Which feature is used to propagate ARP, broadcast, and link-local frames across a Cisco SD-Access fabric to address connectivity needs for silent hosts that require reception of traffic to start communicating?
In Cisco SD-Access, Layer 2 flooding refers to the process of forwarding broadcast, unknown unicast, and multicast (BUM) traffic within a fabric to ensure connectivity for services that rely on Layer 2 communication. Cisco SD-Access uses a virtualized Layer 2 overlay network to provide Layer 2 connectivity while maintaining the scalability and segmentation benefits of the fabric.
Given answer is correct, this is also a good reference,

Native Fabric Multicast is the feature used to propagate ARP, broadcast, and link-local frames across a Cisco SD-Access fabric to address connectivity needs for silent hosts. It ensures that these types of frames are distributed to all the necessary endpoints in the fabric, including the silent hosts, allowing them to receive the required traffic and initiate communication.
