Designing Cisco Enterprise Networks (ENSLD) — Question 34

What is the purpose of a control plane node in a Cisco SD-Access network fabric?

Answer options

• A. to maintain the endpoint database and mapping between endpoints and edge nodes
• B. to detect endpoints in the fabric and inform the host tracking database of EID-to-fabric-edge node bindings
• C. to identify and authenticate endpoints within the network fabric
• D. to act as the network gateway between the network fabric and outside networks

Correct answer: A

Explanation

The control plane node's primary function is to maintain the endpoint database and manage the mappings between endpoints and edge nodes, which is essential for network operations. The other options describe functions related to endpoint detection, authentication, and gateway operations, which are not the main purpose of the control plane node.
