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

In Cisco ACI, Virtual Routing and Forwarding (VRF) instances are used to create separate routing tables for network traffic management. An unenforced VRF does not apply policies or contracts for communication between endpoints, allowing free communication without the need for explicit permissions. By implementing an unenforced VRF in the common tenant and mapping all required Bridge Domains (BDs) to it, each department’s BDs can communicate with one another without configuring contracts or VRF route leaking, thus meeting the company’s requirement for redesigning their networking architecture. References: Implementing Cisco Application Centric Infrastructure Official Cert Guide

 To establish intra-VRF communication between two EPGs deployed across different sites with different bridge domains, stretching the bridge domain and EPG components is necessary. Option D, “bridge domain,” and Option E, “EPG,” must be configured as stretched to facilitate communication across different sites within the same VRF. References:= Implementing Cisco Application Centric Infrastructure Official Cert Guide

Enabling ARP flooding is necessary when VMs are migrated from a pre-existing network to Cisco ACI and their gateways remain in the legacy setup. This allows the ACI fabric to learn about silent hosts that do not initiate communication, ensuring that the migrated VMs can communicate with all hosts in the network, including those that are silent.
