DEA-C01 Data Store Management Practice Question
Network Topology
A data engineer is reviewing the lifecycle configuration of an S3 bucket. The bucket stores log files. The engineer wants to ensure that objects are deleted after 365 days. What is the current behavior?
⚠ Common exam trap
Watch out — candidates often confuse expiration (deletion) with transition (moving to another storage class), or assume that a lifecycle rule for current versions automatically applies to noncurrent versions, which is not the case without explicit NoncurrentVersionExpiration configuration.
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
✓
Objects are deleted after 365 days.
The lifecycle configuration is set to expire objects after 365 days, which means the S3 service will automatically delete the objects once they reach that age. Since the question states the engineer wants to ensure deletion after 365 days and the current behavior matches that, option A is correct. No transition actions are defined, so objects remain in the original storage class until expiration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Objects are deleted after 365 days.
Why this is correct
The expiration rule sets deletion after 365 days.
- ✗
Objects are transitioned to S3 Standard-IA immediately.
Why it's wrong here
Transition occurs after 30 days.
- ✗
Objects are transitioned to S3 Glacier after 365 days.
Why it's wrong here
No transition to Glacier is configured.
- ✗
Noncurrent versions of objects are deleted after 365 days.
Why it's wrong here
NoncurrentVersionExpiration is not configured.

| 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 |
