- D. the parser
3. A successful JSON parse tells you…
- A. the values are usable
- B. only that the shape was JSON
- C. the model was confident
- D. the schema matched
4. A retry after a malformed response should include…
- A. the same prompt
- B. the specific error that occurred
- C. a higher temperature
- D. a different model
5. Widening an enum in a schema breaks…

Answer Key and Explanations
Check these only after attempting every question.
1. B - the model says 'invoicing' instead of 'billing'
Each of those is a normal thing for generated text to do, and the regex accumulates special cases.
2. B - max_tokens set too low
It presents as intermittent parse failure and has a completely different fix from a model problem.
3. B - only that the shape was JSON
A plausible label outside your allowed set parses perfectly and breaks the router.
4. B - the specific error that occurred
'Please try again' gives the model nothing it did not have, at full cost per attempt.
5. B - old code reading new data
Deploy readers first - during a rolling deploy both versions run at once.
Practical Check
Apply this module to your own work: complete the module activity for *Structured Outputs with Schemas*, then write one sentence naming what your result shows and one naming what it does not.
Strong Answer Pattern
A strong answer names the task, the evidence used, the check performed, and the remaining limitation. It avoids "proved", "guaranteed", or "always" unless the evidence genuinely supports it.
