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

 To allow multiple external networks to communicate with internal ACI subnets and assign the prefix to the class ID of the external Endpoint Group, the engineer should configure subnets with the External Subnets for External EPG flag enabled1. This configuration allows the specified subnets to be associated with an external EPG, which facilitates communication between internal tenants and external routed networks via L3Outs1.

To meet the requirement of sending all faults and events related to endpoint groups, bridge domains, and VRFs to the new SNMP configuration and syslog servers, the network engineer should utilize common tenant monitoring policies in the Cisco APIC. The common tenant is used for global configurations that apply across the entire fabric, including monitoring policies.

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.
