The correct answer is A. Enable ARP Flooding. D. Set L2 Unknown Unicast Flood. Enable ARP flooding: ARP requests originated from devices connected to the Cisco ACI fabric should be able to reach the default gateway or other endpoints part of the same IP subnet and still connected to the brownfield network.

Question
Refer to the exhibit. An engineer must migrate workloads from the brownfield network to the Cisco ACI fabric. The VLAN 10 default gateway remains in the router located in the brownfield network. The bridge domain has already been associated with L2Out. Which two actions must be taken to migrate the workloads? (Choose two.)
Exhibit
Options
- AEnable ARP Flooding.
- BConfigure Multi-Destination Flooding Flood in Encapsulation.
- CSelect limit IP learning to Subnet.
- DSet L2 Unknown Unicast Flood.
- EMap the MAC address of the default gateway to the bridge domain.

Explanation
Enable ARP flooding: ARP requests originated from devices connected to the Cisco ACI fabric should be able to reach the default gateway or other endpoints part of the same IP subnet and still connected to the brownfield network. Since those entities are unknown to the Cisco ACI fabric, it is required to flood ARP requests across the Cisco ACI fabric and toward the brownfield Enable Unknown Unicast flooding: similar considerations valid for ARP traffic apply also to Layer 2 unknown traffic (unicast and multicast), so it is required to ensure flooding is enabled in this phase for those traffic types. g_existing_networks_to_aci.html#_Toc133408118
