A Cisco ACI fabric must detect all silent endpoints for the Layer 3 bridge domain. Which actions accomplish this goal?

The correct answer is A. Enable Unicast Routing.. A silent host in Cisco ACI is an endpoint that does not actively send traffic (like ARP requests) but still needs to be detected by the fabric. Cisco ACI can detect silent endpoints using data plane learning when routing is enabled. - Enable Unicast Routing: This allows ACI to le

Explanation

A silent host in Cisco ACI is an endpoint that does not actively send traffic (like ARP requests) but still needs to be detected by the fabric. Cisco ACI can detect silent endpoints using data plane learning when routing is enabled. - Enable Unicast Routing: This allows ACI to learn endpoints through Layer 3 mechanisms such as ARP Gleaning and routing lookups. If Unicast Routing is enabled, the fabric can track and detect silent hosts based on ARP requests - Disable ARP Flooding: Disabling ARP flooding ensures that ARP requests are handled in a more controlled way using the ARP Gleaning mechanism rather than being flooded across the fabric. This allows ACI to learn about silent hosts without requiring them to send out ARP requests.
