A company has deployed a centralized wireless architecture a their headquarters. In this type of deployment, to which network layer do you recommend that the WLC connect?

While the distribution layer aggregates uplinks from access switches, placing the WLC there adds unnecessary hops in the CAPWAP path and is not the recommended placement for a centralized headquarters deployment.

Data center layer is not a standard layer in the traditional three-tier campus network model (access, distribution, core) and is not a defined WLC placement tier in Cisco wireless design guidance.

Session layer refers to Layer 5 of the OSI model, which is a logical protocol layer, not a physical network infrastructure tier where a WLC can be connected.

In a centralized (also called unified or tunnel-based) WLAN deployment, all client traffic is encapsulated in CAPWAP tunnels from the APs to the WLC, so the WLC must be reachable at the same network tier where APs are connected. Placing the WLC at the access layer minimizes the number of hops in the CAPWAP tunnel path and ensures efficient traffic forwarding between APs and the controller. This placement supports the centralized model where the WLC handles all authentication, policy enforcement, and traffic switching.
