- A
Enable MFA Delete on the bucket.
Why wrong: MFA Delete adds protection but doesn't enforce retention period.
- B
Configure an S3 Lifecycle policy to transition objects to Glacier after 7 years.
Why wrong: Lifecycle transitions objects, does not prevent deletion.
- C
Enable S3 Versioning to preserve all versions of objects.
Why wrong: Versioning preserves overwrites, not deletion.
- D
Create an S3 bucket policy that denies s3:DeleteObject unless the object age is greater than 7 years.
Denies deletion of objects younger than 7 years.

SCS-C02 S3 Object Lock Practice Question
This SCS-C02 practice question tests your understanding of infrastructure security. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. A key principle to apply: s3 Object Lock. 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 company wants to store audit logs for a minimum of 7 years to meet compliance requirements. The logs are stored in Amazon S3. Which action should be taken to ensure logs are not deleted before 7 years?

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
✓
Create an S3 bucket policy that denies s3:DeleteObject unless the object age is greater than 7 years.
While S3 bucket policies do not directly support denying deletion based on object age, the provided options must be evaluated. MFA Delete (A) only adds an authentication step, not a retention period. Lifecycle policies (B) only transition storage classes and do not prevent deletion. Versioning (C) preserves previous versions but not the current one. Therefore, option D is the best available choice, as it attempts to enforce a retention period via a policy, although in practice S3 Object Lock with Compliance mode would be the correct solution.

Key takeaway
S3 Object Lock
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.

| 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 |
