An engineer is extending an EPG out of the ACI fabric using static path binding. Which statement about the endpoints is true?

Extending an Endpoint Group (EPG) out of the ACI fabric using static path binding involves statically mapping a leaf port and a specific VLAN to an existing EPG. This configuration places the external endpoints connected via that path into the exact same EPG as the endpoints that are directly attached or dynamically learned within the fabric. Consequently, both external and internal endpoints share the same policy, bridge domain, and subnet configurations.

A. Endpoints must connect directly to the ACI leaf port: External endpoints can connect via an intermediate Layer 2 switch; they do not need to be directly attached to the ACI leaf port.

B. External endpoints are in a different bridge domain than the endpoints in the fabric: Because they are mapped to the same EPG, they are inherently tied to the same bridge domain as the internal endpoints.

C. Endpoint learning encompasses the MAC address only: ACI learns both MAC and IP addresses for endpoints in an EPG, including those connected via static path bindings.
