300-415 Question 80
Select 3An organization is planning to deploy Cisco SD-WAN controllers on-premises. Which of the following actions are necessary to ensure successful deployment and operation of the controllers?
- A
Configure the organization's DNS server to resolve the controller names to their IP addresses
- B
Set up public IP addresses for the controllers as they must always be reachable over the internet
- C
Install certificates on the controllers for secure communication
- D
Ensure that the vBond controller has a static public IP address or is NATed to a public IP address
- E
Deploy the controllers in the same geographic location for low-latency communication
Show answer and explanation
Correct answers: A, C, D
Explanation
In an on-premises Cisco SD-WAN controller deployment, DNS configuration (to resolve controller names), installing certificates (for secure communication), and ensuring the vBond controller has a public IP or NATed IP are critical steps. These ensure the operational readiness and security of the SD-WAN fabric. However, not all controllers require public IPs, and geographic colocation is optional based on latency requirements, not a strict deployment criterion.
- A. Correct.
DNS is required to resolve the controller names to their IP addresses for devices and other controllers to communicate properly.
- B. Incorrect.
While public IP addresses are needed for the vBond controller to be reachable, not all controllers require public IPs. This is not a mandatory step for all controllers in on-premises deployments.
- C. Correct.
Certificates are critical for secure communication within the SD-WAN fabric, ensuring authentication and encryption between components.
- D. Correct.
The vBond controller must have a public IP address or be NATed to one to facilitate secure connections with edge devices and other controllers.
- E. Incorrect.
Deploying controllers in the same geographic location may reduce latency but is not a strict requirement for on-premises deployments. Controllers can operate across different geographic locations if properly configured.
