SAP-C02 Practice Question: Design Solutions for Organizational Complexity
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.)
⚠ Common exam trap
Test-takers frequently 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.
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.
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.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Disable public access to all S3 buckets and restrict cross-account access.
Why it's wrong here
This is a part of data perimeter but not sufficient; exfiltration can still occur via authorized services like EC2 to external IPs.
- ✓
Use AWS Resource Access Manager to share resources only with trusted accounts.
Why this is correct
RAM allows fine-grained control over resource sharing within the organization.
- ✓
Use SCPs to deny access to external AWS accounts unless explicitly allowed.
Why this is correct
SCPs can prevent resources from being shared or accessed from outside the organization.
- ✗
Use VPC endpoints for all AWS services and ensure they are private.
Why it's wrong here
VPC endpoints ensure traffic stays within the AWS network but do not prevent exfiltration to unauthorized accounts.
- ✗
Use security groups to restrict outbound traffic to known IP addresses.
Why it's wrong here
Security groups are stateful but cannot control data exfiltration via services like S3 that use public endpoints.
