DEA-C01Domain 4: Data Security and GovernanceData GovernancemediumSingle choice

A pipeline occasionally ingests files with nulls and schema drift, silently corrupting dashboards. What AWS capability evaluates data quality rules and can stop or alert on bad batches?

A.AWS Glue Data Quality

Correct. Purpose-built data quality rules and scoring.

B.S3 storage class analysis

Storage class analysis is about cost, not content quality.

C.CloudWatch billing alarms

Billing alarms watch spend, not data.

D.IAM Access Analyzer

Access Analyzer reviews permissions, not data quality.

Why this answer

AWS Glue Data Quality lets you define rules (completeness, uniqueness, schema conformance) evaluated against datasets — with results published to CloudWatch and the ability to fail jobs on rule violations.
