Which of the following SD-WAN features allows a router to be shipped directly to the installation site and does not require site-level configuration?

Zero-touch provisioning (ZTP) is a key SD-WAN feature that enables automated deployment and configuration of network devices. With ZTP, a new router can be shipped directly to a branch office, powered on, and then automatically connect to a central controller to download its configuration and necessary software, eliminating the need for on-site technical staff or manual setup.

Application-aware routing is an SD-WAN feature that intelligently routes traffic based on application performance and policy requirements, not for initial device setup.

Transport agnostic describes the SD-WAN's ability to use multiple underlying transport services (e.g., broadband, MPLS, LTE) for connectivity, which is a characteristic of the network architecture, not a provisioning method.

Central policy management allows administrators to define and apply network policies from a unified interface, but it relates to policy enforcement after deployment, not the initial automated configuration of a device.
