Question 350
The source emits explicit delete events and the target must stop exposing removed customer records. Which postchange result provides the strongest validation of success?
Explanation
Correct Answer
The absence of a deleted key verifies CDC semantics. This observation directly tests the expected outcome.
Incorrect Answers
Single-row current-state validation proves an overwrite rather than a history append.
Point-in-time joins verify that history was preserved.
Matched row identity and updated values prove correct upsert behavior.
