DEA-C01 Data Store Management Practice Question
Network Topology
A data engineer runs the AWS CLI command shown in the exhibit to list objects in an S3 bucket. The command returns only two objects even though the bucket contains thousands of objects under the prefix. What should the engineer do to retrieve the next batch of objects?
⚠ Common exam trap
A common mix-up: candidates confuse `--page-size` (which controls API call size but not pagination) with `--starting-token` (which actually advances the pagination cursor), leading candidates to incorrectly choose option C.
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 the --starting-token parameter with the value from the NextToken field.
The AWS CLI `list-objects-v2` command paginates results by default. When the output is truncated, the response includes a `NextToken` field. To retrieve the next batch, the engineer must use the `--starting-token` parameter with the value from that `NextToken` field, which tells the CLI to resume listing from where it left off.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increase the --max-items value to a larger number.
Why it's wrong here
Increasing --max-items will retrieve more items in one page, but the command still returns only one page; it doesn't automatically fetch the next page.
- ✓
Use the --starting-token parameter with the value from the NextToken field.
Why this is correct
The NextToken is used with --starting-token to get the next page of results.
- ✗
Use the --page-size parameter to request more items per API call.
Why it's wrong here
--page-size controls the number of items fetched per underlying API call, but the CLI still returns a single page; it doesn't paginate automatically without --starting-token.
- ✗
Change the --prefix to a more specific value.
Why it's wrong here
Changing prefix would filter results, not paginate.

| 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 |
