Data 360 Consultant Data Ingestion And Modeling Practice Question
A Data Cloud Consultant is setting up a batch data stream from an AWS S3 bucket to ingest daily transaction records. During the configuration, the consultant notices that the incoming CSV files contain columns with varying headers across different days. How should the consultant configure the data stream to ensure successful ingestion without breaking the mapping?
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
✓
Ensure that the source CSV files maintain a consistent header row matching the defined Data Source Object schema.
When configuring data streams from cloud storage like AWS S3, the underlying schema must align with the Data Source Object (DSO) definition. In Data Cloud, schema drift can cause ingestion errors, so establishing a strict contract or utilizing a consistent header structure in the source file, or leveraging standard connector parsing rules, is critical. Data Cloud does not automatically remap changing column names.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable dynamic schema evolution in the Data Stream properties.
Why it's wrong here
Data Cloud does not feature an automated dynamic schema evolution toggle for standard batch S3 data streams that remaps changing headers automatically.
- ✓
Ensure that the source CSV files maintain a consistent header row matching the defined Data Source Object schema.
Why this is correct
Data streams rely on the DSO schema matching the file structure; inconsistent headers will lead to ingestion failures or unmapped fields.
- ✗
Create multiple data streams, one for each variation of the CSV header.
Why it's wrong here
Creating multiple data streams is inefficient and does not solve the underlying upstream data governance issue.
- ✗
Map the S3 bucket directly to a Data Model Object using formula fields to handle missing headers.
Why it's wrong here
Data streams must first map to a Data Source Object before mapping to a Data Model Object.

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 |
