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

 In a Cisco ACI Multi-Site setup, the ISN (Inter-Site Network) connects different ACI sites. For efficient multicast traffic routing, BIDIR-PIM (Bidirectional Protocol Independent Multicast) is configured throughout the ISN, which is why option B is correct. Increasing the ISN MTU (Maximum Transmission Unit) to support the maximum MTU sent by endpoints is crucial to prevent packet fragmentation or loss, making option C correct.

Options A, D, and E are not typically required for an ACI Multi-Site setup. Direct connectivity between Spine switches and ISN routers, as mentioned in options A and D, is usually established through leaf switches. Option E, enabling IGMPv3 on ISN routers, is more relevant for managing multicast subscriptions within a single site.
