• Question 151:

  After the user CAC is enabled, the user is set to limit the number of users based on the channel usage. If the current channel usage exceeds the configured threshold, the AP will not only reject the association of the new terminal, but also kick the existing terminal off the line. Until the channel utilization is below the threshold.

  A. Correct
  B. False
  A. Correct

• Question 156:

  B. Home agent is either HAC or HAP
  C. Home agent is either HAC or FAP
  D. Home agent only exists in the AC roaming network
  A. Home agent is a device that can communicate with the gateway of the STA home network.
  B. Home agent is either HAC or HAP

• Question 157:

  Which of the following statements about the default HSB configuration are TRUE? (Multiple Choice)

  A. HSB is enabled.
  B. The number of retransmissions of HSB detection packets is 5.
  C. The retransmission interval of HSB detection packets is 5 seconds.
  D. HSB is disabled.
  B. The number of retransmissions of HSB detection packets is 5.
  D. HSB is disabled.

• Question 158:

  Which of the following statements about load balancing algorithms is FALSE?

  A. The load percentage of a radio is calculated using the formula: Load percentage of a radio = (Number of associated STAs on the radio/Maximum number of STAs allowed on the radio) x 100%.
  B. An AC calculates and compares load percentages of all radios in a load balancing group and obtains the smallest load percentage value.
  C. To determine whether to allow a STA to connect to an AP radio, an AC calculates the difference between the load percentage of the radio that the STA attempts to associate with and the smallest load percentage value, and compares the load difference with the threshold (configured using a command).
  D. If a STA continues sending association requests to an AP after an association request is rejected, the AP still rejects the STA association although the number of consecutive association attempts of the STA exceeds the maximum number of rejected association requests.
  D. If a STA continues sending association requests to an AP after an association request is rejected, the AP still rejects the STA association although the number of consecutive association attempts of the STA exceeds the maximum number of rejected association requests.

• Question 159:

  The following statement about the Mesh network is wrong?

  A. Protocol based on IEEE802.11m
  B. Not only can the user access function be provided, but also the wireless link signal can be forwarded.
  C. Multiple APs form a network structure
  D. The signal is routed from one AP to another within the network, and finally transmitted to the wired network through the AP connected to the fixed line.
  A. Protocol based on IEEE802.11m

• Question 160:

  Regarding the 802.1X authentication method, is the following description correct?

  A. 802.1X authentication mode is divided into EAP termination and EAP transparent transmission.
  B. EAP transparent authentication requires the NAS device to identify and resolve key information in the EAP and map it to the RADIUS packet to complete the entire authentication.
  C. EAP termination authentication does not require the NAS to resolve EAP packets. Instead, the EAP is encapsulated in RADIUS packets, so that authentication packets traverse the encapsulated network and reach the authentication server.
  D. EAP transparent authentication is also called EAP relay authentication.
  A. 802.1X authentication mode is divided into EAP termination and EAP transparent transmission.
  D. EAP transparent authentication is also called EAP relay authentication.
