Correct answer & explanation
✓
A Service Attachment that exposes the service.
Private Service Connect allows producers to publish services via a Service Attachment. The service attachment is created on a Network Endpoint Group (NEG) that points to the internal service (e.g., a backend service). Consumers then create PSC endpoints to connect.
