}An S3 bucket is created using the above CloudFormation template. What happens to objects in the bucket after 30 days?
⚠ Common exam trap
Many exam-takers confuse expiration (deletion) with transition (moving to another storage class) and may incorrectly assume a prefix is mandatory for lifecycle rules to apply.
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 permanently deleted
The CloudFormation template defines a lifecycle rule with an expiration action that deletes objects after 30 days. Since no prefix is specified, the rule applies to all objects in the bucket. After 30 days, objects are permanently deleted, not transitioned to another storage class.
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 transitioned to Glacier
Why it's wrong here
No transition action is defined.
- ✗
The lifecycle rule is not applied because no prefix is specified
Why it's wrong here
The rule applies to the entire bucket.
- ✗
Objects are archived to S3 Standard-IA
Why it's wrong here
Expiration deletes, not archives.
- ✓
Objects are permanently deleted
Why this is correct
ExpirationInDays causes deletion after 30 days.

| 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 |
