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.
