300-415 Question 7
Single answerA company is planning to deploy Cisco SD-WAN in their network. They want to understand the purpose of each component in the Cisco SD-WAN architecture. Which component is responsible for centralized policy and control plane management in the architecture?
- A
vManage
- B
vSmart
- C
vEdge
- D
vBond
Show answer and explanation
Correct answer: B
Explanation
In the Cisco SD-WAN architecture, vSmart plays a critical role as the centralized controller for policy and control plane management. It ensures that policies are distributed and enforced across the SD-WAN fabric, enabling efficient and secure communication between devices. While other components like vManage, vEdge, and vBond serve essential roles in management, data forwarding, and orchestration respectively, only vSmart handles the centralized control plane and policy distribution.
- A. Incorrect.
vManage is a centralized management platform used for monitoring, configuration, and orchestration of the SD-WAN network. While important, it is not responsible for policy and control plane management.
- B. Correct.
vSmart is the centralized controller responsible for policy enforcement and the control plane in Cisco SD-WAN. It distributes control plane information and policies to devices in the SD-WAN fabric.
- C. Incorrect.
vEdge is a data plane component located at branch or edge sites. It is responsible for forwarding traffic and applying policies but does not handle centralized policy or control plane management.
- D. Incorrect.
vBond is the orchestration plane component responsible for authenticating SD-WAN devices and establishing secure connections between them. It does not manage policies or control plane functions.
