Which of the following best describes an assessment a data analyst would use to validate that the number of records in a dataset matches the expected results?

Source control manages code versions and changes, not data validation.

A unit test specifically validates individual components or functions, and in a data context, this can include verifying that data operations, like record counts, produce expected outcomes. This helps ensure the accuracy and integrity of data processing steps.

A stress test evaluates system performance under extreme loads, not the accuracy of record counts.

A health check assesses the operational status of a system or service, not specific data validation logic.
