SAP-C02 Service Control Policy (SCP) Practice Question
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. A key principle to apply: service Control Policy (SCP). 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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
All IAM users and roles must use MFA for any AWS API call.
Based on the answer choices, the SCP attached to the root OU must be one that denies any AWS API call unless MFA is present. When such an SCP is applied at the root organizational unit, it affects all IAM users and roles across all accounts in the organization, requiring MFA for every API call. Therefore, option C is correct.

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
All IAM users must use MFA to access the console, but API calls are not affected.
Why it's wrong here
The SCP applies to all actions, including API calls.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse `aws:MultiFactorAuthPresent` with `aws:MultiFactorAuthAge` or assume it only affects console logins, but it actually applies to all API calls and requires MFA for every action, not just initial authentication.
Detailed technical explanation
How to think about this question
The `aws:MultiFactorAuthPresent` key is a boolean that is `true` only when the caller authenticated with a temporary credential that includes MFA (e.g., from STS with `SerialNumber` and `TokenCode`). Long-term access keys (IAM user keys) do not set this key to `true`, so any API call made without MFA will be denied. In a real-world scenario, this SCP ensures that even if an IAM user has console access, they must use MFA to perform any action, including CLI commands.

→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

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.
