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

When configuring in-band management IP addresses for Cisco APICs, leaf nodes, and spine nodes, the tenant used is the mgmt tenant1.

 In a Cisco ACI Multi-Site fabric, when the Inter-Site BUM Traffic Allow option is enabled for a stretched bridge domain, ingress replication on the spines in the source site is used to forward Broadcast, Unknown unicast, and Multicast (BUM) traffic to all endpoints in the same broadcast domain. This method ensures that BUM traffic is replicated and sent out through the spines to the destination sites.

Enabling the “disable Remote EP learn” feature in Cisco ACI has the effect of preventing border leaf switches from receiving routes through peering with external routers. This feature is particularly useful when there is a mix of Gen1 and Gen2 hardware in the fabric, as it clears all the remote endpoints from the border leaf only. Traffic will still use hardware proxy if the endpoint is not learned on the border leaf, ensuring no operational impact12.
