350-401 Question 37
Select 3A network administrator is deploying Cisco SD-WAN and needs to understand the roles of the control and data plane elements in the solution. Which of the following elements are part of the control plane in a Cisco SD-WAN architecture?
- A
vSmart controllers
- B
vEdge devices
- C
vBond orchestrators
- D
cEdge devices
- E
OMP (Overlay Management Protocol)
Show answer and explanation
Correct answers: A, C, E
Explanation
In Cisco SD-WAN architecture, the control plane elements include vSmart controllers, vBond orchestrators, and Overlay Management Protocol (OMP). These components manage routing, policies, and the establishment of secure tunnels between devices. vEdge and cEdge devices are data plane elements responsible for forwarding traffic and encryption.
- A. Correct.
vSmart controllers are part of the control plane as they manage policies, routing, and the overall control plane communication between SD-WAN devices.
- B. Incorrect.
vEdge devices are part of the data plane, not the control plane. They handle data traffic forwarding, encryption, and decryption.
- C. Correct.
vBond orchestrators are part of the control plane and manage initial device authentication and secure connectivity establishment between SD-WAN elements.
- D. Incorrect.
cEdge devices, like vEdge devices, are part of the data plane and handle data traffic forwarding and encryption.
- E. Correct.
OMP (Overlay Management Protocol) operates in the control plane, facilitating the exchange of routing and policy information between SD-WAN components.
