Full question →hardmultiple choiceObjective-mapped
A healthcare document service must ensure that only encrypted EBS volumes can be created in the account. What is the strongest preventive control?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Use an SCP that denies ec2:CreateVolume when the encrypted condition is false
An SCP can prevent noncompliant volume creation across accounts in an organization.
B
Distractor review
Tag encrypted volumes after creation
Tags identify resources but do not enforce encryption.
C
Distractor review
Enable VPC Flow Logs
Flow Logs monitor network traffic and do not control EBS encryption.
D
Distractor review
Run a daily Lambda function to encrypt unencrypted volumes
Reactive remediation leaves a window of exposure.
Common exam trap
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Technical deep dive
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
- Standard ACLs match source addresses.
- Extended ACLs can match source, destination, protocol and ports.
- The first matching ACL entry is used.
- There is usually an implicit deny at the end.
TExam Day Tips
- Check inbound versus outbound direction.
- Read the ACL from top to bottom.
- Look for a broader permit or deny above the intended line.

FAQ
Questions learners often ask
What does this SAA-C03 question test?
Standard ACLs match source addresses.
What is the correct answer to this question?
The correct answer is: Use an SCP that denies ec2:CreateVolume when the encrypted condition is false — A deny SCP is a preventive governance control that stops non-encrypted EBS volume creation before it happens.
