  A. 3.3km
  B. 5.3km
  C. 7.3km
  D. 11.3km

• Question 286:

  Which of the following admission control information can be imported on the Agile Controller in batches? (Multiple Choice)

  A. Access device information
  B. Department information
  C. User information
  D. Authorization result
  E. Authorization element
  A. Access device information
  B. Department information
  C. User information

• Question 287:

  The AP periodically sends Discovery Request messages to check whether the original primary tunnel recovers. If the original primary tunnel recovers, the AP switches STA data back to this tunnel after a delay because this tunnel has a higher priority than the other one. To prevent frequent switchovers caused by network flapping, the AP requests ACs to perform revertive switchover after six Echo intervals, and then sends STA data to the new active AC.

  A. TRUE
  B. FALSE
  B. FALSE

• Question 288:

  Intelligent roaming, that is, the user is associated with a new AP from the original associated AP. This process is initiated by the user.

  A. Correct
  B. False
  B. False

• Question 289:

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

  A. In Discovery phase, after dual-link backup is enabled, an AP broadcasts a Discovery Request packet.
  B. 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.
  C. 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.
  D. 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. 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.
  C. 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.

• Question 290:

  After setting up tunnels with the active and standby ACs, the AP sends Echo messages to monitor tunnel status. The Echo messages contain the active/standby status of the tunnels. When the AP detects that the primary tunnel fails, it sends an Echo Request message with the active flag to the standby AC. After receiving the Echo Request message, the standby AC becomes the active AC, and the AP sends STA data to this AC.

  A. TRUE
  B. FALSE
  A. TRUE
