A corporation is spread across different countries and uses MPLS to connect the offices.

 FlexConnect is a wireless solution for branch office and remote office deployments. It allows APs to switch data traffic locally and perform client authentication locally when their connection to the controller is interrupted. For the scenario described, where a corporation is spread across different countries and wants to minimize delays while ensuring strong connectivity, FlexConnect with central switching enabled is appropriate. This configuration allows traffic to be switched locally at the AP, reducing the amount of traffic traversing the MPLS network to the central WLC, thus minimizing delays. References := CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide
