The answer is a missing explicit allow for the sts:GetSessionToken action in the SCP. When an SCP denies all actions unless MFA is present, it blocks the initial STS call that generates the temporary, MFA-authenticated credentials needed to access the console. Without an explicit allow for sts:GetSessionToken, the SCP denies that action even before MFA can be verified, creating a catch-22 where users cannot authenticate to prove they have MFA. This scenario tests your understanding of how SCPs interact with the STS token service, a common trap on the SAP-C02 exam where candidates assume MFA enforcement alone is sufficient. The key insight is that SCPs evaluate before IAM policies, so they must explicitly permit the credential-granting action. Memory tip: think of it as “you can’t show your badge if the door won’t let you reach the scanner”—the SCP must allow the token request first.
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 with 100 accounts. The security team wants to enforce that all IAM users must use multi-factor authentication (MFA) to access the AWS Management Console. They create an SCP that denies all actions if MFA is not present. However, some users report that they cannot access the console even with MFA. What is the most likely reason?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The SCP does not include an explicit allow for the sts:GetSessionToken action.
Option D is correct because the SCP must allow the STS:GetSessionToken action to allow MFA based temporary credentials. Option A is wrong because MFA is not required for root user in this context. Option B is wrong because SCPs override IAM permissions. Option C is wrong because SCPs apply to all principals, including users with administrative privileges.
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.
✓
The SCP does not include an explicit allow for the sts:GetSessionToken action.
Why this is correct
Without allowing STS:GetSessionToken, the MFA challenge cannot be completed.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Authentication checks who the user is.
✗
The IAM policy attached to the users does not allow any actions.
Why it's wrong here
Even if IAM policy allows, SCP can deny.
✗
The SCP does not apply to users who have administrative privileges.
Why it's wrong here
SCPs apply to all IAM principals in the account.
✗
The SCP also denies access to the root user of each account.
Why it's wrong here
Root user is not affected by SCPs.
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.
