300-415 Question 8
Single answerA company is planning to deploy a Cisco SD-WAN solution. During the design phase, you are asked to describe the purpose of the vSmart Controller within the Cisco SD-WAN architecture. Which of the following best describes its role?
- A
The vSmart Controller is responsible for managing the control plane and orchestrating policies across the SD-WAN fabric.
- B
The vSmart Controller is a data plane device that forwards traffic between branch sites.
- C
The vSmart Controller provides centralized management and configuration of SD-WAN devices.
- D
The vSmart Controller acts as a secure gateway for connecting users to cloud applications.
Show answer and explanation
Correct answer: A
Explanation
The vSmart Controller is a core component of the Cisco SD-WAN architecture and is responsible for the control plane. It establishes secure communication with vEdge/cEdge devices to distribute policies and routing information. Unlike vManage, which handles centralized management, or the data plane devices responsible for traffic forwarding, the vSmart Controller ensures policy enforcement and control plane functionality across the SD-WAN fabric.
- A. Correct.
Correct: The vSmart Controller manages the control plane and is responsible for orchestrating traffic policies, security policies, and routing decisions within the SD-WAN fabric.
- B. Incorrect.
Incorrect: The vSmart Controller does not participate in the data plane or directly forward traffic; this is the role of the vEdge or cEdge devices.
- C. Incorrect.
Incorrect: Centralized management and configuration of SD-WAN devices are handled by the vManage component, not the vSmart Controller.
- D. Incorrect.
Incorrect: Acting as a secure gateway for cloud connectivity is not the role of the vSmart Controller; this functionality is associated with the data plane devices (vEdge/cEdge) and cloud gateways.
