300-415 Question 18
Single answerIn a Cisco SD-WAN deployment, what is the primary role of the vSmart controller with respect to the Overlay Management Protocol (OMP)?
- A
Establishing secure control plane tunnels with Cisco vEdge devices
- B
Distributing centralized data policies and routes to edge devices
- C
Providing direct communication with end-user devices for application traffic
- D
Acting as the data plane for forwarding user traffic between vEdge devices
Show answer and explanation
Correct answer: B
Explanation
The vSmart controller is the central control plane component in Cisco SD-WAN, responsible for managing and distributing routing, policies, and security information to edge devices using the Overlay Management Protocol (OMP). It ensures the network is dynamically updated and enforces business rules, but it does not perform data plane functions or interact directly with end-user devices.
- A. Incorrect.
While vSmart does establish secure control plane connectivity with edge devices, this is primarily the role of the vBond orchestrator. The primary function of vSmart is policy and route distribution using OMP.
- B. Correct.
This is correct. The vSmart controller is responsible for distributing centralized control, data, and application policies, as well as routing information across edge devices via the Overlay Management Protocol (OMP).
- C. Incorrect.
The vSmart controller does not interact directly with end-user devices or handle application traffic. Its role is largely restricted to control plane functions.
- D. Incorrect.
The vSmart controller is not part of the data plane. It facilitates route and policy distribution, while the data plane functionality is handled by edge devices like vEdge or cEdge.
