Question 440
An engineering pipeline publishes trusted data from a third-party SaaS API. The current environment exhibits the following problem: the vendor adds an optional nested field that crashes strict mapping. Which corrective action addresses the root cause?
Explanation
Correct Answer
Implement validated schema-drift handling with default or quarantine policies. Schema evolution should not silently corrupt accepted data.
Incorrect Answers
The REST API is paginated but the load retrieves only its first page. Complete extraction requires following all source pages.
Authentication tokens expire in the middle of a large extraction. Long-running data movement needs renewable credentials.
The source returns the same page twice after an intermittent timeout. Page retrials must not inflate target rows.
