350-401 Question 38
Single answerAn organization has deployed Cisco SD-WAN in their network. During troubleshooting, the network administrator discovers that the SD-WAN control plane is not functioning correctly, which affects the ability of vEdge routers to exchange routing information. Which component is responsible for managing the SD-WAN control plane and should be investigated first?
- A
vManage
- B
vSmart
- C
vBond
- D
OMP (Overlay Management Protocol)
Show answer and explanation
Correct answer: B
Explanation
In Cisco SD-WAN, the vSmart controller is the core component of the control plane. It is responsible for managing routing policies and distributing them to the edge devices (vEdge). If the control plane is failing, the vSmart controller is the most likely component to investigate first. While vManage and vBond play critical roles in SD-WAN operations, they do not manage the control plane directly.
- A. Incorrect.
vManage is responsible for centralized configuration, monitoring, and management of the SD-WAN solution but does not directly handle the control plane.
- B. Correct.
vSmart is the control plane component of Cisco SD-WAN. It is responsible for managing routing and policy decisions and distributing this information to the vEdge routers. Any control plane issues should be investigated here first.
- C. Incorrect.
vBond facilitates the initial authentication and orchestration of devices in the SD-WAN fabric but does not manage the SD-WAN control plane.
- D. Incorrect.
OMP is a protocol used to exchange routing information, but it operates on the control plane under the management of the vSmart controller. OMP itself is not a standalone control plane component.
