300-415 Question 42
Single answerYour organization has deployed a Cisco SD-WAN solution with multiple regional overlays (Multi-Region Fabric) to improve scale and segmentation. Region A and Region B are configured as separate domains, each with its own control plane. You are tasked with ensuring seamless communication between devices in Region A and Region B while maintaining independent control planes for each region. Which feature should you implement to achieve this?
- A
Cross-region Service Chaining
- B
Inter-region vSmart Peering
- C
Localized Data Plane Security
- D
On-demand TLOC Extension
Show answer and explanation
Correct answer: B
Explanation
In a Cisco SD-WAN Multi-Region Fabric, Inter-region vSmart Peering is the key feature that enables separate regional control planes to communicate. This ensures that data plane traffic can traverse between regions while maintaining independent control plane operations for scalability and segmentation. Other options like service chaining or TLOC extension do not address the requirement for control plane integration.
- A. Incorrect.
Cross-region Service Chaining is used for chaining services across regions but does not directly enable control plane communication between regions.
- B. Correct.
Inter-region vSmart Peering allows the control planes of different regions to communicate, enabling seamless data plane paths between regions while maintaining independent control planes.
- C. Incorrect.
Localized Data Plane Security enhances security within a specific region but does not address inter-region communication or control plane integration.
- D. Incorrect.
On-demand TLOC Extension is used to extend transport reachability but does not provide the control plane connectivity required for seamless communication between regions.
