1. When dual-link HSB is configured, an AP sets up CAPWAP links with both the active and standby ACs.

A) TRUE
B) FALSE

2. Which of the following statements about the active CAPWAP link setup procedure are TRUE? (Multiple Choice)

A) If the AC priorities are the same, the AP compares the loads of the ACs, that is, the number of APs. The AP selects the AC connecting to fewer APs as the active AC.
B) After receiving the Discovery Response packets, the AP selects an active AC based on AC priorities, loads, and IP addresses and sets up an active CAPWAP link with the active AC.
C) In Discovery phase, after dual-link backup is enabled, an AP broadcasts a Discovery Request packet.
D) As long as the active and standby ACs work properly, they will return Discovery Response packets to the AP. The Discovery Response packets contain the dual-link backup flags, priorities, loads, and IP addresses of the ACs.

3. During global radio calibration, the AC runs () and () algorithms according to the AP neighbor relationship, interference, and load information to generate new transmit power and working channels and delivers them to APs. (Multiple Choice)

A) CAC
B) TPC
C) DCA
D) EDCA

4. Which statement about Mesh roles is TRUE?

A) Mesh roles are configured based on radio.
B) Mesh roles are configured based on VAP.
C) Mesh roles are configured based on any conditions.
D) Mesh roles are configured based on AP.

5. 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.
