300-415 Question 72
Select 3An enterprise is deploying a Cisco SD-WAN solution and is preparing to install the vManage, vSmart, and vBond controllers. The deployment will be hosted in a private data center, and the enterprise needs to ensure proper redundancy and scalability. What must the enterprise consider during the controller deployment process?
- A
vManage should be deployed with a minimum of three nodes in a cluster for redundancy.
- B
vBond must have a minimum of three instances deployed to support scalability.
- C
vSmart controllers should have at least two instances deployed for high availability.
- D
vManage and vSmart controllers can be deployed on the same virtual machine to save resources.
- E
All controllers must have valid certificates installed to establish secure communication.
Show answer and explanation
Correct answers: A, C, E
Explanation
In Cisco SD-WAN deployments, redundancy and security are critical. vManage requires a cluster of at least three nodes for redundancy, vSmart controllers need at least two instances for high availability, and all controllers must have valid certificates for secure communication. vBond does not require a minimum of three instances, and controllers cannot be deployed on the same virtual machine due to performance and operational constraints. Proper planning of these aspects ensures a scalable and reliable SD-WAN deployment.
- A. Correct.
Correct: For redundancy and scalability, vManage should be deployed as a cluster with at least three nodes. This ensures high availability and load balancing.
- B. Incorrect.
Incorrect: While vBond provides initial control-plane connectivity, it does not require a minimum of three instances for scalability. One or two instances are usually sufficient depending on the deployment size.
- C. Correct.
Correct: Deploying at least two vSmart controllers ensures high availability and supports failover in case one instance becomes unavailable.
- D. Incorrect.
Incorrect: vManage and vSmart controllers must be deployed on separate virtual machines to ensure proper functionality and scalability.
- E. Correct.
Correct: All SD-WAN controllers (vManage, vSmart, and vBond) must have valid certificates installed to establish secure and trusted communication within the SD-WAN fabric.
