300-415 Question 11
Single answerAn enterprise is deploying Cisco SD-WAN in a branch office where the edge device is behind a NAT. The administrator is configuring the orchestration plane to ensure proper communication between the edge device and the controllers. Which role does the vBond orchestrator play in this scenario?
- A
Facilitates secure connectivity between edge devices and the vManage controller.
- B
Provides the initial point of authentication for edge devices and facilitates NAT traversal.
- C
Acts as the centralized management interface for SD-WAN policies and device configurations.
- D
Maintains a real-time database of all WAN edge devices and their connections.
Show answer and explanation
Correct answer: B
Explanation
The vBond orchestrator is a critical component of the orchestration plane in Cisco SD-WAN. It serves as the first point of authentication for WAN edge devices and ensures proper NAT traversal when devices are behind NAT. This allows the devices to establish secure communication with the control plane (vSmart) and management plane (vManage).
- A. Incorrect.
The vBond orchestrator does not directly manage connectivity between edge devices and vManage. Instead, it handles initial authentication and NAT traversal.
- B. Correct.
This is correct. The vBond orchestrator is responsible for authenticating WAN edge devices and facilitating NAT traversal to ensure secure communication with other controllers.
- C. Incorrect.
The vManage controller is the centralized management interface, not the vBond orchestrator.
- D. Incorrect.
This describes the function of the vSmart controller, which manages the control plane and maintains connectivity information.
