Question
Refer to the exhibit. Server A is connected to the Cisco ACI fabric using two teamed interfaces. One interface in a team is configured as active and the other remains in standby mode. When a failover occurs and the standby interface becomes active, it uses its built-in MAC address to send traffic. Which bridge domain configuration must be applied to resolve the issue?
Exhibit
Options
- AConfigure Hardware proxy.
- BSet L2 Unknown Unicast to Flood.
- CEnable ARP flooding.
- DActivate Limit IP Learning to Subnet.

Explanation
In the scenario where Server A is connected to the Cisco ACI fabric using teamed interfaces with one active and one standby, enabling ARP flooding in the bridge domain configuration is necessary to resolve the issue that occurs when the standby interface becomes active and uses its built-in MAC address to send traffic. Enabling ARP flooding allows the fabric to learn the new MAC address without waiting for the ARP timeout, which helps to ensure that traffic continues to flow to the correct destination after a failover event.
