Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Lambda
AWS Lambda can be used to process deletion requests and trigger actions. Amazon S3 Batch Operations can perform bulk actions on S3 objects, such as deleting them. Amazon S3 Select can query specific records within S3 objects to identify which ones need deletion, enabling targeted removal. Together, these services automate the deletion of specific records to comply with GDPR. AWS Glue is an ETL service, not designed for selective deletion, and Amazon DynamoDB is a NoSQL database, not directly applicable to S3 data.
