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

The configuration set that accomplishes the goals of allowing communication between the external subnet and internal EPG1, as well as leaking L30ut traffic into VRF named “VF1”, is option D: Export Route Control Subnet Import Route Control Subnet Aggregate Shared Routes. This configuration ensures that routes are properly exported from one entity and imported into another while aggregating shared routes for efficient routing within the VRF “VF1”. It allows for controlled route leaking which is necessary for communication across different entities within a Cisco ACI environment. References := ( Implementing Cisco Application Centric Infrastructure Official Cert Guide )

For shared L3Out network connectivity among different tenants in a Cisco ACI fabric, a common tenant is necessary. It provides a global space for defining resources like L3Outs once, which can then be utilized by multiple tenants, simplifying management and ensuring consistent policy application. 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
