Single answerA company is migrating to Cisco SD-WAN and wants to ensure secure communication between its branch routers and the central provisioning system. Which plane in the Cisco SD-WAN architecture is responsible for authenticating and facilitating initial device onboarding to the network?
- A
Orchestration plane
- B
Management plane
- C
Control plane
- D
Data plane
Show answer and explanation
Correct answer: A
Explanation
In the Cisco SD-WAN architecture, the orchestration plane (typically represented by vBond) plays a critical role in onboarding new devices. It authenticates devices and acts as an intermediary to establish secure communication with the rest of the SD-WAN architecture. This ensures the network is secure and devices are properly provisioned before they operate within the SD-WAN environment.
- A. Correct.
The orchestration plane is responsible for secure onboarding of SD-WAN devices and facilitating their initial communication with the control plane. It ensures devices are authenticated and securely provisioned.
- B. Incorrect.
The management plane provides centralized configuration, monitoring, and policy management but does not directly handle device onboarding or authentication.
- C. Incorrect.
The control plane is responsible for routing information exchange and establishing control connections between routers, but it does not manage the onboarding process.
- D. Incorrect.
The data plane handles the actual forwarding of traffic between devices but is not involved in onboarding or authentication.
