300-415 Question 113
Single answerYou are designing a Cisco SD-WAN deployment for an organization with multiple branch locations. The organization has a primary data center and two regional hubs that need to handle traffic aggregation and application services. The requirement is to minimize latency for branch-to-data-center communication while ensuring high availability and scalability. Which deployment approach best aligns with this requirement?
- A
Deploy regional hubs with vSmart controllers colocated at each hub and route all branch traffic through the primary data center.
- B
Deploy vEdge devices at both regional hubs and configure them for traffic aggregation and local breakout for internet traffic.
- C
Deploy regional hubs with centralized control plane elements (vSmart) at the primary data center and allow branches to connect directly to the regional hubs.
- D
Deploy vEdge devices only at the primary data center and configure branches to use the data center as the single aggregation point.
Show answer and explanation
Correct answer: C
Explanation
Deploying regional hubs with centralized control plane elements (vSmart) at the primary data center and allowing branches to connect directly to the regional hubs ensures a balanced approach. It reduces latency by leveraging regional hubs closer to the branches while maintaining centralized management for scalability and high availability. This design effectively meets the organization's requirements.
- A. Incorrect.
This option unnecessarily routes all branch traffic through the primary data center, increasing latency and creating a single point of failure. It does not align with the requirement for minimizing latency.
- B. Incorrect.
While this option provides some benefits for traffic aggregation and local breakout, it does not fully utilize regional hubs for branch-to-data-center communication and scalability.
- C. Correct.
This is the correct option as it minimizes latency by allowing branches to connect directly to regional hubs while centralizing control plane management at the primary data center, ensuring scalability and high availability.
- D. Incorrect.
This option introduces a single aggregation point at the primary data center, which does not meet the requirement for high availability and scalability.
