In a multitenant deployment with vManage hosting four tenants, how many vBond controllers are required?

In a Cisco SD-WAN multitenant deployment, a single vBond orchestrator can serve multiple tenants. The vBond's primary role is to authenticate and authorize SD-WAN devices (vEdges/cEdges) and facilitate the initial control plane connection to the vSmart controllers. This function is not tenant-specific and can be efficiently shared across tenants, making a single vBond sufficient and cost-effective. While redundancy for vBond is recommended in production environments (e.g., two vBonds for high availability), the question asks about the required number for a multitenant deployment, implying the minimum functional requirement. The options suggesting multiple vBonds per tenant or a fixed number like three are incorrect as vBond's role allows for sharing.
