The answer is to apply a service control policy (SCP) that denies EC2 actions in any region outside the approved list. This is correct because SCPs operate at the organizational level, setting a permission guardrail that applies to every account under AWS Organizations, effectively preventing developers from launching EC2 instances in unapproved regions regardless of their IAM permissions. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this scenario tests your understanding of centralized governance versus account-level controls; a common trap is choosing IAM permission boundaries, which only restrict a specific role, or a blanket EC2 allow that fails to limit regions. Remember the key distinction: SCPs are for “what you cannot do” across the entire organization, while IAM policies are for “what you can do” within that guardrail. Memory tip: think “SCP = Stop Cross-region Provisioning.”
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.
A company has multiple AWS accounts managed through AWS Organizations. The central IT team wants to allow developers to launch EC2 instances only in specific Regions, but allow full access to all other services. What is the BEST approach?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Configure IAM permissions boundaries on all developer roles to restrict EC2 actions to allowed Regions.
Why wrong: Permissions boundaries are per-role and need to be applied to each role.
B
Apply an SCP that allows EC2 actions only in the allowed Regions.
SCPs deny actions by default, so you must explicitly allow only the desired Regions.
C
Use AWS Config rules to terminate EC2 instances launched in disallowed Regions.
Why wrong: Reactive approach; instances can be launched and incur cost before termination.
D
Create a Service Control Policy (SCP) that denies EC2 actions in disallowed Regions.
Why wrong: Denying disallowed Regions is correct, but the answer as written is ambiguous; the best practice is to explicitly allow only allowed Regions.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Apply an SCP that allows EC2 actions only in the allowed Regions.
Using an SCP with a Deny effect for EC2 actions outside allowed Regions is the best approach because it prevents the action across all accounts. Option A is wrong because IAM permissions boundaries are per-role. Option B is wrong because it allows EC2 in all Regions. Option D is wrong because it allows launching in all Regions.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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 the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related SAP-C02 NAT questions on configuration and troubleshooting.
