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

 To configure a group of servers with a contract that uses TCP port 80 and requires an external Layer 3 cloud to initiate communication, the EPG that contains the web servers should be configured as a consumer of the contract, and the Layer 3 Out (L3Out) should be configured as the provider of the contract. This configuration establishes the direction of the contract and allows the external Layer 3 cloud to initiate communication with the web servers within the EPG.

 For Cisco ACI IPN (Inter-Pod Network) to manage multidestination traffic, multicast routing is a requirement. This is because multidestination traffic includes broadcast, unknown unicast, and multicast (BUM) traffic, which needs to be efficiently transported across different pods in a Cisco ACI Multi-Pod environment. Multicast routing protocols like Bidirectional Protocol-Independent Multicast (Bidir PIM) are used to handle this type of traffic1.

 In Cisco ACI, the object classes are used to categorize different types of managed objects within the ACI model. The output presented is indicative of a Tenant class object. Tenants in ACI are a top-level container for application policies, essentially providing a unit of isolation from other tenants. Each tenant can contain its own application policies, services, and network policies, and they are separate from other tenants to ensure multi-tenancy1.
