Designing Cisco Enterprise Networks (ENSLD) — Question 128

What is the purpose of an edge node in an SD-Access network fabric?

Answer options

• A. Edge nodes identify and authenticate endpoints and register endpoint information with control plane nodes.
• B. Edge nodes track endpoint IDs to location mappings, along with IPv4, IPv6, or MAC addresses.
• C. Edge nodes are the gateway between the fabric domain and network outside of the fabric.
• D. Edge nodes resolve lookup requests from edge and border nodes to locate destination endpoint IDs.

Correct answer: A

Explanation

The correct answer, A, highlights that edge nodes are responsible for identifying and authenticating endpoints, which is crucial for network security and management. Options B, C, and D describe other functions that may involve edge nodes but do not capture their primary purpose within the SD-Access network fabric.
