Refer to the exhibit. An engineer must configure a bridge domain inside the Cisco ACI fabric called BD. The configuration must permit EP2 and EP3 to reach EP1. Which configuration must be applied on…

The correct answer is B. Enable L2 Unknown unicast flooding. While enabling L2 Unknown Unicast flooding ensures that traffic is flooded to all ports when the destination MAC address is unknown, this does not directly achieve unicast routing between EPs. Unicast routing is more efficient for known unicast traffic.
