Which capability does Cisco SD-WAN Multi-Region Fabric provide?

End-to-end SLA-aware routing is a general capability of Cisco SD-WAN, not a unique or distinguishing feature of the Multi-Region Fabric specifically, which focuses on inter-region connectivity and scale.

While Cisco SD-WAN can support overlay IP multicast, it is not highlighted as a primary or unique capability of the Multi-Region Fabric feature itself.

This statement is incorrect; the Multi-Region Fabric architecture specifically employs multiple vSmart controllers, including dedicated ones for region 0 (core) and non-core regions, to distribute control plane load and enhance scalability.

The Cisco SD-WAN Multi-Region Fabric extends the secure overlay network across multiple geographical regions, and a fundamental capability is providing end-to-end encryption to ensure secure communication for all traffic, including inter-region traffic. This secure segmentation is a core design principle for multi-region deployments.
