- A
Use AWS Organizations to create a new IAM user in each member account with full permissions, and disable the root user.
Why wrong: AWS Organizations cannot create IAM users in member accounts, and the root user cannot be disabled.
- B
Capture the root user email addresses and passwords in a secure password manager and share them with the security team.
Why wrong: Sharing root credentials is insecure and should be avoided.
- C
Use the management account to assume an IAM role in each member account that has permissions to reset the root user password and enable MFA. Then, rotate the root user password and enable MFA.
This allows central management without sharing credentials.
- D
Use AWS Single Sign-On (SSO) to grant the security team access to the root user credentials for each account.
Why wrong: AWS SSO does not manage root user credentials.
Quick Answer
The answer is to use the management account to assume an IAM role in each member account that has permissions to reset the root user password and enable MFA, then rotate the password and enable MFA. This is correct because AWS Organizations allows you to create a predefined IAM role—typically named OrganizationAccountAccessRole—in every member account, which can be assumed from the management account with full administrative privileges, including the ability to manage root user credentials. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this scenario tests your understanding that root user access is not directly managed through Organizations or IAM Identity Center; instead, you must delegate via cross-account IAM roles. A common trap is assuming you can use AWS SSO or Organizations APIs to control root credentials, but neither service has that capability. Memory tip: think “Role, not Root”—always use an IAM role from the management account to securely manage the root user of member accounts.
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 startup is launching a new multi-account AWS environment using AWS Organizations. They want to ensure that only the central security team has access to the root user of each member account. Additionally, they want to enable multi-factor authentication (MFA) for the root user of each account. The security team has access to the management account. What is the MOST secure and efficient way to meet these requirements?
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
Use the management account to assume an IAM role in each member account that has permissions to reset the root user password and enable MFA. Then, rotate the root user password and enable MFA.
Option B is correct because AWS Organizations allows you to create an IAM role in each member account that can be assumed from the management account. The root user password can be reset and MFA can be enabled by assuming the role with appropriate permissions. Option A is incorrect because you cannot use AWS Organizations to manage root user credentials directly. Option C is incorrect because AWS Single Sign-On (now IAM Identity Center) does not manage root users. Option D is inefficient and insecure as it requires sharing root credentials.
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
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.
