A logistics firm must block a merger-acquired site from learning data-center prefixes, allow all other sites full routes, and enforce this centrally without touching WAN Edges. Which centralized control policy action should the engineer configure to meet this routing requirement?
Select an answer to reveal the explanation.
Short Explanation
You're editing the guest list at headquarters before invitations go out. Filtering outbound keeps unwanted routes silent, so direction determines who learns what from the Controller.
Full Explanation
Centralized control policies manage OMP route advertisement and are configured on SD-WAN Manager and applied to SD-WAN Controllers, formerly vSmart, with direction relative to the Controller, where outbound means toward WAN Edges and can filter or modify prefixes per site-list, making it ideal for rejecting data-center routes only to the acquired site while preserving them elsewhere without Edge touches. A data policy controls forwarding path selection rather than route learning and applied on Edges would still propagate prefixes. App-aware routing influences path based on SLA and queuing but does not suppress route advertisement. Device access policy governs management-plane authentication to Manager, not OMP prefix distribution. For the exam, memorize control policy equals OMP filtering on the Controller with inbound from Edges and outbound to Edges. In practice verify policy direction, site-list membership, and show omp routes on both Controller and target Edge to confirm suppression.
