350-401 Question #892: Real Exam Question with Answer & Explanation

Question

In a Cisco SD-Access network architecture, what is the role of the Fabric Edge Node?

Options

• AIt manages endpoint to device relationships
• BIt connects external layer 3 networks to the SDA fabric
• CIt connects wired endpoints to the SDA fabric
• DIt connects wireless endpoints to the SDA fabric

Explanation

In Cisco SD-Access, the Fabric Edge Node is a crucial component responsible for connecting wired endpoints to the SD-Access fabric, enforcing network policies, and extending segmentation.

Common mistakes.

• A. Managing endpoint-to-device relationships, particularly identity and policy assignment, is primarily handled by the Cisco Identity Services Engine (ISE), which integrates with the SD-Access fabric.
• B. Connecting external Layer 3 networks (e.g., enterprise data centers or the internet) to the SD-Access fabric is the role of the Fabric Border Node.
• D. Connecting wireless endpoints to the SD-Access fabric is achieved through Wireless LAN Controllers (WLCs) and their associated Access Points (APs), which are integrated into the fabric rather than being the Fabric Edge Node itself.
