DEA-C01 Data Ingestion and Transformation Practice Question
A data engineer is designing a data ingestion pipeline for real-time clickstream data from a website. The data must be ingested with low latency (seconds) and made available for multiple consumer applications, including a dashboard that refreshes every minute and a machine learning model that processes data in near-real-time. The engineer needs to choose a streaming ingestion service. Which TWO services meet these requirements? (Select TWO.)
⚠ Common exam trap
Many exam-takers confuse Amazon Kinesis Data Firehose with Kinesis Data Streams, assuming Firehose provides real-time ingestion, but Firehose buffers data for at least 60 seconds before delivery, making it unsuitable for sub-second latency requirements.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon Managed Streaming for Apache Kafka (Amazon MSK)
Amazon Kinesis Data Streams (C) provides sub-second ingestion latency and supports multiple consumer applications via its enhanced fan-out feature, enabling a dashboard and ML model to consume data concurrently with low latency. Amazon MSK (B) offers similar real-time capabilities with Apache Kafka's native pub/sub model, allowing multiple consumers to process the same stream independently and with low latency, meeting the near-real-time requirements.
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 it's wrong here
Firehose is for delivering data to destinations, not for multiple consumers; it buffers data.
- ✓
Amazon Managed Streaming for Apache Kafka (Amazon MSK)
Why this is correct
MSK is a fully managed Kafka service that provides low-latency streaming and supports multiple consumer groups.
- ✓
Amazon Kinesis Data Streams
Why this is correct
Kinesis Data Streams provides low-latency ingestion and supports multiple consumers via enhanced fan-out.
- ✗
Amazon Simple Queue Service (SQS)
Why it's wrong here
SQS is a queue, not a streaming platform; it doesn't support multiple independent consumers efficiently.
- ✗
Amazon S3
Why it's wrong here
S3 is object storage, not a streaming ingestion service.
