300-415 Question 77
Select 3An enterprise is planning to deploy Cisco SD-WAN controllers (vManage, vSmart, and vBond) in their on-premises data center. Which of the following requirements must be met to ensure a successful deployment?
- A
Each controller must have reachability to all WAN Edge devices through public or private IP.
- B
The vBond orchestrator must be deployed with a public IP address or reachable via NAT.
- C
The vManage controller must be directly connected to the internet for software updates.
- D
All controllers must have certificates installed for secure communication.
- E
The vSmart controller must be deployed in a clustered configuration.
Show answer and explanation
Correct answers: A, B, D
Explanation
Deploying Cisco SD-WAN controllers on-premises requires that all controllers have proper IP reachability to WAN Edge devices for overlay communication. The vBond orchestrator plays a critical role in initial authentication and must be reachable via public IP or NAT. Certificates are essential to ensure secure communication between the controllers and devices. However, direct internet connectivity for vManage and clustering for vSmart are not mandatory requirements for a standard deployment.
- A. Correct.
Correct. All controllers (vManage, vSmart, and vBond) must have reachability to WAN Edge devices, either via public or private IP, to establish overlay communication.
- B. Correct.
Correct. The vBond orchestrator requires a public IP address or must be reachable through NAT to facilitate the initial device authentication and control connections.
- C. Incorrect.
Incorrect. The vManage controller does not need to be directly connected to the internet for software updates; updates can also be performed manually.
- D. Correct.
Correct. Certificates are mandatory for secure communication between controllers and devices in the Cisco SD-WAN solution.
- E. Incorrect.
Incorrect. The vSmart controller does not have to be deployed in a clustered configuration unless high availability is required, which is not a strict requirement for basic deployment.
