  A. An MP is also called Mesh gateway.
  B. An MP provides the Portal function and allows internal nodes to communicate with external networks.
  C. An MP supports automatic topology discovery, automatic route discovery, and data packet forwarding.

• Question 76:

  Huawei outdoor APs AP6510DN, AP6610DN, AP8030DN, and AP8130DN support access point mode and bridge mode.

  A. TRUE
  B. FALSE
  A. TRUE

• Question 77:

  On WLANs where many users exist, such as WLANs in high density scenarios, users compete fiercely to occupy channels as the number of online users increases. As a result, network quality deteriorates. To ensure network access experience of online users, Calling Access Control (CAC) can be configured. CAC allows an AP to control user access based on the CAC thresholds set according to the radio channel usage, number of online users on a radio, or terminal signal-to-noise ratio (SNR), ensuring network access quality of online users.

  A. TRUE
  B. FALSE
  A. TRUE

• Question 78:

  The AP detects whether the number of key negotiation failures of the key negotiation packets in the WPA/WPA2 PSK, WAPI-PSK, and WEP-Share-Key authentication exceeds the configured threshold to detect whether it is brute-forced.

  A. Correct
  B. False
  B. False

• Question 79:

  Which statement about linear networking of a Mesh network is FALSE?

  A. The neighbor can be manually specified.
  B. The neighbor cannot be manually specified.
  C. 802.11s packets converted from 802.3 packets can be transmitted over the links between MPs and then transmitted over wireless links.
  D. Single-point failures may occur.
  B. The neighbor cannot be manually specified.

• Question 80:

  Which of the following statements is TRUE about the DN parameter in the directory server?

  A. Each directory server has the DN parameter.
  B. Only the LDAP server has the DN parameter.
  C. The DN parameter needs to be manually configured by the directory server administrator.
  D. Only the AD server has the DN parameter.
  A. Each directory server has the DN parameter.
