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

 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)

When a host connected to a Cisco ACI fabric leaf switch sends an ARP request, the ingress leaf switch uses a broadcast transmission method to send the ARP requests. This is because ARP requests are meant to discover the MAC address associated with a specific IP address within the same network broadcast domain. The ingress leaf switch does not know the destination MAC address, so it broadcasts the ARP request to all devices within the broadcast domain1.
