When an engineer extends an End Point Group (EPG) outside of the Application Centric Infrastructure (ACI) fabric using static path binding, the following statement is true:

D. External endpoints are in the same EPG as the directly attached endpoints.

Explanation:

An EPG represents a group of endpoints that share common network policies, and these endpoints are located either within the ACI fabric or outside of it. When an EPG is extended outside of the ACI fabric using static path binding, it allows communication between the endpoints inside the ACI fabric and those outside of it. Static path binding is a method of defining a specific path between an endpoint and an external device, such as a switch, router, or firewall.

When an EPG is extended using static path binding, the external endpoints are part of the same EPG as the endpoints directly attached to the ACI leaf port. This means that both the endpoints inside the ACI fabric and those outside of it are part of the same EPG and share the same network policies. The advantage of this approach is that it simplifies policy enforcement, as the same policies can be applied to all the endpoints in the EPG regardless of their location.

Endpoint learning encompasses not only the MAC address but also the IP address and other attributes of the endpoint, such as the VLAN, the port, and the application. Therefore, it is important to ensure that the network policies applied to the EPG are consistent and appropriate for all the endpoints in the group.

To summarize, when extending an EPG outside of the ACI fabric using static path binding, the external endpoints are in the same EPG as the endpoints directly attached to the ACI leaf port, and endpoint learning encompasses more than just the MAC address.
