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 receives streaming clickstream data from its website. The data must be ingested with low latency and transformed in real time before being stored in Amazon S3. Which AWS service combination is most suitable for this use case?
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 Streams with Amazon Kinesis Data Analytics
Option B is correct because Amazon Kinesis Data Streams ingests streaming data with low latency, and Kinesis Data Analytics can perform real-time transformations using SQL or Apache Flink. Option A is wrong because Kinesis Data Firehose is a delivery service that can transform data but with higher latency. Option C is wrong because AWS Glue is a batch ETL service. Option D is wrong because Amazon S3 is a storage service, not for real-time transformation.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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 S3 with S3 Object Lambda
Why it's wrong here
S3 Object Lambda transforms data on retrieval, not for real-time ingestion.
✓
Amazon Kinesis Data Streams with Amazon Kinesis Data Analytics
Why this is correct
Kinesis Data Streams provides low-latency ingestion and Kinesis Data Analytics enables real-time transformations.
Related concept
Static NAT maps one inside address to one outside address.
✗
Amazon Kinesis Data Firehose with AWS Lambda for transformation
Why it's wrong here
Kinesis Data Firehose has higher latency and is not ideal for real-time transformations.
✗
AWS Glue jobs triggered by Amazon S3 events
Why it's wrong here
AWS Glue is a batch ETL service, not real-time.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related DEA-C01 NAT questions on configuration and troubleshooting.
Data Ingestion and Transformation — This question tests Data Ingestion and Transformation — Static NAT maps one inside address to one outside address..
What is the correct answer to this question?
The correct answer is: Amazon Kinesis Data Streams with Amazon Kinesis Data Analytics — Option B is correct because Amazon Kinesis Data Streams ingests streaming data with low latency, and Kinesis Data Analytics can perform real-time transformations using SQL or Apache Flink. Option A is wrong because Kinesis Data Firehose is a delivery service that can transform data but with higher latency. Option C is wrong because AWS Glue is a batch ETL service. Option D is wrong because Amazon S3 is a storage service, not for real-time transformation.
