The correct answer is B. Unicast Routing: Enabled. When you extend an existing L3-switched network into ACI and keep the original SVI as the gateway, enabling Unicast Routing on the bridge domain lets the fabric advertise its host routes back to that SVI. Setting L2 Unknown Unicast to HW Proxy ensures the spine/leaf fabric will…

Explanation
When you extend an existing L3-switched network into ACI and keep the original SVI as the gateway, enabling Unicast Routing on the bridge domain lets the fabric advertise its host routes back to that SVI. Setting L2 Unknown Unicast to HW Proxy ensures the spine/leaf fabric will proxy ARP and unknown-unicast MAC requests for those migrated servers so that “silent” hosts are reachable without flooding.
