Amazon Kinesis Data Streams with a custom consumer application writing to S3
Why wrong: Requires managing consumers and scaling; higher operational overhead.
- B
Amazon Kinesis Data Firehose with S3 as the destination
Firehose automatically writes to S3 with near-real-time delivery and low overhead.
- C
AWS Glue ETL job running on a schedule to pull data from a message queue
Why wrong: Glue ETL is batch-oriented and not suited for sub-minute latency.
- D
AWS Database Migration Service (DMS) with S3 as target
Why wrong: DMS is for database migration, not streaming web data.

MLA-C01 Practice Question: A data engineer is ingesting streaming…
This MLA-C01 practice question tests your understanding of a data engineer is ingesting streaming…. 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 is ingesting streaming clickstream data from a website into Amazon S3 for ML training. The data arrives at a rate of 10,000 events per second, and the team needs near-real-time availability with minimal transformation. Which AWS service should the engineer use to ingest the data into S3 with the LEAST operational overhead?
Clue words in this question

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
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.
Quick reference
AWS S3 Storage Class Comparison
| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
