DEA-C01 Data Ingestion and Transformation Practice Question
A healthcare company processes patient records in near-real-time using Amazon Kinesis Data Streams. Each record contains sensitive personal health information (PHI). The data must be encrypted at rest and in transit. The company also needs to audit access to the data. The data engineer is designing the ingestion pipeline. Which combination of services and configurations meets these 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
✓
Use Kinesis Data Streams with SSE-KMS and TLS, and enable CloudTrail for data events.
Kinesis Data Streams supports server-side encryption (SSE) using AWS KMS for at-rest encryption, and TLS for in-transit. CloudTrail can log Kinesis API calls for auditing. Option A lacks encryption at rest. Option B lacks auditing. Option D is wrong because S3 does not replace Kinesis for streaming.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use Kinesis Data Firehose to deliver data to S3 with SSE-S3, and enable CloudTrail for S3.
Why it's wrong here
This is a different architecture; the question specifies near-real-time streaming, and Firehose is not a replacement for Kinesis Data Streams.
- ✗
Use Kinesis Data Streams with TLS and enable CloudTrail for auditing. Do not enable SSE.
Why it's wrong here
No at-rest encryption, which is required for PHI.
- ✓
Use Kinesis Data Streams with SSE-KMS and TLS, and enable CloudTrail for data events.
Why this is correct
Provides encryption at rest and in transit, plus auditing.
- ✗
Use Kinesis Data Streams with SSE-KMS and TLS. Do not enable any auditing.
Why it's wrong here
Lacks auditing capabilities.
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 |
