Which role does a fabric edge node perform in a Cisco wireless fabric architecture?

In a Cisco wireless fabric architecture, fabric edge nodes are responsible for terminating user data traffic at the network edge. These nodes act as the first point of contact for client devices, handling tasks such as encryption/decryption, VLAN tagging, Quality of Service (QoS) enforcement, and traffic forwarding to the appropriate destination within the fabric. The design centralizes control-plane functions in fabric control nodes, while edge nodes focus on data-plane operations to reduce latency and optimize network performance. Option A, authenticating TLS connections for management, is handled by management or control-plane components rather than edge nodes. Option B, enabling multicast snooping, is a network switch function but not a core responsibility of fabric edge nodes. Option D, converting Layer 2 to Layer 3 addresses, is part of routing functions and not a dedicated role of the wireless fabric edge node in client data processing. Cisco Wireless Core Technologies emphasize that by terminating user data at the edge, fabric edge nodes enable efficient traffic handling, secure processing, and scalable wireless deployment, which is critical in high-density enterprise environments.
