CCAO-F Using the Claude API Practice Question
A developer is integrating the Claude API into a production pipeline and needs to handle a response where the model stopped because it hit the output token ceiling before finishing its answer. Which TWO actions are appropriate? (Choose two.)
⚠ Common exam trap
The trap here is treating a 200 response as proof of completeness, when stop_reason is what actually signals whether output was truncated.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Inspect the 'stop_reason' field and treat a value indicating the token limit as a truncation signal.
When generation stops because it reached the output token ceiling, the response still returns successfully but the content is incomplete. The application should detect this via stop_reason and then either allow more output tokens or continue from the partial text. Retrying unchanged, adjusting temperature, or trusting the HTTP status all fail to detect or resolve the truncation.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Assume the response is complete and parse it as-is, since a 200 status was returned.
Why it's wrong here
A successful HTTP status only means the request was processed, not that the answer is whole. When the output ceiling is reached, the API still returns 200 with partial content, so parsing it as complete would silently propagate a truncated result through the production pipeline.
- ✓
Inspect the 'stop_reason' field and treat a value indicating the token limit as a truncation signal.
Why this is correct
The response's stop_reason tells the application why generation ended. A value indicating the output token limit means the answer was cut off, so checking this field lets the pipeline detect truncation programmatically and decide how to respond, rather than silently consuming an incomplete result.
- ✗
Retry the identical request unchanged, expecting the model to finish within the same limit.
Why it's wrong here
Reissuing the same prompt with the same max_tokens will hit the same ceiling again, because nothing about the budget or the input changed. Retrying unchanged wastes tokens and latency without producing a complete answer, so it does not address the truncation in this pipeline.
- ✗
Lower 'temperature' to 0 so the model produces a shorter answer next time.
Why it's wrong here
Temperature affects randomness, not length. Setting it to zero makes sampling deterministic but does not shorten output, so the model could still run to the same token ceiling. It is therefore not a remedy for a response truncated by the output limit in this pipeline.
- ✓
Raise 'max_tokens' or continue the response by sending the partial output back as an assistant turn.
Why this is correct
Truncation caused by the output ceiling is resolved by giving the model more room. Increasing max_tokens on a fresh call, or continuing from the partial text by placing it in an assistant turn and prompting for completion, both let the model finish the answer that was previously cut off.
