Correct answer: to connect wired endpoints to the SD-Access fabric.
Why this is the answer
A fabric edge node in SD-Access is a device (typically a Cisco Catalyst switch) responsible for connecting wired endpoints to the SD-Access fabric. It performs host onboarding, applies policies, and extends the VXLAN overlay to the access layer. Connecting external Layer 3 networks to the SD-Access fabric is the role of a fabric border node. Advertising fabric IP address space to external networks is also a function of the fabric border node. The fusion router is an external device that provides shared services and connectivity to external networks, and it does not directly connect to the SD-Access fabric in the way an edge node does for endpoints.
