PAS-C01 Amazon EBS Encryption Practice Question
A company is migrating an SAP HANA workload to Amazon EC2. Which configuration ensures data encryption at rest and in transit without performance degradation?
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
✓
Enable Amazon EBS encryption with SSE-EBS for at-rest and enable in-transit encryption using TLS.
Amazon EBS encryption (SSE-EBS) provides at-rest encryption with minimal performance overhead (handled at the hypervisor layer with hardware acceleration), and TLS secures data in transit. Option A is incorrect because client-side encryption adds CPU overhead on the EC2 instance, potentially degrading SAP HANA performance. Option B is incorrect because VPC peering does not encrypt traffic in transit; TLS must be used. Option C is incorrect as it compromises security.
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 with AWS KMS for SAP HANA data files.
Why it's wrong here
Client-side encryption on SAP application servers adds computational overhead, potentially degrading performance.
- ✗
Use EBS encryption with AWS KMS for at-rest and VPC peering for in-transit.
Why it's wrong here
VPC peering does not encrypt traffic; it only provides network connectivity. SSE-KMS encrypts EBS volumes at rest but does not address in-transit encryption.
- ✗
Disable encryption to maximize performance; use security groups for isolation.
Why it's wrong here
Disabling encryption removes all protection, violating security requirements.
- ✓
Enable Amazon EBS encryption with SSE-EBS for at-rest and enable in-transit encryption using TLS.
Why this is correct
SAP HANA TDE with AWS KMS provides efficient at-rest encryption, and TLS provides efficient in-transit encryption, meeting the performance requirement.
