- A
Attach a Service Control Policy (SCP) to the production OU that denies sts:AssumeRole unless the request source IP is within the corporate range.
SCPs can enforce conditions on API calls.
- B
Use a VPC endpoint for STS and restrict access to the endpoint.
Why wrong: VPC endpoints do not restrict source IP; they restrict network path.
- C
Configure AWS WAF to block requests from IPs outside the corporate range.
Why wrong: WAF is for web application traffic, not IAM API calls.
- D
Add a condition to the trust policy of each IAM role that requires the source IP to be in the corporate range.
Trust policy conditions can restrict who can assume the role.
- E
Attach a Service Control Policy (SCP) to each IAM role that denies assume role unless the source IP is corporate.
Why wrong: SCPs cannot be attached to IAM roles.
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 has a multi-account AWS environment. The security team wants to enforce that all IAM roles in the production accounts can only be assumed from a specific IP range (the corporate network). Which TWO approaches can achieve this?
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
Attach a Service Control Policy (SCP) to the production OU that denies sts:AssumeRole unless the request source IP is within the corporate range.
Option A is correct because an SCP attached to the production OU can deny sts:AssumeRole actions unless the request's source IP falls within the corporate range. SCPs operate at the organization level and apply to all accounts in the OU, providing a centralized guardrail that cannot be overridden by account administrators. This enforces the IP restriction across all IAM roles in the production accounts without modifying individual role trust policies.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse SCPs with resource-based policies, thinking SCPs can be attached to individual IAM roles, or they mistakenly believe WAF or VPC endpoints can control IAM API calls, when in fact only SCPs and trust policies directly enforce source IP restrictions on sts:AssumeRole.
Detailed technical explanation
How to think about this question
The condition key aws:SourceIp in an SCP or trust policy evaluates the IP address of the principal making the sts:AssumeRole call. However, SCPs using aws:SourceIp do not work when the request comes through an AWS service (e.g., from an EC2 instance with a public IP) because the source IP is then the service's internal IP; in such cases, you must use aws:VpcSourceIp instead. Trust policies on IAM roles are evaluated per role and can include conditions like 'StringEquals' on aws:SourceIp, but they require explicit configuration on every role, making SCPs more scalable for multi-account environments.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
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.
