300-420 Question 230
Single answerAn enterprise is deploying Cisco SD-WAN to optimize its network. The team is discussing the roles of the different SD-WAN planes during the deployment. Which SD-WAN plane is responsible for establishing and maintaining secure connections between SD-WAN edges and controllers?
- A
Orchestration plane
- B
Management plane
- C
Control plane
- D
Data plane
Show answer and explanation
Correct answer: C
Explanation
The control plane in Cisco SD-WAN architecture is responsible for establishing and maintaining secure, encrypted control connections between the SD-WAN edges and vSmart controllers. These connections ensure secure communication and routing policy distribution. The other planes, such as orchestration, management, and data planes, have distinct roles but do not manage secure connections.
- A. Incorrect.
The orchestration plane is responsible for facilitating the initial connection of SD-WAN devices and distributing information about the network topology but does not directly manage secure connections.
- B. Incorrect.
The management plane provides centralized configuration and monitoring of the SD-WAN devices but does not establish secure tunnels between devices.
- C. Correct.
The control plane is responsible for establishing and maintaining secure, encrypted control connections between SD-WAN edges and controllers. It handles routing and policy enforcement decisions.
- D. Incorrect.
The data plane is responsible for forwarding user traffic across the network, but it does not manage secure connections or policies.
