SCS-C02 Data Protection Practice Question
Which TWO actions can help protect data at rest in Amazon EBS volumes? (Choose 2.)
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 EBS encryption by default in the AWS Account settings.
Options D and E are correct. D: Enabling EBS encryption by default in AWS Account settings ensures that all new EBS volumes are encrypted at rest. E: Using encrypted EBS volumes with AWS KMS customer-managed keys provides granular control over encryption keys. Option A is incorrect because EBS snapshots are not automatically encrypted by default; they can be encrypted during copy or by enabling encryption by default for volumes. Option B is incorrect because encryption at rest is independent of instance type; any instance type can use encrypted EBS volumes. Option C is incorrect because configuring the OS to use encrypted file systems is not the primary method for protecting data at rest on EBS; EBS encryption at the volume level is more appropriate.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable automatic encryption of EBS snapshots by default.
Why it's wrong here
Snapshots are not automatically encrypted; encryption is done during copy.
- ✗
Use an instance type that supports encryption at rest.
Why it's wrong here
Instance type does not determine EBS encryption.
- ✗
Configure the operating system to use encrypted file systems.
Why it's wrong here
This is a client-side measure, not an AWS-native one for data at rest.
- ✓
Enable EBS encryption by default in the AWS Account settings.
Why this is correct
This encrypts all new EBS volumes.
- ✓
Use encrypted EBS volumes with AWS KMS customer-managed keys.
Why this is correct
This encrypts the volume at rest.
