The answer is a combination of AWS Service Control Policies (SCPs), AWS CloudFormation StackSets, and AWS Config rules. SCPs centrally enforce that VPC endpoints for S3 can only be created or denied across all accounts in an AWS Organization, providing a guardrail at the organizational level. CloudFormation StackSets then deploy the actual VPC endpoint resources consistently across multiple accounts and Regions, while AWS Config rules continuously detect any non-compliant resources, such as S3 traffic routed through the internet instead of the endpoint. On the ANS-C01 exam, this scenario tests your understanding of how to combine policy, automation, and compliance detection to enforce network security at scale—a common trap is confusing Transit Gateway (a connectivity tool) or VPC Flow Logs (a monitoring tool) with enforcement mechanisms. Remember the triad: SCPs to allow or deny, StackSets to deploy, Config to detect.
ANS-C01 Network Security, Compliance and Governance Practice Question
This ANS-C01 practice question tests your understanding of network security, compliance and governance. 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 using AWS Organizations and wants to centrally manage and enforce the use of VPC endpoints for S3 across all accounts. Which THREE services/tools can be combined to achieve this?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Config rules
Option A (AWS Service Control Policy) can enforce that VPC endpoint creation is allowed or denied. Option C (AWS CloudFormation StackSets) can deploy VPC endpoints across multiple accounts. Option E (AWS Config rules) can detect non-compliant resources. Option B is wrong because VPC Flow Logs do not enforce compliance. Option D is wrong because AWS Transit Gateway is for network connectivity, not policy enforcement.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
VPC Flow Logs
Why it's wrong here
Flow Logs capture traffic, not enforce policies.
✓
AWS Config rules
Why this is correct
Config rules can evaluate whether VPC endpoints exist and trigger remediation.

Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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.

What is the correct answer to this question?
The correct answer is: AWS Config rules — Option A (AWS Service Control Policy) can enforce that VPC endpoint creation is allowed or denied. Option C (AWS CloudFormation StackSets) can deploy VPC endpoints across multiple accounts. Option E (AWS Config rules) can detect non-compliant resources. Option B is wrong because VPC Flow Logs do not enforce compliance. Option D is wrong because AWS Transit Gateway is for network connectivity, not policy enforcement.
