Quick Answer
The answer is AWS Key Management Service (KMS) and Amazon EBS encryption. These two services work together to provide data encryption at rest for SAP migration, because EBS encryption uses KMS to create and manage the customer master keys that automatically encrypt EBS volumes and their snapshots, ensuring that all data stored on the underlying storage is protected without requiring any changes to the SAP application itself. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding of the shared responsibility model and the specific encryption services that directly apply to storage layers, not network or certificate-based tools. A common trap is confusing AWS CloudHSM or AWS Certificate Manager with at-rest encryption, but remember that CloudHSM is a dedicated hardware security module for key storage, not a direct encryption service for EBS, and Certificate Manager handles TLS certificates only. Memory tip: think “EBS + KMS = encrypted disks at rest,” and avoid any service that doesn’t touch the storage layer.
This PAS-C01 practice question tests your understanding of migration. 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 migrating SAP applications to AWS and needs to ensure that the migration complies with regulatory requirements for data encryption. Which TWO AWS services can be used to encrypt data at rest? (Choose TWO.)
AWS WAF
Why wrong: WAF is a web application firewall.
AWS Certificate Manager (ACM)
Why wrong: ACM is for SSL/TLS certificates, not data at rest encryption.
Amazon EBS encryption
EBS encryption encrypts volumes at rest.
AWS CloudHSM
Why wrong: CloudHSM provides hardware security modules but not typically used for EBS encryption.
AWS Key Management Service (KMS)
KMS manages encryption keys for EBS and other services.
Answer choices
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 encrypts volumes at rest, and AWS KMS manages encryption keys. Option C is wrong because AWS Certificate Manager is for SSL/TLS certificates. Option D is wrong because AWS CloudHSM is for hardware security modules, but not directly for data at rest encryption of EBS. Option E is wrong because AWS WAF is for web application firewall.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
AWS WAF

Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
