A Layer 2 trunk is configured to interconnect the two environments.
The customer also builds ACI fabric in an application-centric mode.

When migrating from a legacy environment to Cisco ACI, it is important to ensure that the migration is done smoothly to reduce the risk of instability in the network. One way to achieve this is by configuring the bridge domain with the appropriate settings.
In this scenario, the customer has configured a Layer 2 trunk to interconnect the two environments and has also built an ACI fabric in application-centric mode. To reduce instability during the migration, the recommended feature to enable in the bridge domain is "Multi-Destination Flooding" set to "Flood in Encapsulation."
Multi-Destination Flooding is a feature that allows for the efficient distribution of broadcast, multicast, and unknown unicast traffic within the ACI fabric. When enabled, the ACI fabric floods the traffic to all the ports in the bridge domain, which helps ensure that the traffic is delivered to all the endpoints that need it.
Flood in Encapsulation is a setting that specifies whether to flood multicast and unknown unicast traffic in encapsulation format. Enabling this setting ensures that multicast and unknown unicast traffic is flooded in encapsulated format, which reduces the chance of loops and instability during the migration.
Therefore, the correct answer in this scenario is C. Set Multi-Destination Flooding to Flood in Encapsulation. It is worth noting that Endpoint Dataplane Learning should not be disabled as it is a critical component of the ACI fabric's functionality.
