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

In a Cisco ACI Multi-Pod deployment, the spine switches within a pod should not be directly connected to the spine switches in another pod. Instead, they should be connected to an IPN (Inter-Pod Network) device that provides Layer 3 IP connectivity between the pods. This setup allows for the extension of the ACI fabric across multiple locations while maintaining a single logical fabric. The IPN device can be a router or a switch with Layer 3 capabilities that can handle the necessary routing protocols and encapsulation methods required for Multi-Pod communication. References := Implementing Cisco Application Centric Infrastructure Official Cert Guide

To enable SSH communication between Web_EPG (Web Endpoint Group) and App_EPG (Application Endpoint Group), it’s necessary to apply a configuration that allows bidirectional communication while not restricting ports based on their directionality. By enabling “Apply Both Directions” and disabling “Reverse Filter Ports,” this ensures that the filter allows SSH packets to flow from Web_EPG to App_EPG and vice versa without any restrictions based on the port’s direction, which is essential for establishing an SSH session. References := ( Implementing Cisco Application Centric Infrastructure Official Cert Guide )

To allow reachability to services outside of the Cisco ACI fabric while conserving TCAM resources, an engineer should use a contract insertion method where L30ut external EPGsact as providers and vzAny inside VRF acts as consumers. This configuration allows for communication from all EPGs within a VRF (represented by vzAny) to access external services through L30ut without having to create individual contracts for each service EPG, thus saving TCAM resources. References: Implementing Cisco Application Centric Infrastructure Official Cert Guide
