What are two of the three methods in integrating the Cisco ACI with existing network infrastructure? (Choose two.)

The concept of 'super cloud overseeing a subcloud' is not a standard or recognized method for integrating Cisco ACI with existing network infrastructure.

Integrating ACI as a data center policy engine means ACI manages and enforces policies within its own domain, exchanging routing information with the existing network at the borders. This allows ACI to independently control its internal network services while coexisting with the broader infrastructure.

Cisco ACI is a comprehensive network fabric and policy management system, not merely a 'network supervisor module' for integration purposes.

Integrating ACI as an additional data center pod involves connecting ACI's border leaf switches to the existing network's core switches, extending the ACI fabric as a new, contiguous segment of the larger network. This approach allows the existing network to leverage ACI's policy-driven automation and benefits within the new pod.

'Atomic network operator' is not a standard term or integration method used to describe how Cisco ACI integrates with existing network infrastructure.
