Huawei H12-321 Online Questions & Answers

• Question 111:

  Which of the following statements about the default configuration of common dual-link cold standby parameters is TRUE?

  A. The AC's global priority is 0.
  B. The AC's AP-specific priority is 0.
  C. Revertive switchover in dual-link backup mode is disabled.
  D. The dual-link backup function is enabled.
  A. The AC's global priority is 0.

• Question 112:

  Which of the following statements about precautions for HSB configuration is FALSE?

  A. When configuring dual-link HSB, you need to run the commit command on the active AC to deliver the configuration to APs after completing service configurations on both the active and standby ACs.
  B. When configuring dual-link HSB, you need to run the commit command on the active AC to deliver the configuration to APs after completing service configurations on the active AC. Then perform configurations on the standby AC.
  C. When configuring dual-link HSB, ensure that active and standby ACs deliver the same WLAN service configuration to an AP. If the configurations are inconsistent, the AP may not work properly after an active/standby switchover between ACs.
  D. During an active/standby switchover between two ACs, services forwarded through the tunnel may be interrupted because the switchover takes a long time. New users cannot go online and online users cannot roam between APs.
  B. When configuring dual-link HSB, you need to run the commit command on the active AC to deliver the configuration to APs after completing service configurations on the active AC. Then perform configurations on the standby AC.

• Question 113:
