Which Is the only supported mode In NSX Global Manager when using Federation?

NSX Global Manager is a feature of NSX that allows managing multiple NSX domains across different sites or clouds from a single pane of glass. NSX Global Manager supports Federation, which is a capability that enables synchronizing configuration and policy across multiple NSX domains. Federation has many benefits such as simplifying operations, improving resiliency, and enabling disaster recovery.

The only supported mode in NSX Global Manager when using Federation is Policy mode. Policy mode means that NSX Global Manager acts as a policy manager that defines and distributes global policies to local NSX managers in different domains. Policy mode also allows local NSX managers to have their own local policies that can override or merge with global policies.
