300-620 Exam Dumps - Implementing Cisco Application Centric Infrastructure (300-620 DCACI)

 To export all configuration parameters necessary for disaster recovery in Cisco ACI, the setting that must be enabled is enabled JSON format export1. This format allows for a complete and structured export of the configuration that can be used for recovery purposes1.

To enable communication between EPGs and BDs from any tenant without the need for contracts or VRF route leaking, the best approach is to implement an unenforced VRF within the common tenant. By doing so, all bridge domains that are associated with this VRF will be able to communicate with each other without additional configurations. This method simplifies the network architecture and reduces the complexity associated with contract management and VRF route leaking1.

To ensure authentication if the RADIUS servers are unavailable, the action that should be taken is to set the fallback login to local. This setting allows users to authenticate using the local database on the Cisco APIC when external RADIUS servers cannot be reached.

To enable the APIC in a Cisco ACI fabric using out-of-band management connectivity to access a routable host with an IP address of 192.168.11.2, you need to add a Fabric Access Policy that allows management connections. This involves configuring a contract that will be consumed and provided to your OOB devices. The contract will let the system know what traffic is allowed. In this case, you will use the default/common contract to permit any traffic. This is necessary because the APIC needs to be able to send traffic to and receive traffic from the management network1.

To extend functional VMM integration to the new group of 70 bare-metal ESXi servers, a separate VMM domain should be implemented using the AEP_VMM. This allows for the management and automation of network policies for the bare-metal servers in a manner similar to the virtualized environment managed by vCenter1.

To clear the fault raised by the Cisco APIC when the EPG must accept endpoints from a VMM domain, the EPG should be associated with the VMM domain. This association is necessary for the APIC to recognize the endpoints within the VMM domain as part of the EPG. Without this association, the APIC cannot apply the policies defined in the EPG to the endpoints, which can result in errors1.
