What are the prerequisites for Zero-Touch Provisioning to provision a new edge?

• A. Manual device configuration after boot.
• B. Initial lead time before a device can join.
• C. No central controller interaction needed.
• D. Prerequisites include initial reachability to vBond/vManage and configuration templates.

Answer: (D)

Zero-Touch Provisioning works by letting a new edge boot with minimal local configuration and then reach the SD-WAN control plane to receive its full setup. The essential prerequisites are that the edge can reach the orchestration components, specifically vBond and vManage, and that the necessary configuration templates are already stored in vManage. vBond handles initial authentication and helps the edge discover a path to vManage, while vManage holds the device templates, policies, and parameters that will be applied to the edge automatically. With these pieces in place, the edge can boot, authenticate, join the fabric, download its template, and configure itself without manual intervention. If reachability to vBond/vManage or the availability of templates is missing, provisioning cannot proceed automatically. Manual post-boot configuration isn’t part of ZTP, and there is no required lead time before the device can join when these prerequisites exist.
