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

Enabling ARP flooding is necessary when VMs are migrated from a pre-existing network to Cisco ACI and their gateways remain in the legacy setup. This allows the ACI fabric to learn about silent hosts that do not initiate communication, ensuring that the migrated VMs can communicate with all hosts in the network, including those that are silent.

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 )
