300-620 Exam Dumps : Implementing Cisco Application Centric Infrastructure (300-620 DCACI)

To reduce instability during the migration of a legacy environment to Cisco ACI, the feature that should be enabled in the bridge domain is to Set Multi-Destination Flooding to Flood in BD (Option A). This setting allows unknown multicast, broadcast, and unknown unicast traffic to be flooded within the bridge domain, which can help prevent traffic loss during the migration process.

When configuring an L3Out in Cisco ACI and encountering a QoS-related error, creating a custom QoS policy is often necessary to clear the fault. This involves defining a QoS policy that meets the specific requirements of the L3Out configuration and applying it to the relevant interfaces or globally within the fabric. The custom QoS policy should be designed to prioritize traffic appropriately and ensure that the necessary QoS settings are in place for the L3Out connections1.
