarding. It can provide both mesh service and user access service 1 .
* MPP: MP node that connects a WMN to MPs on other types of networks. This node can function as a portal for communication between internal mesh nodes and external networks 1 .
* Neighbor MP: Neighboring MP with which an MP prepares to establish a mesh link 1 .
* Candidate MP: AP that directly communicates with a mesh node 2 .
