Correct answer: Converted by the AP to 802.3 and encapsulated into VXLAN.
Why this is the answer
In a fabric-enabled SSID, the AP acts as a fabric edge node. When a client connects, the AP converts the 802.11 wireless frames into 802.3 Ethernet frames. These Ethernet frames are then encapsulated into a VXLAN (Virtual Extensible LAN) tunnel. This VXLAN tunnel extends from the AP to the fabric border node, allowing the user traffic to be transported across the fabric overlay network. This approach offloads the centralized WLC from handling all user data traffic, improving scalability and performance. The incorrect options are: "Centrally switched back to the WLC and mapped to a VXLAN on the WLC" is incorrect because fabric-enabled SSIDs are designed to de-centralize data forwarding, not send all traffic back to the WLC. "Centrally switched back to the WLC and mapped to a VLAN on the WLC" is incorrect for the same reason and also because fabric uses VXLAN for overlay, not traditional VLANs for user traffic forwarding. "Converted by the AP to 802.3 and encapsulated into a VLAN" is incorrect because fabric-enabled SSIDs specifically use VXLAN for encapsulation to create the overlay network, not traditional VLANs.
