SAA-C03 Design Secure Architectures Practice Question
This SAA-C03 practice question tests your understanding of design secure architectures. 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.
Exhibit
CloudTrail event for a newly created role:
{
"eventSource": "iam.amazonaws.com",
"eventName": "CreateRole",
"requestParameters": {
"roleName": "AppDeployRole",
"permissionsBoundary": null,
"assumeRolePolicyDocument": "..."
},
"userIdentity": {
"arn": "arn:aws:sts::111122223333:assumed-role/AutomationRole/ci-run-9841"
}
}
Current guardrails:
- Developers can call iam:CreateRole
- The automation tool sometimes omits the permissions boundary field
- The organization uses AWS Organizations with multiple member accounts
Based on the exhibit, an automation pipeline in several member accounts creates IAM roles for application deployments. Security says no future role may exceed the approved boundary arn:aws:iam::123456789012:policy/DeployBoundary, even if someone later attaches AdministratorAccess. What should you implement to enforce this across the organization?

A
Attach DeployBoundary to the automation role only, because that automatically forces every created role to inherit the same boundary.
Why wrong: A boundary on the creator role does not automatically propagate to newly created roles. The new role must either be created with the boundary or be blocked unless it includes the approved boundary. Creator boundaries and target-role boundaries are separate controls.
B
Create an SCP that denies iam:CreateRole and iam:PutRolePermissionsBoundary unless aws:RequestTag equals DeployBoundary.
Why wrong: Request tags are useful for tagging governance, but they do not validate which permissions boundary is attached to the new role. The enforcement must check the permissions boundary parameter or the boundary ARN condition, not a general request tag.
C
Create an SCP that denies iam:CreateRole unless iam:PermissionsBoundary equals arn:aws:iam::123456789012:policy/DeployBoundary, and also deny removing that boundary from created roles.
This is the strongest organization-wide enforcement. The SCP prevents role creation unless the approved permissions boundary is attached, and it can also prevent boundary removal later. That ensures the maximum effective permissions for all created roles remain capped, even if someone attaches a broader identity policy afterward.
D
Use AWS Access Analyzer to automatically attach the approved boundary whenever a role is created without one.
Why wrong: Access Analyzer is a detection and analysis service, not an enforcement mechanism that modifies IAM resources. It can help identify overly broad access, but it cannot automatically attach permissions boundaries to IAM roles during creation.

Correct answer & explanation
✓
Create an SCP that denies iam:CreateRole unless iam:PermissionsBoundary equals arn:aws:iam::123456789012:policy/DeployBoundary, and also deny removing that boundary from created roles.
Option C is correct because it uses an SCP to enforce that any IAM role creation must include the specific permissions boundary `arn:aws:iam::123456789012:policy/DeployBoundary`, and also prevents removal or modification of that boundary from existing roles. This ensures that even if an attacker or administrator later attaches a policy like AdministratorAccess, the effective permissions are still limited by the boundary, meeting the security requirement across all member accounts in the organization.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✗
Attach DeployBoundary to the automation role only, because that automatically forces every created role to inherit the same boundary.
Why it's wrong here
A boundary on the creator role does not automatically propagate to newly created roles. The new role must either be created with the boundary or be blocked unless it includes the approved boundary. Creator boundaries and target-role boundaries are separate controls.
✗
Create an SCP that denies iam:CreateRole and iam:PutRolePermissionsBoundary unless aws:RequestTag equals DeployBoundary.
Why it's wrong here
Request tags are useful for tagging governance, but they do not validate which permissions boundary is attached to the new role. The enforcement must check the permissions boundary parameter or the boundary ARN condition, not a general request tag.
✓
Create an SCP that denies iam:CreateRole unless iam:PermissionsBoundary equals arn:aws:iam::123456789012:policy/DeployBoundary, and also deny removing that boundary from created roles.
Why this is correct
This is the strongest organization-wide enforcement. The SCP prevents role creation unless the approved permissions boundary is attached, and it can also prevent boundary removal later. That ensures the maximum effective permissions for all created roles remain capped, even if someone attaches a broader identity policy afterward.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing the condition key `aws:RequestTag` (used for tagging) with `iam:PermissionsBoundary` (the actual boundary ARN), leading candidates to pick Option B, which would not enforce the boundary requirement.
Detailed technical explanation
How to think about this question
AWS Organizations Service Control Policies (SCPs) operate at the account level, not the resource level, and can deny IAM actions based on condition keys like `iam:PermissionsBoundary`. The condition `iam:PermissionsBoundary` checks the ARN of the boundary being passed during role creation, while `iam:PassRole` is not relevant here. In a real-world scenario, if a developer creates a role without a boundary, the SCP in C would deny the action, forcing compliance; without the second deny, a user could later remove the boundary via `iam:PutRolePermissionsBoundary` with a different ARN, bypassing the restriction.

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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.

What is the correct answer to this question?
The correct answer is: Create an SCP that denies iam:CreateRole unless iam:PermissionsBoundary equals arn:aws:iam::123456789012:policy/DeployBoundary, and also deny removing that boundary from created roles. — Option C is correct because it uses an SCP to enforce that any IAM role creation must include the specific permissions boundary `arn:aws:iam::123456789012:policy/DeployBoundary`, and also prevents removal or modification of that boundary from existing roles. This ensures that even if an attacker or administrator later attaches a policy like AdministratorAccess, the effective permissions are still limited by the boundary, meeting the security requirement across all member accounts in the organization.
