Which mode of Cisco FlexConnect is typically not recommended for operation?

Central switched mode in Cisco FlexConnect is typically not recommended for operation primarily due to its reliance on a central controller for processing client data traffic. In this mode, all user data traffic is forwarded to the controller, which can lead to increased latency and potential bottlenecks, particularly in environments with high data traffic or large numbers of users. This setup can also result in unnecessary strain on the controller's resources and may impact overall network performance.

In contrast, local switched mode allows the access point to handle data locally, reducing latency and improving throughput, especially for locally generated data. Dynamic AP mode focuses on optimizing the movement of access points between controller environments, providing flexibility. Broadband mode, although not widely used, is suited for specific scenarios where broadband services are desired.

Therefore, central switched mode's dependency on the controller for data is the key reason it is usually not the preferred operation mode in FlexConnect implementations.
