Explanation

Cisco SD-Access Wireless Fabric Explained

In SD-Access wireless deployments, the Access Point (AP) acts as a fabric edge node, making it part of the fabric overlay - it encapsulates wireless client traffic into VXLAN tunnels and forwards it into the SD-Access fabric, integrating seamlessly with the overlay network.

Why the distractors are wrong:

• A is incorrect because the AP is not part of the underlay; the underlay consists of the physical routers and switches providing IP connectivity between devices.
• B is incorrect because the Wireless LAN Controller (WLC) sits outside the fabric as a management/control-plane component, not as part of the underlay infrastructure.
• D is incorrect because wireless clients are endpoints that connect to the fabric through the AP, but they are not themselves fabric overlay participants - they remain unaware of the VXLAN encapsulation happening on their behalf.

Memory Tip: Think of the AP as the fabric's "wireless edge switch" - just as a wired edge switch is part of the overlay, so is the AP. The rule is: if it does VXLAN encapsulation, it's in the overlay. The AP encapsulates; the client does not.
