   A global company is deploying SD-WAN across its regional offices. Each office has a 200 Mbps MPLS link and a 500 Mbps internet link. The company uses a real-time collaboration suite (video and voice) that requires 50 Mbps with low latency, a CRM system that requires 30 Mbps, and a large data replication service that requires 150 Mbps. The collaboration suite and CRM are critical, while data replication is not. The company also has a requirement to keep all traffic within the region for data sovereignty. What is the most appropriate bandwidth plan for each regional office?

   • ARoute collaboration and CRM over the MPLS link, and data replication over the internet link, with QoS prioritizing collaboration and CRM.
   • BRoute data replication over the MPLS link, and collaboration and CRM over the internet link.
   • CRoute all traffic over the MPLS link, and use the internet link only for failover.
   • DRoute collaboration over the internet link, and CRM and data replication over the MPLS link.
