Explanation
OSPF: SEGMENT, LINK STATE, TABLES
EIGRP: UNEQUAL PATH, DISTANCE VECTOR, METRIC

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:
-> 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.
