This MLS-C01 practice question tests your understanding of data engineering. 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 team wants to move data from an on-premises Oracle database to Amazon S3 for analytics. The pipeline must run daily and handle incremental updates. Which THREE services should they use together? (Choose three.)
Amazon SageMaker
Why wrong: SageMaker is for building and training ML models, not for data ingestion.
Amazon S3
S3 is the target data lake storage.
Amazon Athena
Why wrong: Athena queries data but does not move it.
AWS Database Migration Service (DMS)
DMS supports ongoing replication from Oracle to S3.
AWS Glue
Glue can transform data after it lands in 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
Amazon S3
Options A, B, and D are correct. AWS DMS can do continuous replication from Oracle to S3. Glue can transform the data. S3 is the target. Option C is wrong because SageMaker is for ML, not data ingestion. Option E is wrong because Athena is a query engine, not a data movement service.
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.
Amazon SageMaker
Why it's wrong here
SageMaker is for building and training ML models, not for data ingestion.
Amazon S3
Why this is correct
S3 is the target data lake storage.

AWS Database Migration Service (DMS)
Why this is correct
DMS supports ongoing replication from Oracle to S3.
Related concept
Standard ACLs match source addresses.
AWS Glue
Why this is correct
Glue can transform data after it lands in 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 MLS-C01 ACL questions on filtering logic and placement.
