Which two actions does the Cisco ACI take when a bridge domain is configured with a subnet and unicast routing is enabled? (Choose two.)

The correct answer is A. enables routing to and from that subnet C. learns MAC and IP addresses. Unicast Routing: If this setting is enabled and a subnet address is configured, the fabric provides the default gateway function and routes the traffic. Enabling unicast routing also instructs the mapping database to learn the endpoint IP-to-VTEP mapping for this bridge domain. T

Explanation

Unicast Routing: If this setting is enabled and a subnet address is configured, the fabric provides the default gateway function and routes the traffic. Enabling unicast routing also instructs the mapping database to learn the endpoint IP-to-VTEP mapping for this bridge domain. The IP learning is not dependent upon having a subnet configured under the bridge domain. x/L3_config/b_Cisco_APIC_Layer_3_Configuration_Guide/b_Cisco_APIC_Layer_3_Configuratio n_Guide_chapter_010.html
