In enterprise networking, WLANs are typically deployed at which layer to serve end-user connectivity?

• A. Access layer
• B. Core layer
• C. Distribution layer
• D. Data Center layer

Answer: (A)

WLANs are deployed at the edge of the campus network, at the access layer, because this is where end-user devices first connect to the network. Access-layer devices, such as wireless access points, provide the immediate link to users and endpoints, handle initial VLAN assignment and security policies, and apply QoS for client traffic. The distribution layer sits above to aggregate multiple access devices and enforce broader policies, while the core handles the fast backbone transport across the network. The data center layer focuses on servers and storage rather than user wireless access. Therefore, end-user connectivity through WLANs is best served at the access layer.
