In a Cisco SD-Access network architecture, what is the role of the Fabric Edge Node?
The correct answer is C. It connects wired endpoints to the SDA fabric. In Cisco SD-Access, the Fabric Edge Node is a crucial component responsible for connecting wired endpoints to the SD-Access fabric, enforcing network policies, and extending segmentation.

Why each option
In Cisco SD-Access, the Fabric Edge Node is a crucial component responsible for connecting wired endpoints to the SD-Access fabric, enforcing network policies, and extending segmentation.
Managing endpoint-to-device relationships, particularly identity and policy assignment, is primarily handled by the Cisco Identity Services Engine (ISE), which integrates with the SD-Access fabric.
Connecting external Layer 3 networks (e.g., enterprise data centers or the internet) to the SD-Access fabric is the role of the Fabric Border Node.
The Fabric Edge Node, typically a Cisco Catalyst switch, acts as the ingress point for wired endpoints, connecting them to the SD-Access fabric. It registers endpoints with the control plane and applies security and segmentation policies defined in the SD-Access solution.
Connecting wireless endpoints to the SD-Access fabric is achieved through Wireless LAN Controllers (WLCs) and their associated Access Points (APs), which are integrated into the fabric rather than being the Fabric Edge Node itself.
