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

Removing pre-existing Fibre Channel over Ethernet (FCoE) configurations from Nexus devices is necessary to ensure compatibility with Cisco ACI mode. FCoE configurations are not supported in ACI mode, and their presence can hinder the migration process2.

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 )

The minimum MTU value that must be supported by the ISN to allow control plane endpoint information exchange between sites in a Cisco ACI Multi-Site setup with default settings is 1554 bytes (B). This accounts for the standard MTU of 1500 bytes plus additional overhead for VXLAN encapsulation. An MTU of 9000 (A) or 9100 © is not the minimum required, and 1600 (D) is not related to the default fabric settings5. References := (Multi-site / Multi-Pod MTU Jumbo Frames5)
