Selected Answer: D
El error HTTP 504 ocurre porque API Gateway tiene un tiempo de espera de integración que es menor que el tiempo total de ejecución (hasta 10 minutos). Refactorizando la función para iniciar un Step Functions state machine, se separa el procesamiento largo de la respuesta síncrona, evitando que API Gateway agote el tiempo de espera.
