- A
Amazon S3 server-side encryption
Why wrong: S3 SSE is for object storage, not directly for EBS volumes.
- B
Amazon EBS encryption
EBS volumes can be encrypted using KMS keys.
- C
AWS Key Management Service (KMS)
KMS allows you to create and manage customer managed keys with automatic annual rotation.
- D
AWS CloudHSM
CloudHSM provides dedicated HSM for key storage and can be used with KMS via custom key store.
- E
AWS Certificate Manager (ACM)
Why wrong: ACM manages SSL/TLS certificates, not encryption keys for data at rest.
Question 1,171 of 1,733
PAS-C01 Technology Practice Question
This PAS-C01 practice question tests your understanding of technology. 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.
An organization runs SAP on AWS and wants to encrypt all data at rest for the SAP HANA database. The encryption keys must be managed by the customer and rotated annually. Which THREE AWS services can be used together to meet these requirements? (Choose THREE.)
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
✓
Amazon EBS encryption
Amazon EBS encryption is correct because SAP HANA databases on AWS typically store data on EBS volumes, and enabling EBS encryption ensures data at rest is encrypted using AWS KMS keys. This directly meets the requirement for encrypting the SAP HANA database storage.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Amazon S3 server-side encryption
Why it's wrong here
S3 SSE is for object storage, not directly for EBS volumes.

AWS Certificate Manager (ACM)
Common exam traps
Common exam trap: answer the scenario, not the keyword
A common mistake is to confuse ACM (which handles certificates for encryption in transit) with services that handle encryption at rest (KMS, CloudHSM, EBS encryption). ACM does not provide encryption at rest and is not relevant for encrypting SAP HANA database storage.
Detailed technical explanation
How to think about this question
SAP HANA on AWS often uses EBS volumes for data and log storage; enabling EBS encryption with a customer-managed KMS key ensures AES-256 encryption at rest. AWS CloudHSM provides a dedicated hardware security module (HSM) that can be used as a key store for KMS via custom key stores, allowing the customer to manage and rotate keys annually while meeting compliance requirements like PCI DSS or FIPS 140-2 Level 3.
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 |
