- A
Disable public access to all S3 buckets and restrict cross-account access.
Why wrong: This is a part of data perimeter but not sufficient; exfiltration can still occur via authorized services like EC2 to external IPs.
- B
Use AWS Resource Access Manager to share resources only with trusted accounts.
RAM allows fine-grained control over resource sharing within the organization.
- C
Use SCPs to deny access to external AWS accounts unless explicitly allowed.
SCPs can prevent resources from being shared or accessed from outside the organization.
- D
Use VPC endpoints for all AWS services and ensure they are private.
Why wrong: VPC endpoints ensure traffic stays within the AWS network but do not prevent exfiltration to unauthorized accounts.
- E
Use security groups to restrict outbound traffic to known IP addresses.
Why wrong: Security groups are stateful but cannot control data exfiltration via services like S3 that use public endpoints.
Quick Answer
The correct answer is to use Service Control Policies (SCPs) to deny access to external AWS accounts unless explicitly allowed, combined with AWS Resource Access Manager (RAM) to share resources only with specific accounts. SCPs enforce a data perimeter by acting as a guardrail at the organization level, blocking any cross-account access to external principals unless a specific allow policy exists, which directly prevents data exfiltration to unauthorized accounts. RAM complements this by enabling controlled, explicit sharing of resources like subnets or transit gateways only with trusted accounts or OUs, ensuring no accidental exposure. On the SAP-C02 exam, this pairing tests your understanding of governance versus resource sharing—a common trap is choosing VPC peering or IAM roles alone, which lack the organization-wide boundary enforcement. Remember the mnemonic: SCPs say "no by default," RAM says "yes only to known friends."
SAP-C02 Practice Question: Design Solutions for Organizational Complexity
This SAP-C02 practice question tests your understanding of design solutions for organizational complexity. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 wants to implement a data perimeter across all AWS accounts to prevent data exfiltration. Which TWO strategies should the company use? (Choose TWO.)
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
Use AWS Resource Access Manager to share resources only with trusted accounts.
Option B is correct because AWS Resource Access Manager (RAM) enables you to share resources such as subnets, transit gateways, and License Manager configurations only with specific AWS accounts or organizational units, which directly supports a data perimeter by preventing unintended cross-account access. Option C is correct because Service Control Policies (SCPs) can be applied at the organization root, OU, or account level to deny access to external AWS accounts unless explicitly allowed, effectively creating a boundary that prevents data exfiltration to unauthorized accounts.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse network-level controls (like VPC endpoints or security groups) with identity and resource-based perimeter controls, leading them to choose options D or E, which only address network paths and not the authorization boundaries needed to prevent data exfiltration across accounts.
Detailed technical explanation
How to think about this question
SCPs work by applying allow lists or deny lists at the AWS Organizations level, using the same AWS IAM policy language but without granting permissions; they only set boundaries. When combined with RAM, which uses resource-based policies to share resources without creating IAM roles, the data perimeter becomes enforceable at both the resource access and organizational boundary levels. A real-world scenario is a multi-account environment where SCPs deny all actions to external accounts unless the resource is explicitly shared via RAM, preventing accidental data leakage through cross-account IAM roles.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
