Question 153
CCA-F is a newly released exam. These practice questions reflect our best current understanding — the exact wording and question formats may change in the live exam until the certification matures. Use them to learn the concepts, not to memorize.
Scenario: Structured Data Extraction - An extraction schema marks `middle_name` as required. Many source documents have no middle name, and the model fabricates plausible-looking values to satisfy the required field, polluting the dataset. How should the schema be designed?
- AKeep the field required but add "do not guess" to the prompt.
- BMake the field nullable (`"type": ["string", "null"]`) so the model can return null when the information is absent.
- CRemove the field from the schema entirely so nothing is reported.
- DSet a required default of "N/A" as a string.
