問題文

A downstream API answers a request with a status code that says the service is temporarily unavailable. What is the correct reaction inside the calling flow?

選択肢

1. Return the answer to the original caller because the code describes a fault the caller has to correct.
2. Wait a moment and send the same request again because the code describes a condition that clears with time.
3. Send the request to a different endpoint because the code describes a fault in the address that was used.
4. Map the answer to a business error because the code describes a fault in the request that was sent.
