Correct answer: Provide connectivity to traditional Layer 3 networks..
Why this is the answer
A border node in Cisco SD-Access acts as the gateway between the SD-Access fabric and external networks, such as the internet, data center, or traditional enterprise networks. It performs route redistribution between the fabric's internal routing protocol (LISP) and external routing protocols (e.g., OSPF, EIGRP, BGP). "Connect users and devices to the fabric domain" describes the role of an edge node. "Group endpoints into IP pools" is a function of the Cisco Identity Services Engine (ISE) and the control plane, not the border node itself. "Provide reachability information to fabric endpoints" is primarily the role of the control plane node, which uses LISP to manage endpoint locations.
