A developer builds an online survey that requires all questions to have an answer.

This question pertains to theData Governancedomain, focusing on data quality and consistency in survey design. Requiring all questions to have an answer ensures a specific type of data quality.

Missing values (Option A): Requiring answers prevents missing values (NULLs or blanks) in the survey responses, which is the primary inconsistency this setting addresses.

Duplication (Option B): Duplication refers to repeated records, not prevented by requiring answers.

Data corruption (Option C): Data corruption involves damaged or altered data, not related to missing answers.

Completeness (Option D): Completeness is the concept of having all necessary data, but "missing values" is the specific inconsistency prevented here.

The DA0-002 Data Governance domain includes "data quality control concepts," and preventing missing values ensures data integrity in survey responses.
