- A
EBS volumes and EFS file system
Both require separate encryption enablement.
- B
Application Load Balancer and EFS
Why wrong: ALB does not store data at rest.
- C
EFS file system and S3 bucket
Why wrong: S3 is not mentioned in the stack.
- D
CloudWatch Logs and EBS volumes
Why wrong: CloudWatch Logs can be encrypted with KMS but is not part of the stack.

PAS-C01 Design of SAP Workloads on AWS Practice Question
This PAS-C01 practice question tests your understanding of design of sap workloads on aws. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 SAP environment on AWS uses a shared /sapmnt file system via Amazon EFS. The company wants to encrypt data at rest for the entire stack. Which services require separate encryption configurations?
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
✓
EBS volumes and EFS file system
Amazon EBS volumes and Amazon EFS file systems each require separate encryption configurations because they use distinct encryption mechanisms. EBS uses AWS KMS keys per volume at the block level, while EFS uses a different KMS key configuration at the file system level. Both must be explicitly enabled to achieve full at-rest encryption for the SAP stack.
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.
- ✓
EBS volumes and EFS file system
Why this is correct
Both require separate encryption enablement.

- ✗
Application Load Balancer and EFS
Why it's wrong here
ALB does not store data at rest.
- ✗
EFS file system and S3 bucket
Why it's wrong here
S3 is not mentioned in the stack.
- ✗
CloudWatch Logs and EBS volumes
Why it's wrong here
CloudWatch Logs can be encrypted with KMS but is not part of the stack.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume a single encryption setting (like enabling EBS default encryption) covers all storage services, but AWS requires separate encryption configurations for each service (EBS, EFS, S3, etc.) because they use independent encryption mechanisms and KMS key policies.
Detailed technical explanation
How to think about this question
EBS encryption uses AES-256 with a unique DEK per volume, managed via KMS, and can be enabled at volume creation or via default account settings. EFS encryption at rest uses KMS keys at the file system level, with data encrypted using AES-256-GCM before being written to disk. A common real-world scenario is when an SAP administrator enables EBS encryption but forgets to enable EFS encryption, leaving the shared /sapmnt data unencrypted despite the rest of the stack being protected.
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.
