- A
AWS Directory Service for Microsoft Active Directory.
Why wrong: Directory Service is for AD-based identity, not SAML federation.
- B
Amazon Cognito user pools.
Why wrong: Cognito is for external user identity, not enterprise SSO for AWS accounts.
- C
AWS IAM Identity Center.
IAM Identity Center integrates with SAML 2.0 IdPs and provides SSO across multiple AWS accounts.
- D
AWS Identity and Access Management (IAM) with SAML federation.
Why wrong: IAM supports SAML federation but is more complex to manage for multiple accounts; Identity Center is the recommended service.
SAP-C02 Practice Question: Design Solutions for Organizational Complexity
This SAP-C02 practice question tests your understanding of design solutions for organizational complexity. 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.
A company wants to implement a single sign-on (SSO) solution for its employees to access multiple AWS accounts. The company has an existing identity provider (IdP) that supports SAML 2.0. Which AWS service should be used to integrate with the IdP?
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
AWS IAM Identity Center.
AWS IAM Identity Center (formerly AWS SSO) is the recommended service for centrally managing SSO access to multiple AWS accounts. It natively integrates with external SAML 2.0 identity providers, allowing you to define permissions sets that govern user access across accounts without creating IAM users. This provides a single place to manage user assignments and enforce least-privilege access across your AWS Organization.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
AWS Identity and Access Management (IAM) with SAML federation.
Why it's wrong here
IAM supports SAML federation but is more complex to manage for multiple accounts; Identity Center is the recommended service.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse IAM SAML federation (which works for a single account) with IAM Identity Center (which is the correct multi-account SSO solution), leading them to select Option D because they know SAML 2.0 is supported, but they miss the requirement for multiple AWS accounts.
Detailed technical explanation
How to think about this question
IAM Identity Center uses a service-linked role and a built-in identity store (or external IdP) to issue temporary credentials via AWS STS. When a user authenticates via SAML, IAM Identity Center maps them to a permission set that defines IAM policies, and then generates a role session in the target account. This avoids the need to create IAM roles per account per user, and supports attribute-based access control (ABAC) using SAML attributes.
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.
