SCS-C02 Identity and Access Management Practice Question
This SCS-C02 practice question tests your understanding of identity and access management. 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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The user cannot assume the role because the Deny statement blocks all actions when MFA is not present
Option D is correct because the Deny statement applies to all actions if MFA is not present, so the AssumeRole action is denied. Option A is incorrect because the Allow statement is overridden by the Deny. Option B is incorrect because the Deny is explicit. Option C is incorrect because the Deny applies to all actions including AssumeRole.
Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
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 user can assume the role because the Allow statement grants it
Why it's wrong here
The Deny statement overrides the Allow.
✓
The user cannot assume the role because the Deny statement blocks all actions when MFA is not present
Why this is correct
The Deny condition blocks all actions if MFA is false.
Related concept
Standard ACLs match source addresses.
✗
The user can assume the role because the Deny statement does not apply to sts:AssumeRole
Why it's wrong here
The Deny uses Action '*' which includes sts:AssumeRole.
✗
The user cannot assume the role because the Allow statement requires MFA
Why it's wrong here
The Allow does not require MFA, but the Deny does.
Common exam traps
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Detailed technical explanation
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
Standard ACLs match source addresses.
Extended ACLs can match source, destination, protocol and ports.
The first matching ACL entry is used.
There is usually an implicit deny at the end.
TExam Day Tips
→Check inbound versus outbound direction.
→Read the ACL from top to bottom.
→Look for a broader permit or deny above the intended line.
Key takeaway
ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
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 ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related SCS-C02 ACL questions on filtering logic and placement.

What is the correct answer to this question?
The correct answer is: The user cannot assume the role because the Deny statement blocks all actions when MFA is not present — Option D is correct because the Deny statement applies to all actions if MFA is not present, so the AssumeRole action is denied. Option A is incorrect because the Allow statement is overridden by the Deny. Option B is incorrect because the Deny is explicit. Option C is incorrect because the Deny applies to all actions including AssumeRole.
