Explanation:
The drag-and-drop mapping is based on the standard Cisco Catalyst SD-WAN component roles. vManage, now Cisco Catalyst SD-WAN Manager, provides centralized management, configuration, monitoring, templates, and operational visibility. vSmart Controller provides the centralized control plane, distributes OMP routing information, and applies control policy to determine reachability and path selection. vBond Orchestrator supports initial authentication, orchestration, and NAT traversal so WAN Edge devices can join the overlay. WAN Edge routers provide the data plane at branches, campuses, data centers, and cloud edges; they forward user traffic, establish secure tunnels, and apply localized policies. Correctly separating these roles is critical in the design because management, control, orchestration, and forwarding scale independently.
Misidentifying vBond as the data-plane element or vManage as the route controller would lead to an incorrect SD-WAN architecture. Reference topics: Cisco Catalyst SD-WAN components, vManage, vSmart, vBond, WAN Edge, OMP control plane. This role separation is also what lets large deployments scale without mixing troubleshooting, provisioning, and forwarding responsibilities on one system.

To support an IPv6 application across a dual-site, mixed Layer 2/Layer 3 network, all switches (both Layer 2 and Layer 3) participating in the VLAN must be capable of dual stacking to transport both IPv4 and IPv6 traffic.

Explanation
The EIGRP stub routing feature will prevent the remote device from advertising core routes back to the distribution devices. Routes learned by the remote device from Distribution 1 will not be advertised to Distribution 2. Therefore, Distribution 2 will not use the remote device as a transit for traffic destined to the network core
