The answer is AWS Lambda and Amazon Kinesis Data Firehose. Both services can ingest Kinesis Data Streams to S3 with partitioning by date while requiring minimal coding, because they natively support transforming and routing streaming records. Lambda acts as a lightweight processor that you can trigger from the stream, writing records directly to S3 with custom partition keys like year/month/day, while Firehose offers a fully managed delivery stream that automatically buffers, transforms, and partitions data into S3 with built-in dynamic partitioning. On the AWS Certified Data Engineer Associate DEA-C01 exam, this scenario tests your understanding of serverless ingestion patterns and the trade-off between control (Lambda) and simplicity (Firehose). A common trap is choosing Amazon Kinesis Data Analytics, which is for real-time analytics, not direct S3 delivery. For the memory tip: think “Lambda for logic, Firehose for fire-and-forget” — both let you partition by date without managing servers.
DEA-C01 Data Ingestion and Transformation Practice Question
This DEA-C01 practice question tests your understanding of data ingestion and transformation. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 streaming data from an existing Amazon Kinesis Data Streams into Amazon S3 with partitioning by date. Which TWO services can accomplish this with minimal coding? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon Kinesis Data Firehose
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Amazon Kinesis Data Firehose
Why this is correct
Firehose can read from a Kinesis stream and deliver to S3 with partitioning.

✗
AWS Glue Streaming
Why it's wrong here
Glue Streaming can process but requires more setup than Firehose or Lambda.
✓
AWS Lambda
Why this is correct
Lambda can be triggered by Kinesis records and write to S3 with custom partitioning.

✗
Amazon Kinesis Data Analytics
Why it's wrong here
Kinesis Data Analytics is for SQL or Flink processing, not direct S3 delivery.
✗
Amazon S3 Transfer Acceleration
Why it's wrong here
Transfer Acceleration is for uploading to S3, not consuming from Kinesis.
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.

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.
