Explanation

Cisco SD-WAN Multi-Region Fabric extends the secure overlay network across geographically diverse regions, providing end-to-end encryption to protect inter-region traffic.

Common mistakes.

A. 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.
B. 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.
C. 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.
