- A
Use SSE-KMS with a customer-managed key that has automatic key rotation enabled.
KMS CMK with automatic rotation meets the requirement.
- B
Use AWS CloudHSM to generate a key and encrypt data before uploading to Glacier.
Why wrong: Client-side encryption; CloudHSM does not provide automatic rotation.
- C
Use client-side encryption with the Amazon S3 encryption client.
Why wrong: Client-side encryption does not use S3's server-side encryption.
- D
Use SSE-C with keys stored in AWS Secrets Manager and rotate keys annually.
Why wrong: SSE-C requires manual rotation; Secrets Manager can help but not automatic.
- E
Use the default encryption provided by S3 Glacier (SSE-S3).
SSE-S3 uses Amazon-managed keys with annual rotation.

SCS-C02 Data Protection Practice Question
This SCS-C02 practice question tests your understanding of data protection. 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. 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 company wants to protect data stored in Amazon S3 Glacier. The data must be encrypted at rest and the encryption keys must be rotated annually. Which TWO options meet these requirements?
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 SSE-KMS with a customer-managed key that has automatic key rotation enabled.
Option A is correct because SSE-KMS with a customer-managed key that has automatic key rotation enabled allows annual rotation and meets the encryption requirement. Option E is correct because S3 Glacier's default encryption, SSE-S3, encrypts data at rest and AWS manages key rotation automatically on an annual basis. Option B is incorrect because AWS CloudHSM requires manual key rotation. Option C is incorrect because client-side encryption with the Amazon S3 encryption client does not use server-side encryption and requires manual key management. Option D is incorrect because SSE-C requires you to manage and rotate the keys manually.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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 |
