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 support an application that is sensitive to latency and jitter, it is crucial to ensure that the Quality of Service (QoS) levels within the ACI fabric and the Inter-Pod Network (IPN) QoS policies are aligned. This alignment will help in maintaining consistent handling of the DSCP values set by the application (AF31 and CS6) as the packets traverse across the two ACI pods. By aligning the QoS levels and policies, the application’s packets are less likely to experience delays or drops, thus preserving the required performance levels for the application’s optimal functionality.
