Correct answer: end-to-end encryption for inter-region traffic.
Why this is the answer
Cisco SD-WAN Multi-Region Fabric extends the SD-WAN overlay across multiple geographical regions, enhancing scalability and resilience. A key capability it provides is end-to-end encryption for inter-region traffic. This ensures that data traversing between different SD-WAN regions remains secure and protected, maintaining data integrity and confidentiality across the distributed network. While SD-WAN generally offers SLA-aware routing, the Multi-Region Fabric specifically focuses on secure inter-region communication. Overlay support for IP multicast is a general SD-WAN feature, not exclusive to Multi-Region Fabric. Assigning a single vSmart controller to handle both region 0 and noncore regions is incorrect; Multi-Region Fabric uses a hierarchical vSmart architecture with dedicated vSmart controllers for different regions to ensure scalability and fault isolation.
