The answer is to use AWS Config rules to detect roles without the 'Approved' tag and mark them as non-compliant, combined with a Service Control Policy (SCP) that denies role creation unless the request originates from an approved pipeline, and an AWS Lambda function triggered by CloudTrail to remediate non-compliant roles. This works because least privilege IAM role creation with approval workflow requires both detective and preventive controls: AWS Config provides continuous compliance monitoring by flagging untagged roles, while the SCP blocks unauthorized creation at the organization level, and Lambda automates remediation. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this scenario tests your ability to distinguish between logging (CloudTrail) and enforcement (SCP/Config), with a common trap being to select CloudTrail alone as a preventive measure—it is only detective. Remember the memory tip: "Tag, Block, Fix"—Config tags for detection, SCP blocks creation, Lambda fixes violations.
SAP-C02 Practice Question: Design Solutions for Organizational Complexity
This SAP-C02 practice question tests your understanding of design solutions for organizational complexity. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
A company uses AWS Organizations and wants to implement a least-privilege model for IAM roles. The security team needs to ensure that no IAM role can be created without an approval workflow. Which THREE steps should the company take?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "least"
Why it matters: You want the option with minimum overhead, fewest steps, or lowest impact — not the most feature-rich or comprehensive answer.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create an AWS Lambda function that is triggered by CloudTrail events to automatically tag approved roles.
Options A, C, and D are correct. Option B is wrong because CloudTrail is logging, not preventive. Option E is wrong because SCPs cannot enforce approval workflows.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Create an AWS Lambda function that is triggered by CloudTrail events to automatically tag approved roles.
Why this is correct
Automates tagging after approval.
Clue confirmation
The clue word "least" in the question point toward this answer.
Related concept
Authentication checks who the user is.
✓
Use a service control policy (SCP) to deny iam:CreateRole unless a specific tag (e.g., 'Approved') is present.
Why this is correct
SCPs can enforce tag-based conditions.

The clue word "least" in the question point toward this answer.
Related concept
Authentication checks who the user is.
✗
Use AWS CloudFormation StackSets to deploy IAM roles across accounts.
Why it's wrong here
Does not enforce approval.
✗
Enable AWS CloudTrail to log all IAM role creation events.
Why it's wrong here
Logging does not enforce approval.
✓
Use AWS Config rules to detect roles without the 'Approved' tag and mark them as non-compliant.
Why this is correct
Reactive enforcement and visibility.
Clue confirmation
The clue word "least" in the question point toward this answer.
Related concept
Authentication checks who the user is.
Common exam traps
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.
Detailed technical explanation
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.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
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 to study next
Got this wrong? Here's your next step.
Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related SAP-C02 questions on access control and AAA configuration.
