When expanding an existing Cisco SD-Access network, in addition to the control plane, which two device roles are needed to create an additional fabric site? (Choose two.)

The correct answer is A. leaf D. border. A Cisco SD-Access fabric site requires three functional roles: a control plane node (LISP map server/resolver, already given in the question), edge/leaf nodes, and border nodes. Leaf (fabric edge) nodes connect endpoint devices to the fabric - they register endpoint EIDs with the

Explanation

A Cisco SD-Access fabric site requires three functional roles: a control plane node (LISP map server/resolver, already given in the question), edge/leaf nodes, and border nodes. Leaf (fabric edge) nodes connect endpoint devices to the fabric - they register endpoint EIDs with the control plane and encapsulate/decapsulate VXLAN traffic. Border nodes connect the fabric site to external Layer 3 networks, other fabric sites, or shared services. Without at least one leaf and one border, the fabric site cannot admit endpoints or exchange traffic with the rest of the network. WLC (option B) is optional for wireless; cEdge (option E) is an SD-WAN construct, not an SD-Access fabric role.
