Which SD‑WAN configuration construct provides day‑zero deployment and reusable configuration components?

Configuration groups are the correct answer because they are a key SD-WAN construct designed for day-zero deployment and for creating reusable configuration components. They allow administrators to define common configurations (like VPNs, policies, or features) once and apply them to multiple devices or device types, streamlining initial setup and ensuring consistency. Configuration via the vBond controller is incorrect because vBond's primary role is orchestration and authentication, not device configuration. Configuration through a Cisco Prime server is incorrect as Cisco Prime is a network management platform, but not the native SD-WAN configuration construct for day-zero and reusability. CLI-based templates are incorrect because while CLI templates can be used, configuration groups in SD-WAN provide a more structured, centralized, and automated approach to reusable configurations within the vManage NMS.
