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

 In a Cisco ACI Multi-Pod environment that is expanding, spine headend replication should be configured to ensure efficient forwarding of BUM (Broadcast, Unknown unicast, Multicast) traffic across the IPN (Inter-Pod Network). This configuration optimizes the control plane scaling and ensures that BUM traffic is handled effectively, maintaining network performance and stability.

To ensure the Cisco ACI fabric adheres to strict security protocols and only learns endpoints from configured subnets on a bridge domain, the “Enforce Subnet Check” feature must be enabled. This feature restricts endpoint learning to IP addresses belonging to the subnets defined in the bridge domain associated with the endpoint’s VLAN, enhancing security by preventing learning of endpoints from unconfigured subnets. References: Implementing Cisco Application Centric Infrastructure Official Cert Guide

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
