Question 1,471 of 1,616
S3 Lifecycle Rules: Transition to Glacier and Delete
This DVA-C02 practice question tests your understanding of development with aws services. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A developer wants to store application logs in Amazon S3 with automatic transition to Glacier after 30 days and deletion after 365 days. Which S3 feature should be used?
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 configuration
S3 Lifecycle configuration is the correct feature because it allows you to define rules that automatically transition objects to colder storage classes like Glacier after a specified number of days (30) and permanently delete them after a longer period (365). This directly matches the requirement for time-based storage tiering and deletion without manual intervention.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
S3 Object Lock
Why it's wrong here
Object Lock prevents deletion, not transitions.
- ✗
S3 Replication
Why it's wrong here
Replication copies objects to another bucket.
- ✗
S3 Event Notifications
Why it's wrong here
Event notifications trigger on events but don't manage lifecycle.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse S3 Lifecycle policies with S3 Event Notifications, thinking event-driven triggers can handle time-based transitions, but Lifecycle policies are the only native S3 feature that automates storage class transitions and deletions based on object age.
Detailed technical explanation
How to think about this question
S3 Lifecycle policies are evaluated daily (once every 24 hours) by an asynchronous process, so transitions or deletions may not occur exactly at the 30th or 365th day but within 24 hours of that date. The policy uses XML-based rules with 'Expiration' and 'Transition' actions, where you specify the 'Days' parameter relative to object creation. A common real-world scenario is cost optimization for log data that must be retained for compliance but rarely accessed after the first month.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
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 |
