1. Which of the following statements about load balancing algorithms is FALSE?
A) An AC calculates and compares load percentages of all radios in a load balancing group and obtains the smallest load percentage value.
B) 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).
C) 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%.
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.
2. When the STA uses the WPA2-802.1x security policy and supports fast roaming, the STA only needs to perform key negotiation, but does not need to pass 802.1x authentication again during roaming.
A) TRUE

D) Each AC must have a Master Controller specified.
4. In the dual-link cold standby load balancing networking shown in the figure, AP1 has gone online and set up the primary CAPWAP tunnel with AC1.
Which of the following are the possible time points will an active/standby switchover occur under normal circumstances after the primary CAPWAP tunnel between AP1 and AC1 is disconnected? (Multiple Choice)
