Selected Answer: D
The bridge domain setting used for a Cisco ACI leaf switch to learn the source IP address of a packet entering its front panel port is: Unicast routing enabled When unicast routing is enabled on the bridge domain, the ACI leaf switch can perform IP address learning from the data plane. This allows the leaf to learn both the MAC address and IP address of incoming packets on its front panel ports. If unicast routing is disabled on the bridge domain, the leaf switch will only learn MAC addresses and perform Layer 2 switching, without learning any IP addresses
