DEA-C01 Data Ingestion and Transformation Practice Question
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 is streaming clickstream data from a website into Amazon Kinesis Data Streams. The data must be transformed in near real-time and stored in Amazon S3 for analytics. Which AWS service should be used to transform the data as it is ingested?
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 Analytics
Option B is correct because Amazon Kinesis Data Analytics can process and transform streaming data in real-time using SQL or Apache Flink. Option A (AWS Glue) is a batch ETL service, not for real-time streams. Option C (Amazon EMR) is for big data processing but requires more setup. Option D (AWS Lambda) can process Kinesis records but is less efficient for complex transformations on high-throughput streams.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
AWS Lambda (streaming function)
Why it's wrong here
AWS Lambda can process Kinesis records but is not ideal for high-throughput or complex transformations.
✗
Amazon EMR (Spark Streaming)
Why it's wrong here
Amazon EMR can handle streaming but is more complex and overkill for simple transformations.
✗
AWS Glue (ETL jobs)
Why it's wrong here
AWS Glue is primarily a batch ETL service, not designed for real-time stream processing.
✓
Amazon Kinesis Data Analytics
Why this is correct
Amazon Kinesis Data Analytics can process and transform streaming data in real-time using SQL or Apache Flink.

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.
