300-415 Question 70
Select 3You are deploying Cisco SD-WAN controllers in a hybrid cloud environment. The design requires you to ensure high availability for the vSmart controllers while minimizing latency between them and edge devices in geographically dispersed branch locations. Which combination of deployment strategies should you implement?
- A
Deploy vSmart controllers across multiple data centers in active-active mode.
- B
Deploy all vSmart controllers in a single data center with redundant hardware.
- C
Place vSmart controllers in regions closest to the majority of branch locations.
- D
Ensure vSmart controllers are deployed behind a Network Address Translation (NAT) device.
- E
Use a minimum of three vSmart controllers to ensure redundancy.
Show answer and explanation
Correct answers: A, C, E
Explanation
To deploy Cisco SD-WAN controllers effectively in a hybrid cloud environment, it is essential to balance redundancy, high availability, and low latency. Deploying vSmart controllers across multiple data centers in active-active mode ensures availability and load distribution. Placing them in regions close to branch locations minimizes latency, and using at least three vSmart controllers ensures redundancy in case of failure. These strategies together align with Cisco's SD-WAN best practices for controller deployment.
- A. Correct.
Deploying vSmart controllers across multiple data centers in active-active mode ensures high availability and load balancing, which is crucial for minimizing latency and maintaining redundancy.
- B. Incorrect.
Deploying all vSmart controllers in a single data center with redundant hardware might address hardware failure but does not minimize latency for geographically dispersed branches or provide geographic redundancy.
- C. Correct.
Placing vSmart controllers closer to the majority of branch locations reduces latency and improves performance for edge devices communicating with the controllers.
- D. Incorrect.
Deploying vSmart controllers behind a NAT device is not a requirement for controller deployment and does not directly address high availability or latency reduction.
- E. Correct.
Using at least three vSmart controllers ensures high availability and redundancy, as the SD-WAN architecture relies on having multiple controllers for failover and scalability.
