- A
Implement an S3 bucket policy that restricts access based on the aws:SourceVpce condition key.
Restricts access to requests from specific VPC endpoints.
- B
Create an IAM policy in each account that denies access unless the request comes from the approved IP range.
Why wrong: Not centralized; requires per-account management.
- C
Use AWS PrivateLink to access all AWS services from within the VPC.
Why wrong: PrivateLink restricts network path but not IP-based location.
- D
Create a service control policy (SCP) that denies access to resources unless the request originates from the approved IP address range.
SCP applies to all accounts in the organization.
- E
Use AWS Resource Access Manager to share resources with approved accounts only.
Why wrong: This controls access at the account level, not network.
Quick Answer
The correct answer is to create a service control policy (SCP) that denies access unless the request originates from an approved IP address range, combined with an S3 bucket policy that uses the aws:SourceVpce condition to restrict access to specific VPC endpoints. An SCP with aws:SourceIp provides a centralized, account-wide network boundary across the entire AWS Organization, ensuring that no user or role can bypass the approved IP range, while the S3 bucket policy with aws:SourceVpce locks down data access to traffic flowing through a specific VPC endpoint, creating a layered defense. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this scenario tests your understanding of how to enforce a data perimeter using both organizational-level policies and resource-based policies; a common trap is choosing an IAM policy or a service control that restricts actions instead of network origin. Remember the memory tip: “SCP for the source IP, bucket policy for the VPCe” to keep the two distinct layers straight.
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 is setting up a new AWS Organization and wants to implement a data perimeter to ensure that data can only be accessed from approved network locations. Which TWO actions should the company take?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Implement an S3 bucket policy that restricts access based on the aws:SourceVpce condition key.
Options B and D are correct. B: An SCP with a condition on aws:SourceIp restricts access based on IP address across all accounts. D: An S3 bucket policy with a condition on aws:SourceVpce restricts access to specific VPC endpoints. Option A is wrong because it's not centralized. Option C is wrong because it restricts service but not network location. Option E is wrong because it restricts actions but not network.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
