300-415 Question 9
Single answerIn a Cisco SD-WAN deployment, the vBond orchestrator plays a key role in facilitating communication between SD-WAN components. Which of the following statements about vBond and its role in NAT traversal is correct?
- A
vBond is responsible for establishing secure data plane tunnels between SD-WAN edge devices.
- B
vBond uses a public IP address to facilitate NAT traversal and helps vEdges locate each other.
- C
vBond provides centralized policy enforcement for SD-WAN edge devices.
- D
vBond's primary role is to manage the application of QoS policies on SD-WAN traffic.
Show answer and explanation
Correct answer: B
Explanation
The vBond orchestrator plays a critical role in the Cisco SD-WAN architecture by facilitating NAT traversal and acting as an initial point of contact for all SD-WAN edge devices. It ensures that devices behind NAT can discover each other and establish secure communication. This capability is essential for seamless connectivity in environments where devices are deployed in private networks with NAT.
- A. Incorrect.
This is incorrect. The vBond orchestrator does not handle data plane tunnels; this is the responsibility of the vEdge devices. vBond's primary role is orchestration and NAT traversal.
- B. Correct.
This is correct. vBond uses a public IP address to facilitate NAT traversal and acts as the initial point of contact for SD-WAN edge devices. It helps them locate each other and establish communication.
- C. Incorrect.
This is incorrect. Centralized policy enforcement is a function of the vSmart controller, not the vBond orchestrator.
- D. Incorrect.
This is incorrect. The management of QoS policies is not a role of the vBond orchestrator but is handled by other SD-WAN components, such as vSmart or the edge devices.
