   A university's CMX HA pair experienced a failover, and the former active node is now back online. The administrator wants to restore the original active/standby roles without disrupting location services. What is the recommended recovery procedure?

   • AReboot the current active node to force it to fail over to the original active node.
   • BPerform a manual failover from the current active node back to the original active node during a maintenance window.
   • CReconfigure the original active node as a new standalone node and then re-add it to the HA pair.
   • DDo nothing; the roles will automatically revert after the original node re-synchronizes.
