Designing Cisco Enterprise Networks (ENSLD) — Question 191

What is one function of the vSmart controller in an SD-WAN deployment?

Answer options

• A. orchestrates vEdge and cEdge connectivity
• B. responsible for the centralized control plane of the SD-WAN network
• C. provides centralized network management and a GUI to monitor and operate the SD-WAN overlay
• D. provides a data-plane at branch offices to pass traffic through the SD-WAN network

Correct answer: B

Explanation

The correct answer is B because the vSmart controller is indeed responsible for the centralized control plane of the SD-WAN network, managing policies and routing. Option A is incorrect as it describes connectivity management rather than control plane functions. Option C, while accurate in describing the management aspect, does not capture the primary function of the control plane, and option D focuses on data-plane operations, which is not the role of the vSmart controller.
