Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A deployment engineer created an IAM role for an automation workflow (AppDeployRole). The role has an attached identity policy that allows iam:CreateRole for specific resource ARNs. However, the role is also created with a permission boundary named DeployBoundary. The DeployBoundary policy currently does not include the iam:CreateRole action. During execution, the automation fails with AccessDenied for iam:CreateRole, even though the attached identity policy allows it. What is the best fix?
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
Distractor review
Edit AppDeployRole’s attached identity policy to add iam:CreateRole again; permission boundaries only apply when permissions are missing.
Permission boundaries are an additional authorization constraint (an upper limit). Even if the role’s identity policy allows an action, IAM will deny it when the permission boundary does not allow the action for the resource.
B
Best answer
Update DeployBoundary to allow iam:CreateRole for only the required resource ARNs, following least privilege.
IAM permission boundaries define the maximum set of permissions the role can use. To permit iam:CreateRole, the DeployBoundary must explicitly allow iam:CreateRole (and scope it to the required resources). The attached identity policy alone is not sufficient when the boundary is more restrictive.
C
Distractor review
Remove the permission boundary from the role because permission boundaries are not enforced at runtime.
Permission boundaries are enforced during authorization checks. Removing the boundary would eliminate the security control described in the scenario and is not the least-privilege fix.
D
Distractor review
Encrypt the deployment artifacts with KMS so IAM denies become KMS authorization failures.
Encryption with KMS is unrelated to IAM authorization for iam:CreateRole. The failure is an IAM action authorization problem, not a data-encryption permission issue.
Common exam trap
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Technical deep dive
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
- Authentication checks who the user is.
- Authorization controls what the user is allowed to do after login.
- Privilege levels affect access to EXEC and configuration commands.
- AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
- Do not assume successful login means full administrative access.
- Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
- Separate login problems from permission problems before choosing the answer.

FAQ
Questions learners often ask
What does this SAA-C03 question test?
Authentication checks who the user is.
What is the correct answer to this question?
The correct answer is: Update DeployBoundary to allow iam:CreateRole for only the required resource ARNs, following least privilege. — With IAM permission boundaries, IAM authorization is effectively limited to the intersection of (1) the role’s identity-based allow policy and (2) the permission boundary policy. In this case, AppDeployRole’s identity policy allows iam:CreateRole, but DeployBoundary does not; therefore IAM denies the action. The correct fix is to update DeployBoundary to allow iam:CreateRole for only the specific resource ARNs needed by the automation workflow. A is incorrect because adding or re-adding permissions to the role’s identity policy does not override a restrictive permission boundary. C is incorrect because permission boundaries are enforced and removing them undermines the intended control. D is incorrect because KMS encryption does not change authorization for IAM control-plane actions like iam:CreateRole.
