D. proxy ARP. Disabling that will keep your network from turning into a hot mess when the default gateway is outside the bridge domain.

A. unknown unicast flooding. Seems like the logical choice to me, unless you want to flood your network with unnecessary traffic.

C. unicast routing. Clearly, the ACI bridge domain SVI isn't needed if the default gateway is external.

I'd go with D. Proxy ARP. Why would you want that if the default gateway is outside the bridge domain?

I believe unicast routing should also be disabled to ensure the endpoints use the external device as the default gateway.

I agree with you, Daniel. ARP flooding should be disabled because the default gateway is on an external device.
