An engineer deploys APs to a branch office. All AP control and management-related traffic must be tunneled to a centralized WLC via CAPWAP. All user traffic must utilize the local Internet line. What

The correct answer is C. locally switched FlexConnect. Locally switched FlexConnect tunnels AP control and management traffic to a central WLC via CAPWAP while forwarding user data traffic directly through the local Internet connection at the branch.

Why each option

Locally switched FlexConnect tunnels AP control and management traffic to a central WLC via CAPWAP while forwarding user data traffic directly through the local Internet connection at the branch.

Awireless mesh network

A wireless mesh network addresses AP-to-AP backhaul connectivity for extending wireless coverage, not the separation of control plane and data plane traffic between a branch AP and a centralized WLC.

Bcentrally switched FlexConnect

Centrally switched FlexConnect tunnels both control and user data traffic back to the WLC via CAPWAP, which does not allow user traffic to exit through the local Internet line at the branch.

Clocally switched FlexConnectCorrect

In locally switched FlexConnect mode, the AP maintains a CAPWAP control tunnel to the WLC for management, configuration, and firmware operations, while client data frames are bridged locally at the branch - allowing the branch to use its local Internet line for user traffic. This split-plane design is precisely the requirement when control must remain centralized but user data must exit locally.

Da WLC in local mode

A WLC operating in local mode requires all client data traffic to be centrally switched through the WLC, making it impossible for user traffic to utilize the local branch Internet connection.

Concept tested: FlexConnect locally switched mode for split control and data plane
