Question 100 of 1,711
DEA-C01 Data Store Management Practice Question
A data engineer is designing a data lake on Amazon S3. The data must be immutable and support high-throughput streaming ingestion. Which THREE features should the engineer consider? (Select THREE.)
⚠ Common exam trap
Test-takers frequently confuse S3 Transfer Acceleration (a speed optimization) with a feature that provides immutability or streaming support, leading them to select it incorrectly, while overlooking that S3 Object Lock and Multipart Upload directly address the core requirements of immutability and high-throughput ingestion.
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
✓
S3 Lifecycle policies to transition data to Amazon S3 Glacier
S3 Object Lock in governance mode (Option D) is correct because it enforces immutability by preventing objects from being deleted or overwritten for a specified retention period, which is essential for a data lake requiring immutable data. S3 Multipart Upload API (Option C) is correct because it enables high-throughput streaming ingestion by allowing large objects to be uploaded in parallel parts, improving throughput and resilience. S3 Lifecycle policies to transition data to Amazon S3 Glacier (Option B) is correct because it supports cost-effective storage management for immutable data that is rarely accessed, aligning with the data lake's lifecycle needs.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
S3 Transfer Acceleration
Why it's wrong here
Transfer Acceleration speeds up uploads over long distances but does not provide immutability or streaming-specific benefits.
- ✓
S3 Lifecycle policies to transition data to Amazon S3 Glacier
Why this is correct
Lifecycle policies automate data movement, cost-effectively managing the data lifecycle.
- ✓
S3 Multipart Upload API
Why this is correct
Multipart Upload allows large objects to be uploaded in parts, improving throughput for streaming ingestion.
- ✓
S3 Object Lock in governance mode
Why this is correct
Object Lock prevents objects from being deleted or overwritten for a specified period, providing immutability.
- ✗
S3 Cross-Region Replication (CRR)
Why it's wrong here
CRR copies objects to another region for redundancy, but is not a core requirement for immutability or streaming ingestion.
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 |
