Which Cisco SD-WAN feature enables centralized configuration management through reusable templates?

• A. Route reflectors
• B. BPDU filtering
• C. Device templates
• D. MPLS TE

Answer: (C)

Device templates enable centralized configuration management through reusable templates in Cisco SD-WAN. They let you define a set of configuration pieces—such as VPNs, interfaces, policies, and service profiles—in a single template, and then apply that template to multiple devices. This makes onboarding and provisioning consistent across sites, and when you update the template, those changes can propagate to all attached devices, keeping configurations uniform and reducing manual edits. Other options serve different purposes: route reflectors handle BGP route distribution, BPDU filtering controls switch-layer protocol behavior, and MPLS TE deals with traffic engineering in MPLS networks.
