This DEA-C01 practice question tests your understanding of data ingestion and transformation. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company needs to ingest data from an on-premises Oracle database into Amazon S3 for analytics. The data volume is about 1 TB initially, with daily incremental updates of about 10 GB. Which TWO services can be combined to achieve this with minimal custom code?
AWS Glue
Why wrong: Can be used but DMS is simpler for this use case.
Amazon Kinesis Data Streams
Why wrong: Not designed for database migration.
Amazon Athena
Why wrong: Query service, not data ingestion.
Amazon S3
Target for the ingested data.
AWS Database Migration Service (DMS)
Handles full load and CDC from Oracle.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Amazon S3
Options A and D are correct because AWS DMS can perform full load and ongoing replication, and S3 is the target. Option B (Kinesis Data Streams) is for real-time streaming, not database migration. Option C (Glue) can be used but often requires more custom code than DMS. Option E (Athena) is a query service, not data movement.
Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Answer analysis

Standard ACLs match source addresses.
AWS Database Migration Service (DMS)
Why this is correct
Handles full load and CDC from Oracle.
Related concept
Standard ACLs match source addresses.
Common exam traps
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Detailed technical explanation
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
Key takeaway
ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Real-world example
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
What to study next
Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related DEA-C01 ACL questions on filtering logic and placement.
