350-401 Question #1347: Real Exam Question with Answer & Explanation

Question

In a Cisco SD-Access solution, which device connects wired endpoints to the fabric?

Options

• Afabric edge node
• Bfabric border node
• Cintermediate node
• Dcontrol plane node

Explanation

SD-Access Fabric Roles Explained

A fabric edge node is the device that connects wired endpoints (such as PCs, IP phones, and servers) directly to the SD-Access fabric, acting as the access layer switch where end devices physically plug in. It handles policy enforcement, endpoint registration, and VXLAN encapsulation for traffic entering the fabric.

Why the distractors are wrong:

• B (Fabric Border Node): Border nodes connect the SD-Access fabric to external networks (like the internet or traditional campus networks), not to end-user devices.
• C (Intermediate Node): This is an underlay transit device providing connectivity between fabric nodes - it has no direct role in connecting endpoints.
• D (Control Plane Node): This runs the LISP protocol to maintain the endpoint-to-location mapping database (like a directory service) - it's a logical role, not a point of endpoint attachment.

💡 Memory Tip: Think of the edge as the edge of the network where users live - just like the "edge" of a city is where people's homes are located. Edge = endpoints; Border = boundaries to outside networks.
