The answer is that the SCP policy document lacks a Deny statement for the regions. Even when an SCP like 'DenyOutsideRegions' is attached to the root OU, it only restricts actions if it explicitly uses a Deny effect with a condition key like aws:RequestedRegion. Without that Deny statement, the policy is effectively a list of Allow statements or is incomplete, meaning it does not enforce the intended block on regions such as ap-southeast-1. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this tests your understanding that SCPs must use explicit Deny to override Allow permissions; a common trap is assuming that simply naming an SCP or attaching it to an OU is enough to enforce restrictions. Remember that SCPs are like a guardrail—they only stop traffic if they say "No" (Deny), not if they are silent. Memory tip: "No Deny, no deny"—if the policy document lacks a Deny statement, the SCP is not restricting regions.
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.
Network Topology
Refer to the exhibit. A company has an SCP named 'DenyOutsideRegions' attached to the root OU. The SCP is intended to deny all actions outside us-east-1 and eu-west-1. However, users in a member account are still able to launch EC2 instances in ap-southeast-1. 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 policy document does not contain a Deny statement for the regions.
Option B is correct because the SCP shown is only a list of policies; the actual policy content (the statement) is not displayed. It is possible that the SCP does not contain the intended deny rule or has an Allow effect that overrides. Option A is wrong because SCPs affect all users, including root. Option C is wrong because SCPs can deny actions based on region conditions. Option D is wrong because SCPs apply to all services uniformly unless specified otherwise.
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 SCP is not applied to the root user of the member account.
Why it's wrong here
SCPs apply to root user as well.
✗
The SCP cannot restrict actions based on region.
Why it's wrong here
SCPs can use condition keys like aws:RequestedRegion.
✓
The SCP policy document does not contain a Deny statement for the regions.
Why this is correct
The exhibit only shows the policy metadata, not the content.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Standard ACLs match source addresses.
✗
The SCP is overridden by an Allow policy attached to the account.
Why it's wrong here
Deny always overrides Allow in SCPs.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. 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. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
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 SAP-C02 ACL questions on filtering logic and placement.
