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 data engineer needs to ingest data from an on-premises Oracle database into Amazon S3 for analytics. The data changes frequently and the engineer wants to capture both initial load and incremental changes with minimal latency. Which TWO AWS services should be used together? (Choose TWO.)
AWS Database Migration Service (DMS)
DMS can perform ongoing replication from Oracle to S3.
AWS Lambda
Why wrong: Lambda can process events but not directly replicate databases.
AWS Glue
Why wrong: Glue is for ETL jobs, not real-time replication.
AWS Transfer Family
Why wrong: Used for SFTP/FTPS transfers, not database replication.
Amazon Kinesis Data Streams
Kinesis can stream change data captured by DMS to S3.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
AWS Database Migration Service (DMS)
Option B and Option D are correct. AWS DMS can continuously replicate changes from Oracle to S3, and Amazon Kinesis Data Streams can provide low-latency streaming for near-real-time data. Option A is for batch file transfer, not real-time. Option C is for ETL, not replication. Option E is for event-driven processing but not direct database replication.
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
For each option: why learners choose it and why it is or isn't the right answer here.
AWS Database Migration Service (DMS)
Why this is correct
DMS can perform ongoing replication from Oracle to S3.
Related concept
Standard ACLs match source addresses.
AWS Lambda
Why it's wrong here
Lambda can process events but not directly replicate databases.
AWS Glue
Why it's wrong here
Glue is for ETL jobs, not real-time replication.
AWS Transfer Family
Why it's wrong here
Used for SFTP/FTPS transfers, not database replication.
Amazon Kinesis Data Streams
Why this is correct
Kinesis can stream change data captured by DMS to S3.
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.
