• Question 422:

  What is wrong about the load balancing algorithm described below?

  A. The load percentage is calculated by the formula (the number of users associated with the current RF / the maximum number of associated users supported by the current RF) ?100%
  B. Calculate the load percentage of all members in the equilibrium group and get the minimum value.
  C. Measure whether the allowed access is the difference between the percentage of the load of the AP radio that is pre-joined by the STA and the minimum value of the load percentage of all members, and compare this difference with the set load difference threshold (configured through the command line)
  D. If the STA continues to send an association request to the AP after rejecting the association, although the number of repetitions is greater than the set maximum number of rejection associations, the STA is eventually rejected.
  D. If the STA continues to send an association request to the AP after rejecting the association, although the number of repetitions is greater than the set maximum number of rejection associations, the STA is eventually rejected.
