- A
Use client-side encryption before uploading to S3
Why wrong: Client-side encryption uses client-managed keys, not the same CMK.
- B
Configure the S3 bucket to use SSE-KMS with the same CMK
SSE-KMS allows specifying a particular CMK.
- C
Add a bucket policy that denies if encryption is not present
Why wrong: Policy can enforce encryption but does not specify the key.
- D
Enable default encryption on the S3 bucket with SSE-S3
Why wrong: SSE-S3 uses AWS-managed keys, not the same CMK.
Question 231 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.
A company is running SAP on AWS and wants to implement encryption at rest for all data. The company uses AWS KMS with Customer Managed Keys (CMKs) for the EBS volumes. The SAP application servers need to access an S3 bucket that contains sensitive data. How should the company ensure that the S3 bucket is encrypted with the same CMK?
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
✓
Configure the S3 bucket to use SSE-KMS with the same CMK
Option B is correct because SSE-KMS (Server-Side Encryption with AWS KMS) allows you to specify a Customer Managed Key (CMK) to encrypt objects in S3. By configuring the S3 bucket to use the same CMK that is already used for EBS volumes, the company ensures a unified encryption key strategy for all data at rest, meeting the requirement for consistent encryption across services.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use client-side encryption before uploading to S3
Why it's wrong here
Client-side encryption uses client-managed keys, not the same CMK.
- ✓
Configure the S3 bucket to use SSE-KMS with the same CMK
Why this is correct
SSE-KMS allows specifying a particular CMK.

- ✗
Add a bucket policy that denies if encryption is not present
Why it's wrong here
Policy can enforce encryption but does not specify the key.
- ✗
Enable default encryption on the S3 bucket with SSE-S3
Why it's wrong here
SSE-S3 uses AWS-managed keys, not the same CMK.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse SSE-S3 (which uses an AWS-managed key) with SSE-KMS (which allows a customer-managed key), and assume that enabling default encryption with SSE-S3 satisfies the requirement to use the same CMK.
Detailed technical explanation
How to think about this question
SSE-KMS integrates with AWS KMS to provide envelope encryption: each object is encrypted with a unique data key, which is then encrypted with the specified CMK. This allows for centralized key rotation, auditing via CloudTrail, and granular access control through KMS key policies. In a real-world SAP on AWS scenario, using the same CMK for EBS and S3 simplifies compliance audits and reduces the risk of key mismanagement across storage services.
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 |
