300-630 Exam Dumps : Implementing Cisco Application Centric Infrastructure - Advanced (DCACIA)

An application-centric design in Cisco ACI focuses on the application requirements and interactions between different application components. In this design, EPGs (Endpoint Groups) represent different application tiers, such as web, application, and database tiers. This approach allows for a more flexible and scalable network configuration that aligns with the application architecture, enabling policies to be applied based on the application’s needs rather than the network topology. References := Implementing Cisco Application Centric Infrastructure Official Cert Guide

When traffic to certain endpoints is dropped in a Cisco ACI fabric configured with hardware proxy, setting the L2 Unknown Unicast option to Flood for Layer 2 switched traffic can prevent this problem. This mode allows unknown unicast traffic to be flooded within the bridge domain, rather than being sent to the spine proxy and potentially discarded if the destination is unknown5.

 For the ISN implementation between Cisco ACI data centers using Multi-Site, OSPF must be configured on subinterfaces for dynamic routing, and BIDIR-PIM must be set up on all ISN routers for efficient bidirectional multicast traffic routing. References := (Implementing Cisco Application Centric Infrastructure Official Cert Guide)
