The top SD-WAN benefits are: + Increased bandwidth at a lower cost + Centralized management across branch networks + Full visibility into the network + Providing organizations with more connection type options and vendor selection when building a network. Reference: https://www.sdxcentral.com/networking/sd-wan/definitions/sd-wan-technology/ -> We can provision endpoints (vEdges) through a centralized router vManage -> Answer D is correct. Answer A is not correct as we can use different kind of connections on SD-WAN: MPLS, LTE, 4G, xDSL, Internet connections... Application-Aware Routing policy is configured in vManage as a centralized data policy that maps the service- side application(s) to specific SLA requirements. The centralized policies provisioned in vSmart controller is pushed to relevant WAN Edge devices for enforcement. The defined policy consists of match-action pairs, where the match statement defines the application-list or the type of traffic to match, and the action statement defines the SLA action the WAN Edge devices must enforce for the specified traffic.
